I am a PhD graduate from the Courant Institute co-advised by Charles Newman and Daniel Stein. I am interested in probability theory, statistics, mathematical physics and neuroscience.

During my PhD, I worked on statistical mechanics of point processes, computational neuroscience, stochastic processes and co-developed a neural learning algorithm. My work on point processes for physical systems, focuses on showing long-range orientation order of such processes, that relates to giving mathematical rigorous proof of crystallization in solids. I also co-developed a neural learning algorithm that modifies the well known TD-lambda algorithm from reinforcement learning to suit the biological constraints of neuroscience.

I am currently a quantitative Python developer, and senior analyst at Citibank. I have advanced coding experience in Python and C. I have management experience, I led a wonderful team at a Hungarian company in 2019.
