Open Positions

We are interested in hiring motivated and highly talented post-doctoral and post-baccalaureate fellows, particularly those with expertise in protein or nucleic acid biochemistry, mammalian cell culture, genomics and other high-throughput methods, or single-molecule microscopy.

Consistent with the NIH Unite Initiative, we strongly value diversity in hiring and strive for a welcoming and inclusive culture in the workplace.

Postdoctoral Fellow IRTA

B.Pharm - Hacettepe University, Turkey
Ph.D. - University of Illinois at Chicago

During her PhD studies, Sezen worked on non-canonical translation regulation events and their cellular consequences in bacteria. Her current focus is understanding the molecular mechanisms of eukaryotic ribosome rescue and recycling.

Kelsey Bettridge.
Kelsey Bettridge
Special Volunteer

B.A. - Lawrence University
Ph.D. - Johns Hopkins University

During her PhD studies, Kelsey used single molecule tracking to understand how RNA polymerase finds promoter sequences in bacteria. Kelsey is currently studying the dynamics of translational readthrough and reinitiation in live human cells using advanced imaging techniques.
