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.
Charlotte graduated from Colgate University in 2013 with a degree in neuroscience and biology. Following graduation, she worked as a research technician at McLean Hospital studying the role of muscarinic receptor subtypes in rodent models of cocaine addiction. She then decided to pursue her PhD at Weill Cornell Medicine, where she joined the lab of Dr. Anjali Rajadhyaksha. Her thesis research examined the role of a neuropsychiatric risk gene, cacan1c, in rodent models of relapse behavior, focusing on the neural circuits underlying behavioral phenotypes. In the Wimmer lab, Charlotte is excited to explore the epigenetic and transcriptional changes underlying persistent opioid craving and relapse.
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.
Caesar Imperio, MD, PhD.
Psychiatry Resident and Postdoctoral Fellow
Caesar graduated from The University of Scranton in 2009 with a B.S. in Neuroscience. Upon completion of his undergraduate studies, he then pursued a Ph.D. in Neuroscience at the Penn State College of Medicine under the mentorship of Drs. Sue Grigson and Bill Freeman. His graduate work focused on developing an animal model that behaviorally stratified animals on their addiction-like behavior based on their avoidance of a natural reward. Furthermore, he also examined the interplay between environmental enrichment and heroin self-administration at the behavioral, genetic, and epigenetic levels. After obtaining his Ph.D. in 2015, Caesar decided he wanted to do more with his knowledge of the basic sciences and integrate it into clinical practice. Therefore, Caesar then enrolled at the Rutgers Robert Wood Johnson Medical School and obtained his M.D. in 2019. Caesar is currently a psychiatry resident on the research track at Temple University. In the Wimmer laboratory, Caesar plans to investigate the molecular changes associated with extended drug abstinence that may influence craving and relapse.
Hannah Mayberry is a first-year graduate student in the Brain and Cognitive Sciences doctoral program. Prior to joining Dr. Wimmer's lab, Hannah earned her B.S. in Biology from Virginia Commonwealth University. During her undergraduate studies, Hannah also interned at the Virginia Institute for Psychiatric and Behavioral Genetics. Following graduation, Hannah worked for two years as a full-time Research Assistant at the Clinical Behavioral Pharmacology Lab. These experiences introduced Hannah to the biopsychosocial factors contributing to substance abuse and anxiety disorders; both of which are research themes she hopes to expand upon in graduate school. Hannah is specifically interested in examining the neural and epigenetic mechanisms contributing to maintenance of drug addiction and propensity for relapse.
Andre graduated with a Master’s degree in Psychology, with a concentration in Biopsychology, from Hunter College at the City University of New York. While at Hunter College, he was a research fellow studying the neural mechanisms of addiction. For his Master thesis, he investigated methamphetamine-induced conditioned place preference in adolescent male and female mice of two strains, C57Bl/6 and 129/SvEv. After graduating from Hunter College, he joined Dr. Wimmer’s lab as a PhD student in Temple’s Brain and Cognitive Sciences program. Under Dr. Wimmer’s guidance, Andre plans to investigate the transgenerational epigenetics of drug addiction. In his free time, he enjoys listening to music, visiting the Caribbean and reading.
Lab Manager and Research Technician
Angela Bongiovanni graduated from Temple University in December of 2017 with a B.S. in Neuroscience and a B.A. in Psychology. She joined the Wimmer lab in 2016 as an undergraduate researcher, and post-graduation, moved on to become the laboratory manager in January of 2018. Her primary project in the lab focuses on the effects of the female estrous cycle on drug-taking in a transgenerational model of opioid addiction. Her past projects have included analyzing the effects of a novel pharmaceutical, NS2359, on opioid reinstatement and rewarding efficacy; profiling spatial memory deficits produced by opioid use; and investigating the effects of early life adversity on drug-taking. She is also looking forward to providing data for a collaborative project focused on the effects of aging on drug-taking. Dedicated to science education, Angela has also spent time teaching chemistry at Temple. Her long-term plans are to enroll in a PhD program in Neuroscience.
