Laura Banaszynski is an Associate Professor in the Cecil H. and Ida Green Center for Reproductive Biology Sciences. She holds secondary appointments in the Department of Obstetrics and Gynecology and Children's Research Institute.
Dr. Banaszynski received her BS in Chemistry from The University of Notre Dame. She completed her PhD in Chemical & Systems Biology with Tom Wandless at Stanford University. She was then a Damon Runyon postdoctoral fellow with David Allis at The Rockefeller University. In 2015, Dr. Banaszynski joined the faculty of UT Southwestern.
Dr. Banaszynski studies epigenetic contributions to gene expression and genome stability in mammalian systems. Her research focuses on the dynamic regulation of chromatin states at both coding and non-coding regions including the influence of histone variant incorporation on histone post-translational modification states. Her long-term goal is to improve our understanding of the chromatin-based mechanisms regulating fundamental cell-fate decisions in pluripotency and differentiation that are essential to our understanding of developmental processes.
