I am an Assistant Research Professor at the Center for Data Science for Enterprise and Society (CDSES), Cornell University.

Before joining Cornell, I was a postdoc at the CERC in Data Science, Polytechnique Montréal under supervision of Andrea Lodi and Margarida Carvalho. I obtained my Ph.D. in Operations Research under supervision of Mohit Singh, Sebastian Pokutta and Alejandro Toriello at the H. Milton Stewart School of Industrial and Systems Engineering, Georgia Tech. In 2013, I obtained my Mathematical Engineering degree (B.Eng. and M.S. in Applied Math equivalent) under supervision of Roberto Cominetti at the Mathematical Engineering Department, Universidad de Chile.

Research Interests

My main research interests lie at the intersection of optimization and operations research, with a focus on matching markets, resource allocation and subset selection problems. In particular, I develop algorithmic tools and design optimization models to tackle challenges that appear in applications such as online advertising, student-school allocation, online matching platforms, facility location and data summarization. I am also interested in (1) societal challenges that arise in multi-agent and societal systems such as fairness, diversity, and the spread of misinformation; (2) the interactions between optimization and machine learning such as the design of new approaches for submodular optimization.
