Master’s Student in Public Humanities
Traci Picard is a master’s student in public humanities, a public historian and researcher. Born in Providence, Traci works on a number of public history projects here in Rhode Island. Always enthusiastic about archival boxes tagged “ephemera” and “miscellaneous,” she is constantly on the lookout for details that help tell stories about people and places, with a focus on labor, natural history, daily life and maritime medicine. Traci’s great passions include walking, urban nature and pâte de fruits: how do they get it so fruity?
Mapping Cardiovascular Disease
Ph.D. Candidate in Chemistry
Meg Shieh is a second-year Ph.D. candidate in Ming Xian’s lab in the Department of Chemistry. She graduated from Duke University in 2019 with a B.S. in chemistry with a concentration in pharmacology. Before Brown, she worked on malaria research at the Harvard T.H. Chan School of Public Health and advised on the development of serological testing for COVID-19 at the Broad Institute of MIT and Harvard. Her research interests are to develop chemical tools and cost-efficient, large-scale screening methods that can lead to a better understanding of human diseases.
An Economic Take on the Power of Thoughts
Ph.D. Candidate in Economics
Aditi Singh is in her sixth and final year of graduate studies. Her research interests focus on behavioral economics and labor economics.

Outside of research, she enjoys running, traveling and drawing cartoons.
Black Women and the Medicaid Safety Net
Ph.D. Candidate in Public Health
Kathryn Thompson is a fifth-year doctoral candidate of health services research in the School of Public Health. In her research, she leverages economic frameworks to quantitatively study how social, demographic and policy contexts shape health and disparities for women, people of color and Medicaid populations. Her research provides evidence that social identities — like race/ethnicity — and social positions — like socioeconomic status — combine in unique ways to structure health care access, health service utilization and health outcomes among vulnerable populations. Outside of Brown, Kathryn loves to travel to new and exciting places, cook, read and spend time with her family and friends.
Graduate Students Talks: Celebrating Ideas and Discoveries.
Wednesday, April 19, 2023, 4-6 p.m.
The Graduate School is delighted to host Research Matters: Celebrating New Ideas and Discoveries. Research Matters bolsters intellectual exchange among graduate students, offering a public forum for presenting research and developing presentation skills.
With short talks aimed at an interdisciplinary audience, Research Matters showcases exceptional graduate student scholarship taking place at Brown. The first Research Matters event in September 2014 was part of Brown’s 250th Anniversary Fall Celebration.
This year, we continue this tradition of celebrating the accomplishments and contributions of our graduate students. Each speaker is contributing to the academic excellence and advancement of knowledge that makes Brown unique and bold.
Our speakers range across all disciplines and stages of graduate study at Brown, from archaeology to neuroscience to economics to public health. They include students at the beginning of their studies and those about to receive their degrees. After a general call for nominations, our student speakers were selected from among 20 semifinalists to present their research today. Our event celebrates the distinctive nature of Brown graduate education.
Our speakers are eager to showcase their research with the broader community.
We hope you enjoy the talks!
