RESEARCH SUMMARY

I was trained in physics and high resolution electron microscopy (EM) and moved to cryo-electron microscopy (cryo-EM) in 1992. Since then, I have worked on almost every application of cryo-EM in structural biology, from single particles to 3D protein crystals. My work has focused on improving specimen preparation for single particles and protein crystals and on pushing the resolution limit of data collection using cryo-transmission electron microscopy (cryo-TEM) and focused ion beam/scanning electron microscopy (FIB/SEM).  I have also developed new data collection methods and software for electron crystallography.

My research interests include developing new methods and software to push the resolution limit for single particles and protein crystals, and cryo-electron tomography (cryo-ET).     

Areas of Expertise

1) optimizing the electron optics and parameters of cryo-EM to collect atomic resolution data, 2) improving specimen quality for the TEM grids of single particle and protein crystals, 3) electron crystallography - MicroED, 4) understanding the principles and structures of cryo-TEM, FIB/SEM, 5) automation of data collection
