Our Research

The purview of our research is broad, encompassing investigations into the basic principles of molecular, cellular, and organ-level biology and their relationship to disease.  Some current areas of fundamental interest include single molecule structure; protein assembly; molecular and cell biology; cell signaling and motility; membrane trafficking; physiology; systems biology; engineering and technology development. Insights into disease mechanisms derived from basic studies form the basis for translational research into new diagnostic and therapeutic approaches.

DIR investigators also conduct concept-based clinical studies in the areas of interventional and surgical cardiology; pulmonary medicine; sickle cell anemia; bone marrow transplant; and hematologic disorders. The DIR recruits patients from across the U.S. to enroll in innovative clinical trials at no cost to them.

Principal Investigators
