Current PhD Students

Giselle Bellia is a PhD Student at the Yale School of Public Health, following her graduation from the department of Environmental Health Sciences MPH program. She holds a BA in psychology from Seton Hall University. She is interested in psychiatric epidemiology, with a specific interest in environmental influences on fetal and childhood neurodevelopment. She also enjoys learning about innovative research and statistical methodologies to explore these interests.

Francisco is a first-year Ph.D. student in the Department of Environmental Health Sciences at the Yale School of Public Health and an NSF Graduate Research Fellow. He holds a Bachelor of Science in Biology from the University of Puerto Rico, Rio Piedras. Francisco has a background in Ecology, studying climate through the use of tree rings. His research interests meet in the health effects of climate variability, particularly extreme weather events.

Chengyi Lin is a Ph.D. student in the Department of Environmental Health Sciences at the Yale School of Public Health. She is interested in the health effects of air pollution. Her current project evaluates the association between ozone and mortality.

Athina Lisgara is a first-year Ph.D. student in Environmental Health Sciences at Yale School of Public Health. She earned her integrated Master's Degree in Environmental Engineering from University of Patras in Greece, focusing on Environmental Toxicology. For her Ph.D., she uses MALDI imaging mass spectrometry (MALDI MSI) for bottom-up proteomics to study neurodegenerative diseases in the brain. She also explores liver disease by developing novel metabolomic workflows coupled with MALDI MSI and applying deep learning techniques. Athina actively volunteers with Greek Women in STEM and the Yale Undergraduate Mentorship Program.

PhD candidate in EHS at YSPH MPH in CDE at YSPH, class of 2021

Jingyuan is a fourth-year PhD student in the Department of Environmental Health Sciences. She holds a master's degree in Social and Behavioral Sciences from YSPH and completed her undergraduate studies in Psychology at UC, San Diego. Her current research interests center around the early origins of neuropsychiatric disorders and possible transmission of disease risks across multiple generations due to adverse intrauterine exposures.

Jean is a PhD student in the Environmental Health Sciences department at YSPH. As a member of the Pollitt Lab, Jean is interested in measuring personal exposure to complex environmental pollutants using the Fresh Air wristband and understanding how these exposures can adversely affect human health. She is also interested in learning about statistical approaches for analyzing multivariate, high-dimensional non-parametric data. Jean earned her MPH from YSPH in 2019. Before coming back, she worked as an environmental health scientist at an environmental and risk sciences consulting firm based in Boston. Her work involved evaluating epidemiology and toxicology literature, as well as analyzing exposure assessment data in support of causation analyses in litigation and human health risk assessments.
