Pereira said solar flare prediction is key because really intense solar flares are often associated with coronal mass ejections (CMEs), which in turn can cause geomagnetic storms, carry radiation, and significantly contribute to space weather.

“CMEs, geomagnetic storms, and solar radiation can affect our satellites if we are unprepared. These events can also knock out our GPS or power grids on rare occasions,” he said. “What we really want is to figure out what is causing solar flares. We have some suspicions, but maybe machine learning techniques can find something we didn’t.”

There are already some prediction models in place now, but Pereira’s research is trying to push past the current “bottleneck” in the research. His work is not only trying to confirm previous techniques but also testing out a new one.

Pereira is the recipient of a Graduate Inclusion and Access scholarship, which works to enhance the diversity of the graduate student community at George Mason by providing scholarships for first-generation doctoral students who have been historically underrepresented within their doctoral field of study. The scholarship provides funding and an opportunities to become involved in the graduate community through special events each semester.

“The grade requirements [for the scholarship] are a little higher than those of my fellow grad students, but I think the hard work is rewarding and will help me stay on track to finish within the five years.”

Pereira came to George Mason after completing his undergraduate degree in physics and astronomy at University of Maryland (UMD), College Park. He initially became interested in space weather his freshman year at UMD. “I had an introductory electricity and magnetism course. It seemed interesting to me to learn about solar wind, the types of phenomena that occur in space, and how the physics of it all actually impacts us on Earth.”

In his junior and senior years, Pereira worked on space weather research with his then-advisor Surjalal Sharma and became interested in continuing that research in his graduate studies. He then visited George Mason, where he met with his current advisor Jie Zhang of the Department of Physics and Astronomy. “[Zhang] helped me set up the possibilities for what can be done in this field, and he had the idea for the project that I'm working on now,” Pereira said.

On the same visit, Pereira had the opportunity to meet with graduate students who let him know that the PhD program wasn’t easy, but he would have the support he needed. He was able to see the graduate student culture with his own eyes, which helped him feel like he could belong at George Mason.

Pereira offers advice to other students considering PhD programs. “You should talk to as many people as possible—that can help guide your decision process. Some people have good experiences, some people have bad experiences, and they’re all valid. Everyone’s on their own path.”

“Pereira’s passion to research and commitment to his doctoral program are inspiring,” said Laurence Bray, senior associate provost for graduate education. “He represents the Mason Nation at heart by designing his own path to success with strength and resilience.”

Pereira’s enthusiasm for his research continues. “The reason I do physics is because I like figuring out how things work. And it's not necessarily easy, but in the end, when you have that ‘aha moment,’ it really is rewarding,” he said.

Kaya, an assistant professor in George Mason’s School of Education, and his collaborators—Hasan Deniz of University of Nevada, Las Vegas; Ezgi Yesilyurt of Weber State University; and Refika Turgut of University of South Carolina—have been awarded a $1 million grant from the National Science Foundation (NSF) “Computer Science for All” program for their project, “Cultivating Artificial Intelligence Literacy through Linguistically Inclusive Integrated Elementary Curriculum via Educational Robotics.”

“Over the years, I have seen firsthand how robotics can captivate and inspire students, making complex STEM concepts accessible and more engaging,” said Kaya. “Students gain insight into how AI systems work and develop a deeper understanding of the power of AI, which promotes foundational AI literacy.”

Approximately 600 elementary students in grades 4 and 5 from schools serving underrepresented populations in Clark County, Nevada, will participate in this study. The goal of this project is to provide the students with hands-on learning opportunities that will allow them to develop an understanding of AI and its application in science and technology.

The study will also offer professional development to 25 in-service educators to equip them with the foundational knowledge of AI and machine learning needed to teach an AI-integrated STEM curriculum.

Kaya emphasized that it is essential for young learners to acquire a level of AI literacy that includes an understanding of how AI algorithms work, how AI applications are developed, and how they can be used responsibly and creatively. He hopes that by being exposed to AI and machine learning at an early age, students will develop skills that may lead them to pursue careers in STEM.

