Geoffrey Chang is a professor at the University of California, San Diego's Skaggs School of Pharmacy and Pharmaceutical Sciences and Department of Pharmacology, School of Medicine. His laboratory focuses on the structural biology of integral membrane proteins, particularly exploring X-ray crystallography techniques for solving the tertiary structures of membrane proteins that are notoriously resistant to crystallization. The laboratory has specialized in structures of multidrug resistance transporter proteins in bacteria. In 2001, while a faculty member of The Scripps Research Institute, Chang was awarded a Beckman Young Investigators Award, designed to support researchers early in their academic careers, for his work on the structural biology of multidrug resistance. Chang announced a move from Scripps to neighboring UC San Diego in 2012.
