About me

Since July 2018, I have been a quant analyst at BofA in Chicago.

From August 2015 to August 2018, I was a Doob postdoc in the Mathematics Department of the University of Illinois at Urbana-Champaign. I also worked for Wolfram and for the CQF program.

In May 2015, I finished my doctoral thesis at the I-Math of UZH in Zurich, Switzerland. My supervisors were Alberto Cattaneo and Ashkan Nikeghbali and I was partially supported by the Forschungskredit grant K-71104-04-0.

Before joining the I-Math I took Part III of the Mathematical Tripos at the University of Cambridge (my thesis was on quantum rate-distortion theory).

Prior to that, I also completed the highly, highly recommended M.Sc. in Quantum Fields and Fundamental Forces at Imperial College London (this time my thesis was on zeta function regularization).

Previously, I worked in investment banking in London and Zurich (JPMorgan, Nomura and UBS).


My interests are primarily in number theory, theoretical physics and quantitative finance. I like to keep it as orthogonal as possible.
