This work was cited as a model approach that may allow for directly assessing the role of early nutritional and environmental exposures in human adult disease.

Jackie GoodrichJackie Goodrich, PhD, Research Assistant Professor, Projects 2 & 3
Jackie Goodrich is a Research Assistant Professor in Environmental Health Sciences and her current research focus is environmental epidemiology and epigenomics with the goal of identifying epigenetically labile genomic regions that contribute to environmentally-induced disease susceptibility at various life-stages (in utero, early childhood, and adulthood). She also has a keen interest in the impact of environmental exposures, particularly to heavy metals, on cardiovascular and metabolic health outcomes. She serves as the Epigenetics Lab Coordinator for the P01. In this center, she investigates the influence of in utero exposures to environmental chemicals (e.g., lead, phthalates) on DNA methylation at birth and in early adolescence and evaluate epigenetic drift over time in a longitudinal birth cohort. She integrates data on exposures, DNA methylation, and health outcomes to determine whether modification to DNA methylation patterns is a mechanism linking prenatal exposures to altered growth and development and ultimately adult disease (e.g., metabolic syndrome). Our research team addresses similar research questions in the agouti mouse model, and she has contributed epigenetic expertise to this study.

Joe KochmanskiJoe Kochmanski, MPH, Doctoral Candidate, Project 3
Joe Kochmanski is a doctoral candidate in the Environmental Health Sciences department. His research focuses on the combined effects of age, endocrine disrupting chemicals (EDCs), diet, and physical activity on the epigenome. More specifically, his dissertation explores whether perinatal alterations in diet, physical activity, or EDC exposure modify age-related changes in DNA methylation. The goal of this work is to determine whether perinatal exposure to combined environmental factors changes the trajectory of epigenetic marks throughout the lifecourse, thereby altering susceptibility to metabolic disorders. Joe is involved in Project 3 of the UM-CEHC, investigating the longitudinal effects of BPA exposure on epigenetic marks in genes related to growth, metabolism, and development.

Lisa MarchlewiczLisa Marchlewicz, PhD, RD, Project 3
Lisa Marchlewicz is successfully defended her doctoral dissertation that integrates her interests in diet, metabolism, and environmental exposures through toxicologic and endocrine pathways. Her dissertation research explores the potential for exposure to endocrine disrupting chemicals (bisphenol A, BPA) and dietary fat (Western vs. Mediterranean consumption patterns) of mothers during pregnancy to impact the hepatic lipid metabolism and oxidative stress in perinatally exposed offspring. The goal is to better understand the interactions between multiple simultaneous perinatal exposures, which mimic the common human experience, to determine the ability of these exposure mixtures to induce metabolic programming in infants that may alter their susceptibility to metabolic diseases (e.g. obesity, type 2 diabetes, metabolic syndrome) throughout their adult life. In the P01 UM CEHC, Lisa spearheaded Aim 1 of the animal project (Project 3), coordinating the 14 month longitudinal agouti mouse study investigating the potential for perinatal BPA and high fat diet (HFD) to alter offspring lipid metabolism, insulin sensitivity, hepatic steatosis, and oxidative stress from birth through adulthood. Lisa mentors a doctoral student, two masters students and an undergrad, who are assisting with longitudinal laboratory measures for the study.
