The project combines the expertise of College of Science Professor Ramin M. Hakami’s group in extracellular vesicle (EV) biology, and that of College of Engineering and Computing Associate Professor Remi Veneziano’s group in bioengineering and materials characterization, at 91�� with Phase’s vision to create an end-to-end, automated microfluidic platform that brings together custom device design, scalable 3D-printed polydimethylsiloxane (PDMS) chip manufacturing, and automated fluid handling. Specifically, this project leverages the microfluidic EV platform jointly developed and published by the Veneziano and Hakami groups.

Microfluidic devices use tiny channels to control small amounts of fluid and recreate environments on a cellular scale. They model human biology more realistically than flat cell cultures, making them important for drug discovery, disease research, and toxicology. Microfluidics are especially timely as the FDA has announced plans to phase out some animal testing requirements and encourage more human-relevant methods.

Today, producing complex PDMS microfluidic devices often requires cleanrooms, manual optimization, and repeated trial-and-error. The NSF-supported work is designed to reduce that bottleneck by using thermal and curing models to predict how PDMS will behave during printing, then optimize print parameters before a device is manufactured.

“This partnership helps us move one step closer to a fully automated, scalable microfluidic platform,” said Jeff Schultz, principal investigator and co-founder of Phase, which is headquartered in Charlotte, North Carolina. “Our goal is to make microfluidic technology more reproducible and more accessible to researchers and companies working to develop better human-relevant models.”

George Mason researchers will help characterize the printed devices for dimensional accuracy, surface quality, batch-to-batch consistency, and biological function. The team will also test a device designed to study EV function. EVs are nanoparticles that are released by cells and play critical roles in intercellular communication. They have been shown to carry important regulatory functions in various human diseases, such as cancer, infectious disease, and neurological disorders, and are also highly advantageous for use in drug delivery.

“Being able to rapidly and cost‑effectively prototype and fabricate custom microfluidic devices will significantly enhance our capacity to design relevant microphysiological systems and will help broaden access to this technology to many research laboratories” said Veneziano.

“Our microfluidic device empowers researchers to conduct functional EV studies with ease and under physiologically relevant conditions. Through our partnership with Phase to 3D print the chips, we will be able to deliver more reliable, cost-effective, and commercially viable tools to the EV scientific community,” said Hakami, co-director of the Center for Infectious Disease Research at George Mason.

For Phase, the NSF grant builds on a growing base of support from federal and private sources. The company has already received more than $3.5 million in nondilutive funding, including support from the National Institutes of Health, the One North Carolina Small Business Program, the North Carolina Biotechnology Center, NSF, and private-sector partners. Previous research partners include Harvard Medical School, Georgia Tech, and Virginia Tech.

By pairing George Mason’s biological and engineering strengths with Phase’s manufacturing platform, the project is positioned to advance both scientific discovery and commercialization. The result could be a more reliable path for producing the microfluidic tools needed to support the next wave of biomedical research, organ-on-a-chip development, and human-centered bio-innovation.

Creating joyful new—and therapeutic—connections through dance

Creating joyful new—and therapeutic—connections through dance Katarina Benson Thu, 06/25/2026 - 14:27

“Being in class with our participants reminds me of the pure joy of dance,” said School of Dance senior Emma Simons of her time interning with Dance for PD®.

Dance for PD is a movement-based class for people with Parkinson’s disease, which offers physical benefits to the participants and helps reduce the social isolation associated with the neurological disease. 91��’s School of Dance has offered the national program, administered by George Mason arts partner Mark Morris Dance Group, in Northern Virginia since 2021.

When Simons and fellow dance major Asiah Moore interned with Dance for PD, each took a different approach to her work, a practice encouraged by George Mason adjunct Elizabeth Spatz, a certified Dance for PD teaching artist.

Moore concentrated on increasing internal awareness of Dance for PD at George Mason, creating strategic social media content and encouraging her peers in the School of Dance to engage more robustly with the program.

She recruited fellow students to attend the classes and perform brief dance selections for class participants. After these showings, participants had the opportunity to ask the students questions about the pieces and their experiences overall.

“I wanted to combine these worlds and give the community a chance to see inside the work we do,” said Moore. “When [the participants] have a chance to see pieces beforehand, they might come to a performance, [then] they come in feeling like they’re already part of this world because they know us.”

In her work, Simons focused on external communications, building on previous interns’ research into local medical practices, retirement communities, and businesses where patients and caregivers might be looking for the resource that Dance for PD provides.

Simons made cold calls and sent out emails, aiming to bring more people to George Mason’s Fairfax Campus. But as she spent more time in class, she noticed that people’s hesitation melted inside the studio, and she decided to pivot in her approach.

