This coming Fall, I will start a postdoc at Caltech hosted by Venkat Chandrasekaran and Joel Tropp.

I obtained my PhD in Applied Mathematics from Cornell University, where I was advised by Damek Davis. Before going to Cornell I completed my MSc in Mathematics and two BS in Mathematics and Systems and Computing Engineering at Los Andes University. There I was co-advised by Mauricio Junca and Mauricio Velasco.

I spent the Fall of 2020 interning with the Algorithms and Optimization team at Google Research, where I was hosted by Miles Lubin and David Applegate.

Broadly speaking, I am interested in the beautiful interplay between continuous optimization, geometry, and statistics and its applications to data science, machine learning and signal processing. In case you would like to take a look, here is my CV.


2021-06-17 Damek Davis, Dmitriy Drusvyatskiy, and I just uploaded a new paper called Escaping strict saddle points of the Moreau envelope in nonsmooth optimization.

2021-06-09 New paper entitled Practical Large-Scale Linear Programming using Primal-Dual Hybrid Gradient in collaboration with David Applegate, Oliver Hinder, Haihao Lu, Miles Lubin, Brendan O'Donoghue, and Warren Schudy.

2021-05-17 Ben Grimmer and I just uploaded a new paper entitled Optimal Convergence Rates for the Proximal Bundle Method.

2021-02-09 David Applegate, Haihao Lu, Miles Lubin, and I just uploaded a new paper entitled Infeasibility detection with primal-dual hybrid gradient for large-scale linear programming.
