About me

I am Assistant Research Professor at University of Connecticut . My mentor is Fabrice Baudoin. Before Connecticut, I was a postdoctoral researcher at Instituto de Ciencias Matematicas, Madrid where I worked with José María Martell. I received my PhD from Université Paris-Sud and The Australian National University in 2014, under the supervision of Pascal Auscher and Thierry Coulhon.
