Nov. 28, 2011—Jennifer Plank, a current student in Cell and Developmental Biology, received the award in the graduate student category. Working with Patricia Labosky, Ph.D., Jennifer studies regulators of pancreatic beta cell mass expansion. She has identified important roles for the neural crest and for the transcription factor Foxd3 in the beta cell. The findings from both...
