Jonathan Pruneda earned his Ph.D. in Biochemistry from the University of Washington for his thesis work with Dr. Rachel Klevit on the enzymatic transfer of ubiquitin by RING-type E3 ligases. For his postdoctoral work, he joined the laboratory of Dr. David Komander at the MRC Laboratory of Molecular Biology on an EMBO Long-Term Postdoctoral Fellowship, where he studied how pathogenic bacteria manipulate host ubiquitin signaling through secreted deubiquitinases. He is currently an Associate Professor in the Department of Molecular Microbiology & Immunology at Oregon Health & Science University, where his group studies ubiquitin signaling through the lens of pathogenic bacteria.
