Meet the current members of our lab. We are a diverse group at all career stages with a range of backgrounds and scientific expertise that together build a productive and collaborative lab atmosphere. We also have fun outside of the lab – check out our gallery page for some examples!

Principal Investigator

John Krais, PhD

John trained in Bioengineering at the University of Pittsburgh (undergrad) and the Center for Chemical, Biological, and Materials Engineering at the University of Oklahoma (grad school) where he worked on targeted drug delivery strategies. He then did postdoctoral training at Fox Chase Cancer Center and focused on DNA damage response mechanisms and therapeutics that target those pathways. When not in the lab, John tries to spend as much time outdoors with his wife Tatiana and two Rhodesian Ridgebacks.
