Trish Gregg

Professor, Principal Investigator

I believe that teamwork and collaboration are incredibly important. Working as a member of a team to solve challenging problems is what makes science fun for me. I’m incredibly fortunate to work with outstanding young scientists who have inspired my science and thinking immeasurably. These amazing students and postdocs are outstanding in scholarship, citizenship, and teamwork. They make my research group what it is, and are why I am so excited to go to campus and do science every day.
