My lab's research focus is structure function characterization of macromolecules involved in the pathogenesis of diseases in organisms ranging from humans to plants and bacteria. This includes unravelling the molecular mechanisms of host-pathogen interactions, epigenetic regulations in host system under stress conditions etc. To achieve these interests, we are using different combinations of biochemical, biophysical and computational methods in our laboratory. Our lab is well funded by CSIR, DBT and DST grants, FRPDF (WB Govt).
Our lab is always looking for enthusiastic students (preferably qualified DBT/ICMR/UGC/CSIR NET-JRF) who have done their MSc in lifesciences/Biochemistry/Chemistry/Botany. If you are interested in this exciting research, you can contact me @ sdey.dbs@presiuniv.ac.in
