Brief Profile

Had received PhD degree in Bio-Medical Sciences, from TN Dr. MGR medical University, chennai and obtained post-doctoral training at Institute Pasteur de Lille, France and Columbia University, Manhattan, New York, USA. Employed earlier as Assistant Investigator in Feinstein Institute of Medical Research, New York, USA. His major research interests have been in the field of Molecular Immunology, particularly Innate Immune function across autoimmune and infectious diseases. Studied extensively on the key role played by the renal macrophages/dendritic cells towards activation of renal endothelium in the pathogenesis of lupus nephritis, identified them as an unique marker for disease onset, progression and relapse of Lupus nephritis among varied murine models and human kidneys. His current research focus is to study the molecular analysis of monocyte subsets within patients infected with mycobacterium tuberculosis and to decipher the role of vitamin D and micronutrients as a modulator of immune response in Tuberculosis