“It’s so much joy to be in the room with the participants, and I knew words can’t bring people in as much as the movement itself could,” said Simons.

Simons and Moore joined forces and started reaching out to administrators at various retirement communities to organize in-person trial classes on-site. The class they offered with Westminster at Lake Ridge was very well attended.

“There were staff members who said ‘We’re just here to watch’ at the beginning of the session, but within five minutes, they were dancing and smiling and moving. It has this power for connecting people,” said School of Dance Associate Professor and George Mason alumna Shaun Boyle D’Arcy, MFA Dance '21, who helped bring the program to George Mason.

Simons and Moore graduated from George Mason in May with BFAs in dance and look forward to building on their experiences with Dance for PD. They both plan to perform professionally and are looking for companies that value community engagement and service.

Spatz said these internships can lead to jobs. “One of our former interns was hired by a company that was impressed with her [Dance for PD] experience,” said Spatz. “It’s so valuable for our students to see the different ways dance applies to people’s lives.”

Maternal obesity linked to 64% increase in childhood obesity risk

Mary Cunningham — Mon, 22 Jun 2026 15:16:36 +0000

Maternal obesity linked to 64% increase in childhood obesity risk Mary Cunningham Mon, 06/22/2026 - 11:16

The roots of childhood obesity may begin in the womb.

New research led by the 91�� College of Public Health found that children whose mothers entered pregnancy with obesity were 64% more likely to become overweight or obese by age 3. Excessive weight gain during pregnancy was associated with a 39% increase in that risk.

“Our findings suggest that childhood obesity risk may not develop in a single, uniform way, but maternal health before and during pregnancy may play a larger role than many people realize,” said study lead author Hua Min, associate professor in the Department of Health Administration and Policy.

Different pregnancy-related weight factors appeared to matter at different stages, with excess pregnancy weight gain more closely linked to infant weight and maternal obesity more strongly associated with weight later in toddlerhood.

Researchers also found that excess pregnancy weight gain was common, affecting about four in 10 mothers in the study.

Published in the International Journal of Obesity, the research is among the largest and most ethnically diverse U.S. longitudinal studies to examine how maternal weight may influence obesity risk in early childhood. Researchers tracked nearly 3,000 mother-child pairs, using data from a Northern Virginia birth cohort participating in the National Institutes of Health’s Environmental influences on Child Health Outcomes (ECHO) Program.

The George Mason research team included Michael S. Bloom of the Department of Global and Community Health, and Grace Lawrence, Alma Fuller and Kathi C. Huddleston of the School of Nursing.

Childhood obesity remains one of the most pressing health challenges in the United States. The study notes that nearly 90% of children with obesity at age 3 will continue to be overweight or obese into early adulthood. Those early patterns can carry long-term consequences, increasing risks for diabetes, cardiovascular disease, and other chronic health problems.

Researchers say the findings reinforce the importance of maternal health before and during pregnancy—not just for pregnancy outcomes, but also for a child’s long-term health trajectory. The findings also suggest that obesity risk may develop differently across populations, with patterns varying among demographic groups.

Study details

Findings were based on the First Thousand Days of Life Study, a Northern Virginia birth cohort participating in the ECHO Program, which examines how early-life experiences affect child health. George Mason was selected as an ECHO research site in 2019.

Researchers enrolled 2,899 mother-child pairs in Northern Virginia between 2012 and 2019, following families from pregnancy through age 3.

Key findings include:

Children whose mothers were obese before pregnancy were 64% more likely to be overweight or obese by age 3.

For every one-point increase in maternal pre-pregnancy body mass index (BMI), childhood overweight/obesity risk increased by about 4%.

Children whose mothers gained excessive weight during pregnancy were about 39% more likely to be overweight or obese by age 3.

About 41% of mothers in the study gained more weight during pregnancy than recommended by national guidelines.

Excess weight gain during pregnancy showed stronger links to higher weight earlier in infancy, while maternal weight before pregnancy became more strongly associated with higher child weight later in early childhood.

The associations between maternal weight factors and childhood obesity differed between Hispanic and non-Hispanic families, suggesting that obesity risk may develop differently across populations.

Key Takeaways

Maternal obesity and excessive pregnancy weight gain were both linked to higher childhood obesity risk.
Researchers found obesity risk patterns varied across developmental stages and demographic groups.
An NIH-supported George Mason study followed nearly 3,000 Northern Virginia mother-child pairs from pregnancy through age 3.

