I arrived at Idaho State University in August, 2009. I am currently an Assistant Professor in the College of Pharmacy, Department of Biomedical and Pharmaceutical Sciences. I received my B.A. in Psychology from Metropolitan State College of Denver, my M.S. in Neuropsychology from the University of Northern Colorado and my Ph.D. in Biological Psychology from the State University of New York at Albany. Following graduate school, I was a post-doctoral trainee at the Institute for Behavioral Genetics, University of Colorado, Boulder, where I remained as a Research Associate until my move to ISU.

My research interests lie in the broad area of genetics and drugs of abuse. Much of my earlier work focused on the use of inbred strains and quantitative trait locus (QTL) mapping to examine genetic influences mediating several alcohol-related phenotypes. More recently, I have returned to the area of genetic and epigenetic influences mediating differential sensitivity to the detrimental effects of prenatal alcohol exposure. We are currently using QTL mapping to identify regions on chromosomes that harbor alleles mediating susceptibility and resistance to ethanol teratogenesis. In addition, we are looking at changes in DNA methylation and gene expression at several imprinted loci following prenatal alcohol exposure. Finally, we are looking at changes in histone modifications (acetylation and methylation) following either prenatal alcohol or prenatal valproic acid exposure. Future research will begin to examine genetic influences on behavior following prenatal or early postnatal alcohol or valproic acid exposure.