“This project is about opening doors to AI literacy for young students, especially those from multilingual backgrounds who may not see themselves represented in tech fields,” said Kaya, who grew up in Turkiye and began learning English in middle school.

After working with multilingual learners in Title I schools in Arizona, Kaya discovered that his perspective as someone who has navigated education in multiple languages gave him insight into serving this population of students effectively.

“By integrating AI and robotics early on, we are providing a foundation in STEM that not only builds skills but instills a belief in students that they can be part of AI-intensive fields,” he said.

Educational tools, including Birdbrain Technologies’ Hummingbird Robotics®, Teachable Machine, and Snap!, a visual block-based programming environment, will be used in this study. Students will be tasked with designing automated solutions to real-world challenges that exist in their home communities, such as how to make smart homes more energy-efficient or how to develop farming robots capable of harvesting strawberries. Kaya said that projects like these will allow the students to apply AI concepts in ways that they will find more culturally relevant and meaningful.

The study will also promote the responsible and ethical use of AI by asking students to engage in critical thinking regarding the broader societal impact of AI and how bias can affect AI algorithm outputs.

Teachers using the AI-integrated curricular resources developed under this project will be able to incorporate them into their existing curricula.

“Our curriculum is designed to be flexible and integrative. By combining AI, engineering, language arts, and science into integrated lessons, teachers can address multiple subjects within a single lesson, making the most of limited classroom time,” said Kaya.

The importance of teaching the principles of AI and machine learning at an early age continues to gain traction in K-12 computer science education. Kaya notes that organizations such as the International Society for Technology in Education and Computer Science Teachers Association (CSTA) are responding with programs such as Teach AI. In addition, CSTA is updating its standards, scheduled for release in 2026, to incorporate machine learning and AI.

At the state level, Virginia’s recent updates to the Computer Science Standards of Learning (SOLs) include requirements for machine learning, further underscoring the need to prepare students in this field.

It is these changes in the field of computer science education that influenced Kaya’s decision to pursue a second master’s degree—this one in machine learning—at George Mason. “Even though I have a CS background, I recognized that machine learning and AI are becoming crucial parts of CS education,” he said. “To better serve the needs of future teachers and K-12 students, I decided to further my own education in this rapidly evolving field.”

With this project, Kaya said the goal is to equip teachers to bring AI and robotics into their classrooms with confidence, even if they do not have a technical background. “By providing practical training and readily available materials, we hope to create a ripple effect where teachers inspire their students and make AI education a reality in their classrooms,” Kaya said.

��AV has been awarded funding from the National Institutes of Health (NIH) through its Artificial Intelligence/Machine Learning Consortium to Advance Health Equity and Researcher Diversity (AIM-AHEAD) program.

This initiative encourages more people from historically underrepresented groups in researching and developing of artificial intelligence (AI) and machine learning (ML) models. AIM-AHEAD aims to leverage the growing volume of data generated through electronic health records (EHR) and other biomedical research to address health disparities and inequities.

The newly funded project, led by Janusz Wojtusiak, builds upon the Equitable and Accessible Software for Injury Detection (EAS-ID) initiative aimed at building artificial intelligence tools for collecting, assessing and analyzing injury data. The new funding specifically addresses the problem of measuring equity and quality of imaging documentation.

In addition to Wojtusiak, an interdisciplinary research team comprising Katherine Scafide and David Lattanzi is joined by Health Informatics Assistant Professor Eman Elashkar, Research Assistant Professor Jesse Kirkpatrick, who is also the acting director of the Institute for Philosophy and Public Policy, and Amin Nayebi Nodoushan, a postdoctoral researcher at Mason.

Their research focuses on using AI methods combined with Alternate Light Sources (ALS) to improve bruise detection, addressing visibility issues for individuals with darker skin tones who often encounter challenges in accurately assessing injuries sustained from violence.

