Profile Introduction

My research is in the field of stem cell biology and translational regenerative medicine. Our group is specifically focused on the use of pluripotent stem cells in naturally occurring diseases in companion animals as platforms to conduct high level translational research to facilitate the development of novel regenerative medicine therapeutics for human and veterinary use. Ongoing projects in the lab include the regulatory networks that govern the naive pluripotent state in canine pluripotent stem cells and cellular replacement treatments for canine diabetes mellitus . Our group is always looking for the brightest and most enthusiastic future scientists that are eager to realize the incredible potential and promise of regenerative medicine.

Research Interests
