  • Associate Professor of Environmental Health Sciences
Profile Headshot


Dr. Re is a neuroscientist focused on investigating environmental risk factors and mechanisms for neurodegenerative diseases. The overarching goal of Dr. Re's research is to make an impact in therapy and prevention of amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases through innovative and rigorously designed mechanistic and biomarker studies. Since she started her faculty appointment, she has developed a novel line of animal- and human model-based experimental research linking environmental exposures and in particular metals and pesticides to the late-onset paralytic disorder ALS. Dr. Re's work is at the forefront of complex and poorly understood gene-environment (GxE) interactions in the etiology of ALS and, more recently, Parkinson's disease. Overall, her independent research to date has primarily focused on five complementary topics: 1) Novel therapeutic candidates for ALS; 2) Novel biomarkers of environmental exposure and disease progression in ALS; 3) Genuine GxE interactions in ALS; 4) Molecular and cellular mechanisms underlying neuromuscular aging; and 5) Neurotoxic risks from exposure to electronic cigarette aerosol. Dr. Re's research work is supported by funding from notably the NIEHS, NIA, CDC/ATSDR, and DOD.

Since 2018, Dr. Re is the Director of the "Fundamentals of Toxicology for Health-Related Disciplines" course that aims at introducing the basic concepts of toxicology to students from multiple health-related fields (epidemiologists, policy makers, etc.) who are interested in public health and the environmental basis of human disease. She is also the Director of a 2-day professional development workshop the "PI Crash Course: Leadership and Management Skills for Future or New Lab Leaders" as part of her efforts to cultivate the next generation of scientific leaders.

Global Health Activities

CROSS-NEUROD 778003 European Program , Italy and Greece: Dr. Re is the US coordinator of the CROSS-NEUROD program that consolidates research partnerships through staff exchanges and networking activities between 3 European research organizations, two of them from Italy, one from Greece and one partner, USA. The project is based on a 4-year joint research exchange program for short periods. The research goals of the program are: 1) the development of integrative in vitro models of 3D disease (mini-brains, mini-spinal cords and motor units) to elucidate the cellular and molecular pathways common to neurodegenerative diseases; 2) the validation in animal models of the identified therapeutic targets.
