My research expertise is in using structural and biophysical methods to probe biomolecular structure, function, and dynamics. Determining atomic-level architecture of biomolecules provides us with striking three-dimensional structural representations of biological machines with exquisite detail. High resolution, undamaged structure-level information is critical to understanding the roles these molecules play in disease processes and in biological mechanisms. In the Bowman Group, our research focus is two-fold.
First, we are developing new methods to crystallize biomolecules, as well as to detect and handle micro- and nanocrystals, for cutting-edge structural techniques, with an ultimate goal to probe how conformational changes mediate function. The techniques we use include electron diffraction methods using cryogenic electron microscopy (Cryo-EM) and X-ray diffraction methods using synchrotrons and X-ray Free Electron Lasers (XFELs).
Second, we are investigating metalloprotein structure, function, and dynamics, using structural and spectroscopic approaches to examine the ways metals impact and modulate function of these proteins. We are working to develop spectroscopic methods for single crystals (electron paramagnetic resonance, UV-visible microspectrophotometry, and energy dispersive X-ray spectroscopy for elemental analysis) to be used in parallel with crystallography.
Our long-term research aims will couple these two areas: using these new structural approaches to interrogate dynamics and conformational changes in metalloproteins.
In addition to the research my group is engaged in, I am also the Director of the National Crystallization Center, a major resource for the structural biology community worldwide (www.getacrystal.org).
