* Michele La Merrill, Assistant Professor, Environmental Toxicology – Biochemical, molecular and physiological mechanisms underlying susceptibilities to metabolic diseases evidenced in rodent models of human observational studies. These susceptibilities include environmental insults during the exquisitely sensitive developmental period, poor diet and ensuing metabolic diseases, and genetic and epigenetic predispositions.

* Lisa Miller, Professor, Anatomy/Physiology and Cell Biology: Vet Med -My research program is focused on understanding the relationship between early life environmental exposures, immunity and chronic disease. We study how mucosal and systemic immunity is established during infancy, and determine the impact of air pollutants, allergens, and infectious disease on childhood health. A major emphasis has been in the elucidation of mechanisms for immune susceptibility that lead to pediatric airways dysfunction, which may ultimately lead to generation of new diagnostics and preventative medicine.

Rebecca Schmidt, Assistant Professor, Public Health Sciences - My research goal is to advance understanding of how environmental exposures, primarily those occurring during gestation, interact with genetic susceptibility to influence neurodevelopmental outcomes for children, using a mechanistic and pathways perspective. Because nutritional factors, especially B-complex vitamins needed for one-carbon metabolism and methylation reactions, have prominent influences on gene expression and are especially important during gestation and early life, my research has largely focused their effects on neurodevelopment and risk for autism.

Jill Silverman, Assistant Professor, Psychiatry and Behavioral Sciences - My expertise is in preclinical translational evaluation of pharmacological treatments for autism spectrum disorders and our research focus encompasses behavioral phenotypes of autism in genetic mouse models, environmental toxin effects on rat behaviors, interpretation of rodent behavioral data, pharmacological treatment reversals in mouse models of autism and the development of complex rodent behavioral tasks of executive function.

Carolyn Slupsky, Professor, Departments of Nutrition and Food Science and Technology - My research is focused on understanding the impact of diet on human health from the perspective of nutrition, the gut microbiome, and host-microbial co-metabolism. We use a multi-discplinary research approach that integrates metabolomics with clinical measures, global gene expression profiles, as well as microbial community analysis to understand the intimate link between our gut microbiome, metabolism, and health.

*Ameer Taha, Assistant Professor, Food Science and Technology – My research program is directed toward understanding environmental risk factors for autism and developmental and neurodevelopmental disorders. We are examining the relationship between maternal pesticide exposure and risks of autism and neurodevelopmental delays as well as investigating the role of maternal obesity on lipidomic markers of inflammation and social behaviors in non-human primates to determine whether obesity alters maternal lipidomic markers of immunity and risk of autism-like behaviors.

Judy Van de Water, Professor, Rheum/Allergy - Immunopathology and the cellular and molecular basis of autoimmunity. Current research addresses the biological aspects of autism spectrum disorders including immune function, cellular mechanisms of immune dysregulation, and autoimmunity.
