Emerman

During his 36-year career at Fred Hutch Cancer Center, Michael Emerman, PhD, an Affiliate Professor in the UW Department of Microbiology, made fundamental discoveries about HIV, the retrovirus that causes AIDS. Over his career, Michael trained 27 graduate students and 16 postdoctoral/medical fellows. He was the MCB graduate program co-director for 8 years, taught graduate virology to countless students since 2005, and organized Thursday morning virus group meeting, which has been active since 1992. Thank you Michael for all you've done for our community. Read more about Michael's legacy here.
