Researcher

Gerald Penn

Gerald Penn is a professor of computer science at the University of Toronto whose research connects grammar engineering, speech summarization and multimodal language models. He earned a Ph.D. from Carnegie Mellon in 2000 and worked at Bell Labs from 1998 to 2001. His research includes the Attribute Logic Engine for typed-feature grammars, constraint handling rules for HPSG, and speech summarization for spontaneous conversation. He co-founded Private AI and served as its chief science officer, and he was a Beckman Senior Fellow in 2006. He teaches computational linguistics at Toronto.

Timeline

  1. 1998–2001

    Bell Labs and Carnegie Mellon

    He earns a Ph.D. from Carnegie Mellon's School of Computer Science in 2000 and works in Bell Labs' Multimedia Communications Research Laboratory from 1998 to 2001.

  2. 2000

    ALE for typed-feature grammars

    In a 2000 preprint, he presents the Attribute Logic Engine as a Prolog preprocessor for typed feature structures and its extension to a grammar development system for HPSG.

  3. 2000

    Applying CHR to HPSG

    In his 2000 preprint 'Applying Constraint Handling Rules to HPSG,' he explains that CHR extends feature-structure constraints with declarative relations and complex antecedents.

  4. 2006

    Beckman Senior Fellowship

    He becomes a Beckman Senior Fellow at the Beckman Institute in 2006.

  5. 2006–2010

    Speech summarization

    In 2006, he coauthors a study comparing textual, acoustic and spoken-language features for spontaneous-conversation summarization. In 2010, he presents a talk summarizing his group's speech-summarization research.

  6. By 2022

    Co-founding Private AI

    By 2022, he is a co-founder and former chief science officer of Private AI.

  7. 2026

    Multimodal gaze estimation

    In 2026, he coauthors “Predicting Gaze Location without Camera or Eye-Tracker,” a paper that uses multimodal LLMs to analyze screen content with mouse location when estimating gaze.

  8. As of October 2026

    Professor at Toronto

    He is a professor of computer science at the University of Toronto. In Fall 2025, he teaches Discrete Mathematical Models of Sentence Structure; in Fall 2026, he teaches Introduction to Computational Linguistics.

  2. The United States employs an estimated 53% of people in our data with a known employment countryOur estimates of where AI careers are concentrated now and how countries’ shares of dated positions changed over time.
  3. 46% of living people in our data with known birth and employment countries work outside their birth countryOur estimate of cross-border careers in AI, from country of birth and the country of each current organization.
  4. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionOur estimates of where the people shaping AI studied and where their careers led, from education records in cited biographies.
