Professional Interests

Dr. Ke Zhang is trained in physics and biophysics with extensive experience in x-ray experiments on metalloproteins and other systems. He has worked continuously on x-ray absorption spectroscopy. These include numerous XAFS studies of metalloproteins, especially zinc proteases. More recently, he has worked on XAFS instrumentation oriented projects, such as the development of a stop-flow system, the dead time correction of the Ge detector, and polarized XAFS on a single monolayer of protein. Since 1997 he has worked primarily on x-ray detector development. He founded HD Technologies, Inc. in 1997. The primary business of the company is the research and development of various multilayer analyzer array detectors for x-ray fluorescence detection at synchrotron sources.
