About Me
Welcome to my page! My name is Igor Halperin, and I am currently a Vice President in Quantitative Research at JP Morgan. My interests include multi-name credit derivatives models, calibration and inverse problems, and cutting-edge computational methods  in option pricing theory, mostly but not exclusively in the context of credit derivatives models. This site is currently under construction. For the time being, it contains only some of my working papers and presentations on quantitative finance.
