The once controversial idea that parental experiences, such as stress or diet, can shape the physiology and behavior of their offspring via epigenetic mechanisms has become an active area of research. Dr. Mathieu Wimmer studies the influence of drug abuse in fathers (sires) on future generations. His research program combines animal models of drug addiction and memory formation with molecular biology techniques to investigate the impact of paternal drug taking on drug-related behaviors and memory formation in progeny.
Dr. Wimmer is also interested in epigenetic remodeling events in the brain that underlie these inherited changes in behavior. Dr. Wimmer received his PhD from the University of Pennsylvania under the mentorship of Dr. Ted Abel. His postdoctoral training under the guidance of Dr. Chris Pierce at Penn focused on the transgenerational epigenetics of cocaine addiction. Dr. Wimmer’s research is funded by the National Institute on Drug Abuse.
Reza Karbalaei, PhD.
Reza graduated from Tehran University in 2005 with a B.S. in Cell and Molecular Biology. He earned an M.S in Molecular Biology from the national institute of genetic engineering and biotechnology (NIGEB), where his work focused on cloning new genes in the B. subtilis genome. His Ph.D. in Medical Proteomics from Shahid Beheshti University of Medical Sciences focused on the meta-analysis of available high-throughput data on Alzheimer's disease. In the Wimmer lab, Reza has been developing bioinformatic analytical pipelines for large sequencing data sets. His projects are aimed at delineating the molecular signatures associated with chronic drug exposure in reward-related brain regions. He is also continuing to purse meta-analyses of existing data sets related to addiction-like behaviors in rodents and chronic drug use in humans.
Dana Zeid, PhD.
Dana earned her B.A. in Psychology from Marshall University in 2016. Under the mentorship of Dr. Thomas Gould, she received her Ph.D. in Biobehavioral Health from Penn State University in the summer of 2021. Her graduate research focused broadly on genomic, neurobiological and behavioral underpinnings of learning and addiction in rodent models. Dana joined the Wimmer lab in the Fall of 2021. Her current research interests include mechanisms underlying multi- and transgenerational inheritance of drug addiction phenotypes, as well as the development and study of rodent behavioral paradigms.
Beth earned her B.S. in Neuroscience and Behavior from the University of New Hampshire in 2015. While at UNH, she studied thalamic nuclei and their influence in flexible goal-oriented behavior. She then pursued her Ph.D. in Dr. Kyle Smith's lab at Dartmouth College. Her graduate work focused on contributions of ventral pallidum and nucleus accumbens in cue-driven motivation and behavioral phenotypes. She continued as a postdoc for a year in the Smith Lab using optogenetic and chemogenetic techniques to manipulate motivated behaviors. In the Wimmer lab, Beth is looking forward to exploring the multi- and transgenerational impact of drugs of abuse leveraging a combination of behavioral and molecular approaches.