Current literature highlights that skin color significantly influences the accuracy of AI-based tools in healthcare. Studies have documented disparities in the performance of medical devices, such as pulse oximeters and smartwatches, which frequently yield inaccurate readings for individuals with darker skin. These discrepancies can lead to delays in critical medical interventions, exacerbating existing health disparities.

The proposed research will focus specifically on bruises, the most common type of soft tissue injury experienced by victims of intimate partner violence (IPV). Statistics indicate that approximately one in three people in the U.S. have experienced IPV, with racial minorities reporting disproportionately higher rates. Survivors with darker skin tones have noted that their bruises are often invisible, resulting in significant delays in seeking necessary medical care.

Leveraging the innovative use of ALS, the George Mason research team has demonstrated marked improvement in bruise visibility across diverse skin tones. The team aims to develop methods that ensure that AI-based tools provide equitable and unbiased detection and characterization of injuries. This will involve creating combined technical-ethical metrics to assess the performance of these tools across different skin tones. Engaging diverse stakeholders, including clinicians, forensic nurses, and community representatives, will be essential in the development process to align with ethical practices in AI.

The research team’s two primary aims are to develop metrics that assess equity in AI tools and apply these metrics to improve bruise detection models. They have already collected a substantial dataset of bruise images taken under various lighting conditions, which will be utilized to enhance the AI models’ performance. The interdisciplinary nature of the research team, comprising informaticians, engineers, clinicians, and ethicists, ensures a comprehensive approach to tackling these complex issues.

In alignment with AIM-AHEAD’s goals, this research initiative promises to contribute significantly to addressing health inequities and enhancing the capabilities of AI in healthcare. By focusing on the specific needs of underrepresented communities, the George Mason research team is paving the way for more equitable health care solutions, ultimately aiming to improve the accuracy and efficacy of injury assessments across diverse populations.

This project is led by George Mason’s College of Public Health in collaboration with the College of Engineering and Computing. More information on the project can be found at bruise.gmu.edu.

New research utilizes machine learning to address social isolation among alzheimer’s caregivers mthomp7 Thu, 10/10/2024 - 13:22

A new study from the College of Public Health at ��AV, led by Professor Janusz Wojtusiak and Health Services Research doctoral candidate Ghaida Alsadah, explores the use of machine learning to predict social isolation among caregivers of individuals with Alzheimer’s disease and related disorders.

This research, which has been selected for funding by the Commonwealth of Virginia's Alzheimer's and Related Diseases Research Award Fund (ARDRAF), marks a significant advance in leveraging artificial intelligence (AI) to address a critical public health issue.

Professor Janusz Wojtusiak uses machine learning to predict social isolation among caregivers of individuals with Alzheimer’s disease and related disorders.

Alsadah has played a pivotal role in this study, contributing her expertise as a doctoral candidate to develop and refine machine learning models. These models analyze data from the Health and Retirement Study (HRS), National Health and Aging Trends Study (NHATS), and Behavioral Risk Factor Surveillance System (BRFSS) to identify and predict social isolation trajectories among caregivers. The study’s key finding is that AI-driven methods offer a novel approach to detecting social isolation, potentially leading to targeted interventions.

“This research is groundbreaking in its application of machine learning to predict social isolation among caregivers, an area previously underexplored,” said Wojtusiak. “The potential to develop AI-based interventions could significantly enhance the well-being of caregivers who often face profound social and emotional challenges.”

The study aims to construct predictive models for social isolation, adapt them for Medicare claims data, and simulate their application across large populations. The goal is to create a framework for AI-based interventions to address loneliness among caregivers effectively.

The innovation of this work lies in its use of machine learning to analyze and predict social isolation—a new approach with the potential to transform current understanding and interventions. Wojtusiak and Alsadah’s research is set to significantly impact health informatics and caregiver support. “Predicting Social Isolation Among Alzheimer’s Caregivers Using Machine Learning” will be published in an upcoming issue of a leading health informatics journal, emphasizing the importance of innovative approaches to complex public health challenges.

Additional contributors include College of Public Health alumna Mary Louise Pomeroy, a postdoctoral research fellow at Johns Hopkins University, who provided valuable expertise on social isolation and relevant datasets.

