Research and Clinical Interests

My research interests include: (1) understanding the interaction of bacterial LPS and LOS with the innate and adaptive immune system towards development of adjuvants, immunomodulatory agents, antibiotics, and vaccines; (2) manipulating innate immune reactions in treatment of neurotrauma and stroke; (3) therapeutic and diagnostic applications of human Sertoli and other testicular cells; (4) targeting galectin-3 and other galectins for treatment of cancer and organ fibrosis.
