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 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 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.

Joanna graduated from the University of Massachusetts Boston with a B.S. in Biology in May of 2021. While at the University of Massachusetts Boston, Joanna was a research assistant in Dr. S. Tiffany Donaldson's lab where she studied environmental enrichment as a treatment for hypoxic-ischemic encephalopathy. She also contributed to work concerning the effects of amphetamine exposure in adolescent rats. She joined the Wimmer lab as a PhD student in fall 2021 and hopes to investigate the epigenetics of chronic drug use and how drug addiction may contribute to cognitive deficits. Outside of the lab, Joanna likes making and listening to music, fitness, and reading comics.

Paris graduated from the Florida Institute of Technology with a B.S in Psychology and specialization in Neuropsychology. While completing his undergraduate degree, his research under the tutelage of Dr. Webbe focused on concussion testing in patients using an objective Virtual Reality system (NVIT). Paris then joined Drs. Mihailidis and Khan's laboratories at the University of Toronto where he helped develop and Artificial Intelligence Response System for fall detection. Paris joined the Wimmer lab as a PhD student in the Fall 0f 2021. He plans to investigate the epigenetic processes contributing to substance abuse and addiction-related behaviors.  In his free time, Paris enjoys listening to musing, working on his vacation rental business and traveling. 

Genesis graduated from Lawrence University with a B.A. in Neuroscience in June of 2021. She relocated to Germany where she worked as a research assistant in Dr. Vanessa Stempel’s lab at the Max Planck Institute for Brain Research investigating sex and estrous-specific changes in the periaqueductal gray (PAG). She joined the Wimmer lab as a PhD student in the fall of 2024. She is interested in exploring how the estrous cycle may modulate addiction-related neural plasticity. In her free time she enjoys cooking, attending music events, and traveling. 

I am from Puerto Rico and graduated from Norwich University with a B.A. in Neuroscience and Minors in Biology and Psychology in April of 2023. I joined the Wimmer lab as a laboratory technician in August 2023. I’m excited to participate in the research dedicated to the effects of opioids on memory and addiction and learn the new things and experiences that comes with being in a research lab. In the future, I have plans on attending medical school and pursuing a career as a physician.

Madeline is pursuing a BA in Psychology in the College of Liberal Arts with a minor in Cognitive Neuroscience and Biology (class of 2024). She joined the Wimmer lab in summer of 2022 in hopes to gain more knowledge about drug addiction and relapse, the epigenetics of addiction, and understand how memory plays a role in it as well. After her time at Temple, Madeline intends to enter medical school to become a neurologist. Outside of the lab, Madeline is a part of Phi Sigma Sigma and Diamond Dogs. 

Lilly is a sophomore in the honors program with a major in Neuroscience and minor in clinical and health psychology (class of 2025).