Amarda Shehu

Padmanabhan Seshaiyer

Amarda Shehu, a professor of computer science and associate dean in the College of Engineering and Computing, and Padhu Seshaiyer, a professor of mathematical sciences and the former associate dean for academic affairs for the College of Science, were named to the State Council of Higher Education for Virginia (SCHEV) EO30 task force, prompted by Executive Order (EO) 30 by Virginia Governor Glenn Youngkin.

Both Shehu and Seshaiyer acknowledge that this is a timely and important initiative by SCHEV, and they are excited that ��AV is an integral part of this process, supporting SCHEV, and by extension, institutes of education across the commonwealth.

The EO states that it “recognizes the dual nature—both the opportunities and risks—of this developing technology in education. K-12 schools and postsecondary institutions must embrace innovation, experimentation, and new educational opportunities for students as well as ensure appropriate guardrails and necessary constraints exist to safeguard individual data privacy and mitigate discriminatory outcomes.”

SCHEV leaders chose Shehu and Seshaiyer for the task force because of their longstanding work and leadership in artificial intelligence (AI), STEM, and education; both admit there is a lot to consider around AI, and they are glad that Virginia is putting forth this effort.

Shehu said a broad conception of AI is necessary. “We need to think a little bit more holistically regarding the different opportunities and potential risks with regards to integrating AI in education. What kind of guidelines should we have for universities and for community colleges, not just for educators, but also for all the different organizations that they work with across Virginia.”

Seshaiyer explained that the task force has broad representation. “While we talk about promoting innovation and economic growth, there's also this whole aspect of ethical boundaries and considerations in AI development and deployment," he said. "It requires government, industry, and academia coming together to understand AI research, workforce development, and responsible AI.”

Shehu said the task force’s work and function are evolving. “A lot of the meetings I imagine will be thought experiments and the members feeding off one another based on our expertise. Some of us may be more positioned toward exciting applications, while some will want to caution, ‘Hey, hold on a second—you can't really do acquisition like this because you have to go through so many regulatory processes.’”

Shehu said they had been asked to consider and build on examples and guidelines from states, countries, and regions to be forward-thinking in their approach. One approach would be for the task force to categorize AI applications that are definitely a no, some that are yes, and some that still exist in a gray area.

Seshaiyer has encouraged students to experiment with AI in assignments. Photo provided

“For instance, AI assessing your emotions and your reactions and anything like that used for surveillance—that's a ‘no’ unless in situations of national security,” she said. “Consider personalized learning settings that are popping up where you might see clear value for an AI agent that sits and monitors you to read facial features so it can figure out if I'm confused or if I'm understanding. But for the task force, that’s a no, because that is surveillance. Please keep in mind we are thinking about children and students, a highly vulnerable population.”

Seshaiyer said, “For higher ed we have K-12 on one side, and workforce on the other side, so we are theoretically coming up with all sorts of academic ideas about AI and its implications. We test it on a nice cookbook problem, while the workforce side is looking at it from a business perspective, and K-12 is of course thinking of the learning implications. This is an example of having the tension in understanding AI implications by different stakeholders between impact, thoughtfulness, and speed.”

Those dealing with children have multiple considerations, he added. “So, the question for the principal or the Chief Information Technology Officer of the school system is, ‘How do I navigate this space? Which software is feasible, appropriate and at the right price point? Is it safe to use and are there any backdoors in terms of data privacy?’ There are these really practical questions for which they don't have answers because nothing is formally written, but they also don't quite know how to evaluate AI and its implications even if there are answers of how to actually evaluate it.”

The recommendations and guidance provided will impact rank-and-file faculty members, but also must be understood by deans, presidents, and provosts in higher ed, the faculty members said.

Seshaiyer said, “This could have impact across the curriculum. Should I change the content or the way I teach a class? Do I need to go back because maybe I was doing it all wrong or I thought I was doing it right? So, if I were to put my money into the recommendations, it would be training, training, training,”

The task force members are currently working on creating a draft of emergent themes on opportunities, issues, and executive order responsibilities. They have not yet been told what their timeframe is or the expected length of service.