$1 million U.S. Department of Justice grant will support virtual reality training for domestic violence response Taylor Thomas Mon, 04/13/2026 - 10:05

Domestic violence 911 calls often place first responders in the midst of crisis and confusion. The scene may involve conflicting stories, visible injuries, frightened children, and little clarity about what just happened.

At 91��, researchers have secured more than $1 million in federal funding to help frontline professionals prepare for these complex moments. The grant from the U.S. Department of Justice will help fund a novel virtual reality (VR) training program to strengthen interprofessional responses to domestic violence.

Social work professors Denise Hines and Holly Matto will co-lead the one-year project in the College of Public Health, partnering with local law enforcement, domestic violence organizations, and health care providers in Northern Virginia to design and pilot the training. The team also includes social work assistant professors Michelle Hand and Anna Parisi as co-investigators, and Bethany Cieslowski, chief innovation officer for immersive technologies.

The faculty members, as well as College of Public Health Dean Melissa J. Perry, expressed gratitude to U.S. Senators Mark R. Warner and Tim Kaine of Virginia for their support of the congressional funding, and to the Department of Justice for administering the $1,026,029 award through its Byrne Justice Assistance Grants program.

“We’re thankful for the leadership and support to bring the power of virtual reality to improve health and safety,” Perry said. “Virginia will lead the way in coordinated, prevention-focused responses to domestic violence. Looking ahead, the model developed here can one day help communities across the country.”

Using technology and resources in the College of Public Health’s Lab for Immersive Technologies and Simulation, the project team will build VR case scenarios that reflect the complexities of domestic violence calls. The simulations will allow frontline professionals to practice coordinated responses and experiment with different approaches before facing similar situations in real life.

“The innovation here is bringing together professionals like law enforcement, social workers, and health care providers to co-design new VR cases that are relevant to challenges on the ground,” Matto said.

Domestic violence remains a public health and safety crisis. In Virginia alone, the statewide domestic and sexual violence hotline received more than 70,000 calls in 2023. Family and intimate partner violence accounts for roughly one-third of all homicides in the state annually. And for first responders, these calls can also be among the most volatile and unpredictable situations they encounter.

“Domestic violence calls are some of the toughest calls, but also some of the most common calls that law enforcement will come across,” said Hines, the Elisabeth Shirley Enochs Endowed Professor of Social Work. “They're often coming in at a precarious and dangerous moment.”

Five ways future health care leaders can tackle burnout in the workforce

Five ways future health care leaders can tackle burnout in the workforce Taylor Thomas Mon, 03/23/2026 - 12:17

Photo by Vladimir Fedotov via Unsplash.

The fight against widespread burnout in the health care workforce should begin with the training of future health care administrators, according to a new paper from the 91�� College of Public Health.

Published in the Journal of Health Administration Education, the paper examines how health administration programs can better prepare future leaders to address burnout by focusing on workplace factors, such as working conditions, leadership support, job design and workload, social connections, and opportunities for advancement. More than three-quarters of health care workers report feeling stressed or stretched thin, with burnout contributing to problems like higher turnover and staffing shortages that can affect patient care.

Drawing from existing research and national frameworks on workforce well-being, the principal investigator Debora Goetz Goldberg outlines several leadership strategies that can help counteract burnout, including:

Build workplaces where staff can speak up

Health care leaders must create environments where employees can report mistakes, raise concerns, and discuss safety issues without fear of punishment. Clear reporting policies, open communication, and a culture of trust are key for psychological safety.

Redesign jobs to reduce overload

Many health care roles involve long hours, heavy documentation, and clunky technology that add to daily stress. Leaders make decisions about staffing, scheduling, and tools that can either ease those pressures or make them worse.

Prevent violence and protect staff safety

Health care workers face some of the highest rates of workplace violence of any profession. Leaders can help reduce risks by establishing zero-tolerance policies, training staff to de-escalate tense situations, and putting safety measures in place before incidents occur.

Involve frontline staff in decisions

The people delivering care often know exactly where problems arise. When leaders directly involve nurses, physicians, and other staff in decisions about schedules, policies, and daily operations, the changes are more likely to succeed.

Measure and improve workforce well-being

Health care organizations routinely track patient outcomes and financial performance. Workforce well-being deserves the same attention. Leaders can measure burnout, engagement, and working conditions and use that data to steer improvements.

John Cantiello, also from George Mason's College of Public Health, and Riva Kamat from Lotus Clinician WellBeing, Inc., co-authored the paper.

