I have moved to Columbia University, where I am an Assistant Professor in the Statistics Department. Before, I was a DPhil student in the Mathematical and Computational Finance Group. My research is focused on the robust approach to Mathematical Finance, which does not start with an a priori model but rather with the information available in the markets. My project was supervised by Prof. Jan Obloj.
