Daniel Dempsey, PhD
Assistant Professor, Dermatology
Biography
The mission of Prof. Dempsey’s lab is to understand the basic biological mechanisms of proteins that are essential to human health and disease. The lab focuses on investigating the structure, function, and regulation of proteins involved in cell signaling, epigenetics, and gene regulation. Prof. Dempsey and his team use chemical, semi-synthetic, biophysical, and cellular approaches to elucidate mechanisms for how post-translational modifications regulate protein function. They are also interested in advancing new chemical strategies to investigate PTMs and protein function.
Prof. Dempsey’s current focus is on understanding the function and regulation of deubiquitinases and RNA-modifying proteins, which are emerging as attractive therapeutic targets in several cancers. Their work will shed light on the mechanistic consequence of PTMs, and how dysregulation of these proteins may lead to disease. The team’s goal is that these findings will pave the way for the rational design of new therapies for the treatment of cancer.
