Andrzej Joachimiak is the Director of Structural Biology Center and Midwest Center for Structural Genomics. He is an expert in synchrotron-based X-ray crystallography and structural biology. At Argonne, he has made significant contributions to the high-throughput crystallography using synchrotron radiation and the development of state-of-the-art facilities for macromolecular crystallography. The development and integration of the novel synchrotron beamlines, exploitation of the anomalous signal-based phasing methods in the third-generation environment and integration of hardware and software at the Structural Biology Center beamlines at the Advanced Photon Source contributed very strongly to the enhanced efficiency of such facilities worldwide.
