Postdoctoral Fellow, Garfinkel Lab

Sean Beckwith (he/him/his) is a postdoc with David Garfinkel interested in the biology of mobile genetic elements and mechanisms utilized in natural systems to control the movement of these elements. He received his Ph.D. from Stanford University in 2018 and his B.A. from Carleton College in 2012. His doctoral work with Ashby Morrison focused on the interplay between epigenetics and metabolic signaling. He currently investigates the virus-like Ty1 retrotransposon in the budding yeast Saccharomyces supported by an NIH F32 postdoctoral fellowship.


Ph.D., Stanford University, 2018

B.A., Carleton College, 2012
