Leonardo Cotta

Postdoc Fellow

💬 About

I’m a postdoc fellow at Vector Institute, where I’m hosted by Chris J. Maddison. I received my PhD degree in computer science at Purdue University, where I was advised by Bruno Ribeiro. Before that —in a distant and happy land— I was a BSc student (also in CS) at UFMG, Brazil. During my time as an undergrad I worked with distributed algorithms (at UFMG) and quantum computing theory (at University of Calgary).

📝 Research

I develop machine learning and causal inference methods for high-stakes applications of AI, such as science and recommendation engines. My long-term goal is to deliver new AI solutions that have real, tangible world impact. It’s going to be bitter, but now is our time to build. To this end, my work contributes algorithms and models that can leverage diverse, complex data to discover, evaluate, deliver, and monitor system interventions.
