to maternal health birth outcomes, such as preterm birth. He is also interested in
understanding the relationship among macroenvironmental exposures (e.g. proximity
to major roads, proximity to greenspace) and various birth outcomes, as well.
Jessa V. Ehlinger is studying toxicology as a doctoral student in the Department of Environmental Health
Sciences. Having received her bachelors' degrees in Marine Biology and Spanish, she
is excited to now be studying the human health side of environmental health more in-depth.
Through her thesis work, Jessa is taking an epigenetics approach to studying the effects
of childhood mercury exposure on neurological outcomes in children and adolescents.
Jessa utilizes both in vitro models of human neurodevelopment as well as epidemiological
data through the ELEMENT (Early Life Exposures in Mexico to ENvironmental Toxicants)
birth cohort. When Jessa is not in the lab, she enjoys playing her cello, SCUBA diving,
cooking, hiking, and ignoring reminders from DuoLingo telling her to actually practice
French.

degree in Toxicology in the department of Environmental Health Sciences. She is broadly
interested in the effects of environmental toxicant and pesticide exposure on health,
particularly in underserved, rural, and urban communities disproportionately affected
by environmental poisoning. She is excited to work with Dr. Colacino and Dr. Bakulski
on a project concerning the effects of lead exposure on the development of neurodegenerative
disease. In terms of clinical interests, she hopes to pursue residency in either Emergency
Medicine or Family Medicine, because of the connections these fields have to rural
health and toxicology. In her free time, she enjoys listening to/playing music, reading,
spending time with cats, and doing anything outdoors.
Edith Mercado, BS, is a first year doctoral student in the Environmental Health Sciences School
of Public Health. She is interested in assessing human exposure to chemicals (metals,
pesticides, PFAS, & tobacco exposures) and how they play a major role in human health.
More specifically, how the mechanisms and outcomes of these chemicals interact in
the human body. In addition, she is interested in how environmental injustice plays
a role in marginalized communities and their interaction with these types chemicals
impacting their well being.
Seonyoung (Shannon) Park, MPH, is a doctoral student of Environmental Health Sciences at the University of
Michigan School of Public Health. Before coming to the University of Michigan she
completed a master's program at Columbia University (2019-2021), as a Fulbright scholar,
studying Environmental Health Sciences with Applied Biostatistics and Public Health
Data Science Specialization. Before that, she received a BS in chemistry and nanomaterial
engineering from the Ulsan National Institute of Science and Technology, Korea (2014-2019).
Her research is focused on environmental exposure such as exposure to endocrine disrupting
chemicals (EDCs) or air pollution and their impact on children's health. She is particularly
interested in identifying the critical period for this exposure and dimorphism of
etiology by sex.

the effects of these gene-toxicant interactions in utero. Jennifer hopes to elucidate
the various barriers that may exist amongst different populations because of epigenetic
setbacks that have occurred as a result non-consensual toxic exposure. She seeks to
use her research as a tool to advocate for widespread policy change in urban and rural
areas, and other locations of uniquely high toxic exposure and poor health outcomes.
