Postdoctoral Biochemist in condensate biology

Website leunglab Johns Hopkins University/Leung Lab

We are looking for a postdoctoral fellow to join the Leung Lab at the Johns Hopkins University. We will dissect the biochemistry of biomolecular condensate regulation by poly(ADP-ribose).

Poly(ADP-ribose) is an RNA-like polymer and therapeutically important protein modification as evidenced by the FDA approval of poly(ADP-ribose) polymerase inhibitor for treating cancers. Here, we will investigate the condensate biology, specifically RNA-enriched granules, in viral infection and/or neurodegeneration. Our ultimate goal is to translate basic scientific discovery to biomarkers or therapeutic targets.

Over the years, our team has developed novel techniques to investigate poly(ADP-ribose) and discovered its roles in controlling condensate formation, disassembly, and composition. Therefore, these insights provide us a unique edge in exploring the science and developing the candidate’s own research program for their future independent career.

The ideal candidate should have prior experiences in protein or nucleic acid biochemistry. Experiences with post-translational modifications, structural biology, proteomics, biophysics, single-molecule studies, or relevant disease biology are a plus.
