Professional Summary:
Research interests include development of single particle and tomography cryogenic electron microscopy methods for challenging samples. In particular, we are interested in improving three-dimensional structures for low copy number biological structures in isolation and within cells. We are also working to find ways to obtain three-dimensional structures of very small protein molecules in isolation. Also, in collaboration with other researchers at the HWI, we develop methods to increase the success rates of micro-crystal electron diffraction experiments. At the HWI Cryogenic Electron Microscopy Center, we provide high throughput sample screening, data collection and analysis for biological samples from many research groups.
