Principal Investigator

Jake went to Swarthmore College for his B.A. in Biology and History, and then studied with Pat Zambryski (UC Berkeley) for his Ph.D. in Plant Biology.  After a short stint as a post-doc in Sarah Hake's lab investigating maize development (USDA ARS: PGEC), Jake started his independent group investigating TOR signaling in plants with the NIH Early Independence Award.

September 2019

We got together with the Hake Lab to wish Annis Richardson well as she heads off to start her own group at the University of Edinburgh.  Congrats, Annis!
