Joseph Brzostowski, Ph.D.

Chief, Twinbrook Imaging Facility, Rockville
Senior Associate Scientist, Laboratory of Immunogenetics


Dr. Brzostowski received his B.A. from Rutgers College in 1990 and his Ph.D. in 1998 from the University of Virginia. As a postdoctoral fellow at the National Institute of Diabetes, Digestive and Kidney Diseases, he used live cell imaging technologies to study the mechanisms that regulate directional cell movement in the model organism Dictyostelium discoideum. Dr. Brzostowski was recruited to LIG in 2005 to establish a core imaging facility that would provide principal investigators, fellows, and students the ability to carry out sophisticated live cell imaging experiments with cutting-edge technologies. Dr. Brzostowski is foremost a teacher, training those who use his facility the fundamentals of microscopy to eventually become masters themselves in modern imaging modalities. In addition to his duties at LIG, Dr. Brzostowski is a faculty member of the summer Physiology Course at the Marine Biological Laboratory at Woods Hole, Massachusetts, he has taught a variety of international microscopy courses and teaches locally at the FAES.
