### About me

I went to Reed College where I got a BA in Mathematics, and wrote a research thesis with David Perkinson. I am from Bucharest, Romania.

### Research

0. Belief propagation analysis for random hypergraph colorings, 2016, in preparation.

1. Florescu, L., Peres, Y. Optimal control for diffusions on graphs, 2015, in preparation. Abstract

Starting from a mass $\delta_0$ on a graph, we investigate the minimum number of steps needed to transport a constant mass $p$ outside of the ball of radius $n$. The steps of our ``\emph{controlled diffusion}" process are as follows: at each time, we select any site with positive mass and topple its mass equally to its neighbors.
