About

I'm an Assistant Professor of Computer Science at Harvard SEAS where I lead the Data-Centric Machine Learning (DCML) group. I'm also an Associate Faculty at the Kempner Institute, and have affiliations with the Center for Research on Computation and Society and the Harvard Data Science Initiative. I am also a researcher at Microsoft Research New England.

My research seeks to make machine learning more broadly applicable (especially to data-poor applications) and trustworthy (e.g., robust and interpretable). I am particularly interested in the implications of these two directions for applications in the natural and medical sciences. My approach to the first of these goals draws on ideas from statistics, optimization, and applied mathematics, especially optimal transport, which I have used to develop methods to mitigate data scarcity by various types of geometric dataset manipulations: alignment, comparison, generation, and transformation. This talk provides a high-level overview of this part of my work. As for trustworthy machine learning, I have worked on methods for explaining predictions of black box models, showed their lack of robustness, proposed methods to robustify them, and sought inspiration in the social sciences to make them human-centered. In the past, I worked on various aspects of learning with highly-structured data such as text or graphs, ranging from learning representations of structured objects, to generating them, to interpreting models that operate on them.

Prospective lab members: If you are interested in joining my group at Harvard, please read this.

Bio

I obtained a PhD in computer science from MIT, where I worked at CSAIL on various topics in machine learning and natural language processing. I also hold BSc (Licenciatura) and MS degrees in mathematics from ITAM and Courant Institute (NYU), respectively. During the latter, I worked on semidefinite programming for domain adaptation under the supervision of Mehryar Mohri. Between Master's and PhD, I spent a year at IBM's T.J. Watson Research Center, working with Ken Church and others in the Speech Recognition Group.

Current and past courses I have taught or TA'd:

Teaching Philosophy
Explaining is understanding.

The following extract is from David Goldstein's book on Feynman:

"Feynman was a truly great teacher. He prided himself on being able to devise ways to explain even the most profound ideas to beginning students. Once, I said to him, "Dick, explain to me, so that I can understand it, why spin one-half particles obey Fermi-Dirac statistics." Sizing up his audience perfectly, Feynman said, "I'll prepare a freshman lecture on it." But he came back a few days later to say, "I couldn't do it. I couldn't reduce it to the freshman level. That means we don't really understand it."

Prospective Students/Postdocs/Interns

I am always looking for motivated students and postdocs to join my group. Unfortunately, I am not able to respond to all emails. So, depending on your situation, please follow one of the follwing routes:

  • You are a prospective PhD student: please apply directly to our PhD program and list me as a faculty of interest. Applying to CS or Applied Math are both fine. Admissions are centralized and made by committee.
  • You are a student already at Harvard: send me an email with the subject line "[Prospect] Interested in joining your group (Harvard Student)" and a brief description of your interests and background.
  • You are a student interested in an internship or visiting position : send me an email with the subject line "[Prospect] Interested in joining your group (External Student)" and a brief description of your interests and background. Update: I am not currently taking new visiting students for Fall 2024. Please check back later!
  • You are a prospective Postdoc: send me an email with the subject line "[Prospect] Interested in joining your group (Postdoc)" with a CV, link to your publications, and a brief description of your interests and background.
In any of the situations above, please include the word "Monge" anywhere in your the main body of your email, to show me you've read this page and are not just sending a generic email to all faculty (I learnt this trick from Finale).

If your email is not formatted as above, my filters won't catch it so I will almost certainly not see it.

Misc

Outside of research, I enjoy running, brewing beer and playing guitar. I also like quotes. Here's a few more:

"We cannot solve our problems with the same thinking we used when we created them." - A. Einstein
"The real danger is not that computers will begin to think like men, but that men will begin to think like computers" - Syndey J. Harris
