Arlei Silva

I'm an Assistant Professor of Computer Science at Rice University.

My research focuses on developing algorithms and models for mining and learning from complex datasets, broadly defined as data science, especially for data represented as graphs/networks.

I'm particularly interested in problems motivated by computational social science, infrastructure, and healthcare. The tools that I apply to address these problems include machine learning, network science, graph theory, linear algebra, optimization, and statistics.

I got a Ph.D in Computer Science from the University of California, Santa Barbara, advised by Ambuj Singh, where I was also a postdoctoral scholar. Before that, I got a B.Sc and M.Sc degrees in Computer Science from Universidade Federal de Minas Gerais, in Brazil, advised by Wagner Meira Jr. I've also been a visiting scholar at the Rensselaer Polytechnic Institute, hosted by Mohammed J. Zaki.

My name is pronounced approximately as ARE-LAY.
Pronouns: he/him/his.
