I am now a postdoctoral research assistant in mathematics at University of Oxford in the group of Professor Francis Brown.
Here, you can find my CV, my thesis and the slides of my defense.
Research Interests:
 Elliptic Analogs of Multiple Zeta Values, Elliptic Motives, Modular Forms, String Amplitudes
