Research Activities/Interests:
Dr. Dyavar’s research projects are focused on developing effective combination antiretroviral therapies (cART) to limit human immunodeficiency virus (HIV) replication in lymphatic tissues with the goal of clearing HIV reservoirs in infected patients. He has several collaborative projects ranging from identifying novel drug-drug interactions during HIV-TB combination therapies; finding the novel molecular targets to develop novel therapies to treat Parkinson’s disease; pharmacokinetic and pharmacogenomics analysis of rifamycin antibiotics and rifamycin-efavirenz combination therapies to identify the role of drug transporters and drug metabolizing enzymes to develop effective TB and HIV-TB combination therapies.
