Meet our lab members! 

We are a small group of experts dedicated to facilitating excellent data collection and to improving Cryo-EM methods. We are primarily focused on running the Cryo-EM Core Facility at UMass Chan Medical School, but we do also conduct research on the optimization of Cryo-EM that we share with the community through occasional publication.
