Dr. Mehta's research and clinical paths have focused on treatment of and protection against infections in immunocompromised hosts, including patients with organ transplants, limb transplants, stem cell transplants, leukemia/lymphoma, cystic fibrosis, and HIV/AIDS.
Dr. Mehta's research area is broadly within clinical and translational Transplant Infectious Diseases, with a primary research aim to develop predictive immunologic and virologic signatures of risk for viral diseases in patients receiving immunosuppressive agents. He primarily employs polychromatic flow cytometry to phenotypically and functionally describe subsets of the protective immune system.
He is currently the co-investigator and primary clinical investigator on the Protective Immunity Project (PIP), a collaborative research projected between the Emory Transplant Center (Christian Larsen, MD, DPhil), the Emory Vaccine Center (Rafi Ahmed, PhD) and the NIH. Dr. Mehta also serves as a co-investigator and clinical investigator of Project 4 (Rafi Ahmed) of the Emory University Influenza Pathogenesis & Immunology Research Center (IPIRC), is one of five national Influenza Centers of Excellence funded by NIH/NIAID. In this project, the group hopes to discern the differences in immunologic memory elicited by different influenza vaccines. Dr. Mehta also serves at the co-investigator and PI of the Viralogic Monitoring Cores of Emory's Clinical Trials in Organ Transplantation (CTOT) and Clinical Trials in Organ Transplantation in Clinical (CTOT-C) trials, including CTOT-C02, CTOT-10, CTOT-15, and CTOT-16. Recently, Dr. Mehta has replaced Dr, Allan Kirk as the PI of the Emory Transplant Center's Immune Monitoring and Assay Development in Organ Transplant Recipients (IMP) and as the Directory of Emory Transplant Biorepository.
Dr. Mehta attends on the Emory University Hospital Transplant Infectious Diseases, Emory University Hospital General Infectious Diseases, and the Emory University Orthopedic and Spine Hospital Infectious Diseases consultation services.
As Assistant Director of the Transplant Infectious Diseases, Dr. Mehta aids G. Marshall Lyon III, Director of Transplant Infectious Diseases, in developing programatic improvements in care of transplant recipients at the Emory Transplant Center and Emory University Hospital.
Dr. Mehta also serves as the Consultant for Occupational Exposure at Emory University's Yerkes National Primate Center. In this role, he supervises the care of employees at Yerkes who have incurred a work related exposure or injury, including Herpes-B exposures.