��AV Receives $4.85 Million Gift to Increase Intimate Partner Violence Detection and Reporting

FAIRFAX, VA (March 5, 2024) – ��AV today announced an anonymous $4.85 million gift to advance groundbreaking research on bruise and injury detection for individuals who experience interpersonal violence. The funding will help develop new tools in imaging technology using a light source that is five times better than white light for identifying and visualizing bruising across all skin tones for use by forensic nurses, social service providers, and law enforcement.

“This single largest gift to support research in the College of Public Health’s history underscores Mason faculty’s leadership in life-changing work affecting those who experience interpersonal violence,” said Melissa J. Perry, Dean of the College of Public Health. “A gift of this magnitude brings transformative resources to Mason’s cross-disciplinary research and collaborative approach that takes ground-breaking research to new heights with the potential for greater use and impact.”

Mason’s acclaimed interdisciplinary research in using Alternate Light Sources for bruise detection, as featured on NBC Nightly News, is led by Katherine Scafide, David Lattanzi, and Janusz Wojtusiak. The funding will expand the team’s bruise detection system that leverages artificial intelligence (AI), imaging and light technologies, forensic reports, and clinical expertise to increase data collection and access to care for trauma victims. The technology can be used across all skin tones and responds to deficits in the identification of physical injuries particularly among people with darker skin tones.

Filmmaker and humanitarian Angelina Jolie examines bruising using alternate light.

"By improving documentation of physical trauma, we hope to address disparities in clinical care which can lead to improved healthcare for all as well as legal recourse for all survivors of violence," said Scafide, forensic nurse, research leader, and Associate Professor of Nursing in Mason’s College of Public Health. “This gift expands Mason’s leadership in developing new technologies to empower vulnerable communities.”

One in 3 women worldwide experience physical trauma at the hands of an intimate partner or stranger. In the United States, over 10 million women and men grapple with intimate partner violence each year. Among domestic violence survivors, bruises and soft tissue trauma are the most reported injuries. When injuries are accurately documented, survivors are more likely to participate in the criminal justice process, according to recent studies on interpersonal violence and reporting. In addition, family and partner violence and elder abuse can lead to a host of other public health issues such as infectious and noninfectious diseases, mental health trauma, and reproductive health problems.

"A vital piece to success is ensuring that any AI tool has access to in-depth data from all skin tones and skin characteristics alongside human expert analysis,” said Lattanzi, associate professor in the Sid and Reva Dewberry Department of Civil, Environmental, and Infrastructure Engineering in the College of Engineering and Computing.

Supporters working on ending domestic violence commended the announcement.

Ruth Glenn, President of Survivor Justice Action, applauds the groundbreaking work led by Dr. Katherine Scafide at ��AV, harnessing alternate light source (ALS) technology to support and uplift the needs of domestic violence survivors. “In a nation where domestic violence disproportionately impacts communities of color, this innovative research holds immense promise. By prioritizing inclusivity and recognizing the unique challenges faced by survivors with darker skin tones, Scafide's research aligns seamlessly with our vision to end domestic violence in our lifetime. Continued research on this technology not only has the potential to revolutionize the identification of bruising in diverse populations but also signifies a vital step toward justice and empowerment for those who have long been marginalized. Survivor Justice Action stands firmly in support of initiatives that demand systems change and establish resources for survivors and advocates.”

“The Scafide team’s research and findings are revolutionizing medical forensic examinations. The ability for medical professionals to visualize and identify previously ‘invisible’ injury substantively advances quality medical assessment and patient care. Visibility and documentation of trauma/ injury provide valuable forensic corroboration for law enforcement and the courts to hold offenders accountable,” said Ann Burdges, CEO of End Violence Against Women International.

This project is led by Mason’s College of Public Health in collaboration with the College of Engineering and Computing. More information on the study can be found at bruise.gmu.edu.
