I am a Postdoctoral Researcher at Universidad de Los Andes. Before, I was a Visiting Assistant Professor at the University of California, Santa Barbara under David R. Morrison. I graduated from the University of Utah in May 2015 with a PhD in Mathematics. I wrote my dissertation in Algebraic Geometry under the supervision of Aaron Bertram.

Research

I am interested in the study of moduli spaces of sheaves, in particular their birational geometry. This goes hand in hand with the study of derived categories of coherent sheaves and Bridgeland stability conditions.