$3 million NIH grant funds national study of Medicare Advantage’s benefit expansion into social supports Taylor Thomas Thu, 02/26/2026 - 07:47

Today, more than half of older Americans receive their Medicare coverage through private Medicare Advantage plans. In 2020, that program made a sweeping policy shift, allowing those plans to offer supplemental benefits beyond traditional medical care, including groceries, meal deliveries, utilities, transportation, pest control, and air filters.

Now, with an approximately $3 million R01 grant from the National Institute on Aging, 91�� health economist Jeah Jung will lead a national study to evaluate whether those benefits reduce adverse health events and improve functional outcomes.

“Health-related social needs, such as food security, housing quality, reliable transportation, and social support, are increasingly recognized as important contributors to individuals’ health,” said Jung, a professor in the Department of Health Administration and Policy. Despite the wide rollout of the new initiative to meet those needs, she said, “there is currently no information or evidence of how many people are using it, how they’re using it, and whether it’s actually bringing the intended outcomes.”

As of 2025, 55% of Medicare beneficiaries, or 34.4 million Americans, were enrolled in Medicare Advantage, the private alternative to traditional Medicare. According to Jung’s data analysis, more than 30% of Medicare Advantage plans adopted non-medical supplemental benefits by 2025. Meanwhile, she found that more than 90% of dual-eligible special needs plans—serving low-income beneficiaries enrolled in both Medicare and Medicaid—adopted the benefits.

“This is a really large-scale initiative by Medicare to address unmet social needs and see whether that helps maintain and improve beneficiaries’ health outcomes as well,” Jung said. “With an investment of this size, we want to see evidence on how it’s working and who it’s reaching so the policy can be refined in the future.”

Using secure Medicare administrative data, Jung’s five-year project will examine whether the availability of non-medical benefits is associated with changes in emergency department visits, hospitalizations, and whether patient can remain in their homes and communities rather than enter nursing homes. The study will also analyze who uses the new benefits, and whether uptake differs by demographics, such as race, ethnicity, sex, health risks, and area-level socioeconomic factors.

The project will also include contributions from Emily Ihara, professor and chair of the Department of Social Work in the College of Public Health. Researchers from Oregon Health and Science University and Dartmouth College are serving as co-investigators.

Poverty vs. Wealth: New Study Shows Biggest Buyers and Sellers of Illicit Kidneys Andrew J Schappert Wed, 02/25/2026 - 12:55

The study created a map of countries playing significant roles in the buying and selling of illicit kidneys.

An international team of researchers from 91��, Harvard University, and the University of Tokyo have used artificial intelligence to map the global underground market for illegal kidney transplants, finding that the United States consistently ranks among the world’s largest illicit importers.

The Schar School’s Naoru Koizumi led the international team that studied the illicit kidney trade.

The study, led by Naoru Koizumi, a professor at the Schar School of Policy and Government, and Schar School colleagues Olzhas Zhorayev, Zifu Wang, and Meng-Hao Li, as well as Chaowei Yang, a professor in the Department of Geography and Geoinformation Science in the College of Science.

The study appears in the International Journal of Health Geographics.

Illegal organ trafficking is widely viewed by health experts as a major but poorly measured global crisis. More than 840 million people worldwide live with chronic kidney disease, and demand for transplants far exceeds supply. On average, only about 13.5 kidney transplants occur for every 255 patients who need one, according to the study. Long waiting times—sometimes up to five years—contribute to roughly seven percent of patients dying or leaving transplant lists annually.

To better understand the hidden market, the researchers analyzed more than 50,000 news articles published over 23 years. Using large language models and retrieval-augmented generation, they built what they describe as the first global, geospatial database of illegal kidney trafficking. The system identifies reported cases and assigns roles such as seller, buyer, broker and surgery location, while also tracing financial flows.

Their analysis reveals a stark global pattern. Kidney sellers most often come from lower-income or vulnerable countries including India, China, Pakistan, Nepal, Bangladesh, and Nigeria. Buyers, by contrast, are concentrated in wealthier nations—notably Israel, the United States, the United Kingdom, Canada, and Germany.

Illegal transplant surgeries most frequently occur in India, Pakistan, China, Sri Lanka, Turkey, Thailand, and Egypt, the researchers found. Brokers often operate in the same countries as sellers but also appear commonly in Western countries.

The network is fluid: About half of the countries playing major roles shift each decade due to factors such as conflict, legal changes, enforcement intensity, and corruption. One pattern, however, has remained consistent: Over the past two decades, the United States has stayed among the top three illicit kidney buyer countries, accounting for more than 7% of documented cases.

Unlike some countries that rely on narrow supply channels, U.S.-linked cases connect to a wide range of supplier nations, including Russia, Ukraine, Kazakhstan, and India—a pattern the researchers say points to structural demand pressures within wealthy health systems.

