Timeline

  1. 1998–2007

    Engineering degrees in Uruguay and Minnesota

    He earns a BSc in electrical engineering from the Universidad de la Republica in Uruguay in 1998. In 2005 and 2007, he earns MSc and PhD degrees in electrical and computer engineering from the University of Minnesota.

  2. 2008

    Joining Penn

    He joins the University of Pennsylvania in 2008.

  3. 2010

    An NSF CAREER Award

    In 2010, he receives an NSF CAREER Award as an assistant professor of electrical and systems engineering at Penn.

  4. 2019

    Random-edge neural network

    With Mark Eisen, he introduces the random edge graph neural network (REGNN) for wireless resource allocation. Its graph convolutions use random graphs formed by fading interference patterns.

  5. 2020

    Stochastic graph neural networks

    With Zhan Gao and Elvin Isufi, he coauthors the stochastic graph neural network (SGNN), which modifies distributed graph convolution to account for network changes.

  6. 2022–2024

    IEEE Signal Processing Society awards

    Papers he coauthors receive IEEE Signal Processing Society Best Paper Awards for 2022 and 2024.

  7. 2026

    An IEEE Fellowship and Penn award

    In 2026, he becomes an IEEE Fellow and receives Penn’s S. Reid Warren, Jr. Award.

  8. As of October 2026

    Professor at Penn

    He is the Solomon and Sylvia G. Charp Professor of Electrical and Systems Engineering at the University of Pennsylvania.

From the biography and OpenAlex affiliations (the years of papers that list the organization), so some years are approximate.

  1. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other universityIncludes Alejandro Ribeiro. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other university. We compare doctorate and 5+ year employment links, career timing and current workplaces for 187 major-prize and 1,111 best-paper winners.
  2. People shaping AI work at a median of 3 organizations over a career: 3 for university starters and institute and lab starters, versus 2 for company startersIncludes University of Pennsylvania. Across 6,853 people shaping AI with a dated work role, we estimate a median of 3 parent organizations over a career (mean 3.6), comparing role groups, starting sectors and starting decades from the 1950s to 2020–2026.
  3. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes University of Pennsylvania. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
  4. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes University of Pennsylvania. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
