January 2020
Both Nick and Janelle leave the lab to start their careers! Congrats to these two stellar scientists! 

Janelle’s paper is accepted at JBC! 

November 2019
A new preprint from the lab is live here.

We describe the structure of small terminase protein a thermophilic phage, which shows that the helix-turn-helix domains have a fixed geometry. This has major implications for TerL- and DNA-binding. Congrats to all, especially first author Janelle!

We will be using the state-of-the-art high-resolution cryoEM facility at UMMS to determine structures of these complexes. Work on these projects has already begun and we are looking to hire additional help for each project. Any interested Postdoc should send a letter of interest and a CV to Dr Kelch directly at
