Siddhesh Kamat is currently an Associate Professor, a SwarnaJayanti Fellow, and an EMBO Young Investigator, in the Department of Biology at IISER Pune. Dr. Kamat completed his BTech from the Institute of Chemical Technology (former UDCT) in 2007, and a PhD from the Department of Chemistry at Texas A&M University in 2012. Dr Kamat was the 9th Irving S. Sigal Postdoctoral Fellow of the American Chemical Society at the Department of Chemical Physiology, The Scripps Research Institute. He joined IISER Pune in 2016.


Chemical biology of mammalian lipid signalling pathways

Dr. Siddhesh Kamat's group is interested in studying the biological mechanisms of lipid signaling pathways in the mammalian nervous and immune system. To achieve their goals, the group integrates aspects of chemical biology, biochemistry, molecular and cell biology, immunology, animal and/or cellular models, in conjunction with advanced mass spectrometry (LC-MS) based metabolomics and proteomics techniques. The long term goal is to identify and understand as-of-yet uncharacterized lipid signaling pathways in vivo, annotate enzymes and receptors that regulate their biology and provide new insights and therapeutic paradigms for orphan and/or emerging human neurological and immunological diseases.
