Ranjit Kumar

I am working as a quantitative researcher in Deutsche Bank in IMM team. My role is to validate the CCR models in internal model management team. Before that I had worked in JP Morgan & Chase in Equity Reserch Team. I was an Assistant Professor in Physics. I have taught several Physics courses at the Dyal Singh College, for the seven and half years. I was also a research scholar at the Department of Physics and Astrophysics, University of Delhi. I did my schooling from my native place Sitamarhi, in Bihar.
