Past Team Members
Futu graduated with a Ph.D. in Population Health Sciences (Environmental Epidemiology track) from Harvard University in May 2023 and joined the University of Southern California as a postdoctoral scholar. Her dissertation explored household, housing, and neighborhood factors exacerbating or sustaining environmental health disparities. Using HOME Study resources, she explored 1) household-level joint exposure disparities to both environmental and social stressors and 2) household and influential behavioral factors of residential air exchange rates. Her epidemiology research looked at effect modification by structural air exchange rates for the association between short-term ambient air pollution and mortality risks. She plans to continue studying (on the west coast) how location/neighborhood context shapes one's opportunities and risks. Besides that, she believes that data has a strong storytelling power, not only in scientific publications but also in community-based languages. Had Futu not pursued an academic life, she would like to open a bakery and be a weekend swimming coach.
Ashley Gripper received her PhD in the Population Health Sciences Program and Environmental Health Department at the Harvard T.H. Chan School of Public Health. Using epidemiologic, spatial, and quantitative methods, Ashley’s work explored the mental, spiritual, and social health impacts of urban agriculture on farmers in Philadelphia. She has been active in food justice and land sovereignty movements for almost a decade and as a result, has established connections and built meaningful relationships with urban and rural growers from around the country. Ashley has particular experience in creating and fostering urban design that has explicit public health impacts and benefits. Specifically, she has consulted with architectural firms and New York City Housing Authority to design spaces conducive to healthy eating and agriculture in public housing. Through a national fellowship with the Robert Wood Johnson Foundation’s Health Policy Research Scholars, Ashley also learned to translate research into policy that will improve community health. Now, Dr. Ashley Gripper is an assistant professor in the Department of Community Health and Prevention and an affiliate of The Ubuntu Center on Racism, Global Movements, and Population Health Equity. She has a secondary appointment in the Department of Environmental and Occupational Health.
