Researcher

David Alvarez-Melis

David Alvarez-Melis is a computer scientist whose research connects optimal transport, data-centric machine learning, and interpretable AI. After mathematics degrees at ITAM and NYU, he worked in IBM Research's Speech Recognition Group and earned a computer science PhD at MIT. In 2018, he coauthored a paper on self-explaining neural networks and a 2021 paper on dataset transformation with Wasserstein gradient flows. Harvard SEAS appointed him an assistant professor in 2022, and in 2024 he joined the Kempner Institute as associate faculty. He is an assistant professor of computer science at Harvard SEAS, where he leads the Data-Centric Machine Learning group; he also works as a researcher at Microsoft Research New England.

Timeline

  1. 2006–2013

    Mathematics degrees at ITAM and NYU

    From 2006 to 2011, he studies applied mathematics at ITAM and earns a BSc. At Courant Institute, NYU, he completes an MS in mathematics in 2013.

  2. 2013–2014

    Speech recognition at IBM

    From 2013 to 2014, he works at IBM Research as a Supplemental Researcher in the Speech Recognition Group.

  3. 2014–2019

    A PhD on optimal transport

    At MIT CSAIL, he completes a PhD in computer science in 2019 under advisor Tommi Jaakkola. His thesis extends optimal transport to model structured data and invariances, with NLP applications including unsupervised word translation, sentence similarity, domain adaptation, and WordNet matching.

  4. 2018

    Self-explaining neural networks

    In 2018, he coauthors Towards Robust Interpretability with Self-Explaining Neural Networks at NeurIPS. The paper puts explanation into the learning process and sets three goals for explanations: explicitness, faithfulness, and stability.

  5. 2019–2021

    A postdoc at Microsoft Research

    In 2019, he joins Microsoft Research New England as a postdoctoral researcher.

  6. Since 2021

    Senior researcher at Microsoft

    He becomes a Senior Researcher at Microsoft Research New England in 2021, in its Machine Learning and Statistics group. His data-centric approach aligns and compares datasets.

  7. 2021

    Dataset transformation through optimal transport

    With Nicolò Fusi, he publishes Dataset Dynamics via Gradient Flows in Probability Space in 2021. The paper models dataset transformation with Wasserstein gradient flows and tests the method on classification constraints and transfer learning.

  8. 2022

    Joining Harvard SEAS

    In 2022, he joins Harvard SEAS as Assistant Professor of Computer Science and Applied Mathematics from Microsoft Research New England, where he is a Senior Researcher in the Machine Learning and Statistics group.

  9. July 2024

    Associate faculty at Kempner

    In July 2024, he joins the Kempner Institute as an associate faculty member while serving as a Harvard assistant professor of computer science. His research addresses learning in constrained, dynamic, and complex environments.

  10. Since 2023

    Assistant professor at Harvard

    In 2026, he is an assistant professor of computer science at Harvard SEAS and leads the Data-Centric Machine Learning group. He also works as a researcher at Microsoft Research New England.