Financial data extracted in the study underscore the imbalance in the illicit market. Buyers typically pay between $50,000 and $120,000 for a kidney, while sellers often receive less than 10% of that amount. Most profits flow to brokers and organizers.

The authors say the new database enables systematic cross-country analysis that was previously impossible because evidence was fragmented and often limited to small regional studies. Future research will examine how illegal kidney prices and trafficking patterns relate to income levels, inequality, legal frameworks, and health care access.

More broadly, the researchers argue their work demonstrates how artificial intelligence can expose hidden global systems by converting scattered media reports into structured data. They say the findings could help policymakers target enforcement, strengthen international cooperation and better protect vulnerable populations.

Printing play: A path forward for children with prosthetics

Printing play: A path forward for children with prosthetics Nathan Kahl Thu, 01/15/2026 - 08:32

A child who uses a lower-limb prosthesis faces unique challenges when it comes to activities most children take for granted, such as running and being active. Without access to a prosthetic device designed to support these movements, children may miss out not only on the simple joys of play, but also on critical opportunities for physical development during key stages of growth.

91�� researcher Quentin Sanders is part of a collaborative research team working to make high-performance prosthetic limbs more affordable, accessible, and better tailored to the needs of active children. Sanders, along with Jonathon Schofield, an associate professor at the University of California, Davis, and Garrett Melenka, an associate professor at York University, received a three-year, $500K grant from the National Science Foundation to support the project, which began in September 2025.

Most standard foot or leg prostheses are built for basic walking, not for the kind of active movement that helps children develop strength, balance, and coordination, the benefits that come from running and jumping with friends.

“This limitation can be especially challenging for children,” said Sanders, who has a joint appointment in the Department of Bioengineering and the Department of Mechanical Engineering. “Kids want to run and play. When they can’t, they’re more likely to avoid physical activities, such as sports, or even stop using their prosthesis altogether.”

Often seen in competitive events such as the Paralympic Games, running blades are curved, spring-like prosthetic feet made from carbon fiber that mimic the energy return of a biological foot. While these devices offer an alternative option to standard leg prostheses and can enable children to run, they are expensive and often inaccessible. A single running blade can cost several thousand to tens of thousands of dollars and is typically not covered by insurance because it is considered nonessential, rather than medically necessary.

Some charitable organizations help families access these devices, but demand far exceeds supply, and for growing children, one blade is rarely enough. “Kids grow quickly,” said Sanders. “As they get taller, they outgrow their prostheses, which means going through multiple blades over time.”

The research team has several goals, starting with identifying what children truly need from an activity-enabling prosthesis. The researchers are examining how motivation to be active, physical growth, and different types of movement influence prosthetic performance in everyday settings. “What do you use it for? What don’t you use it for? What do you wish you could do?” said Sanders.

The team is also analyzing how children move while using their current running blades, studying activities such as running, jumping, and changing direction to better understand the biomechanics and physical demands involved.

Finally, the team will take a close look at how today’s running blades perform under real-world demands. “We want to understand how stiff they are, how much load they can handle, and when they might fail,” said Sanders. “We can then combine that information with what kids tell us they want to do and use it to guide our 3D printing process—creating blades that are better suited for active play.”

Sanders and his collaborators are using an advanced additive manufacturing approach known as continuous-fiber 3D printing, in which carbon fibers are embedded within the printed plastic to reinforce the prosthetic structure. This method enables the creation of strong, lightweight devices that can be tailored to a child’s size, growth, and activity needs.

“By combining manufacturing, composite materials, prosthetics, design, and biomechanics, this project provides an innovative and holistic solution,” said Melenka.

The technique is already used to produce strong, lightweight components in the aerospace and automotive industries, but it has seen limited adoption in prosthetic design. This project represents one of the first efforts to apply it systematically to activity-enabling prostheses for children.

“What’s most exciting about this project is the collaboration across institutes, disciplines, and areas of expertise,” said Schofield. “We are bringing together researchers in movement mechanics, advanced materials manufacturing, and pediatric lower-limb prosthetic care. We are also incorporating the lived experience of children and families, along with clinicians who work with these patients every day.”

The work also has the potential for industry disruption, according to Sanders. “If we can show that a child’s physical measurements and movement needs can be translated into a digital model and then used to 3D print a customized prosthesis, existing prosthetic manufacturers would begin to integrate this approach into their production pipelines.”

For Sanders, the motivation goes beyond technical innovation. “I’ve always been interested in translating new technologies into real-world solutions,” he said. “Helping people with disabilities and impairments is why I got into this field in the first place.”
