Associate Professor
Gareth Roberts is an Associate Professor in the Department of Linguistics at the University of Pennsylvania, where he serves as Graduate Chair. He is also a faculty member of the Psychology Graduate Group, founder and director of the Cultural Evolution of Language Lab, and co-director of the Social and Cultural Evolution Working Group at Penn. Roberts earned his PhD in Linguistics from the University of Edinburgh in 2010, following an MSc in Evolution of Language and Cognition (2006) and a BA in German and Russian (2003) from the University of Nottingham. His academic journey includes postdoctoral positions at Yeshiva University and the University of Stirling before joining Penn as an Assistant Professor in 2014, where he was promoted to Associate Professor in 2022. His research focuses on the role of social and communicative pressures in shaping language emergence and evolution. Roberts investigates fundamental questions about linguistic variant spread, phonological system structuring, and how communication shapes linguistic structure. His work bridges linguistics, cognitive science, and cultural evolution through innovative experimental approaches using artificial languages and laboratory simulations. Analysis of Roberts' recent publications reveals a consistent focus on experimental semiotics, with particular attention to social biases in language evolution, phonological organization, indexicality emergence, and the dynamics of linguistic variation. His work often combines computational modeling with human experiments to isolate specific mechanisms driving language change. Linguistic Society of America Cognitive Science Society Philological Society Cultural Evolution Society Roberts has successfully secured substantial research funding including an NSF PAC Grant ($102,648), Penn URF Research Grants ($12,155), MindCORE initiative grant ($600,000), and multiple smaller grants totaling over $20,000. His lab currently includes researchers investigating diverse topics from case and gender marking emergence to AI agent effects on group dynamics, linguistic and genetic data in British history, and phonological space organization. The Cultural Evolution of Language Lab, which Roberts founded and directs, conducts cutting-edge research using experimental semiotics methodologies. Current projects examine how social factors influence language change, the emergence of linguistic structure through communication, and the interaction between iconicity and combinatoriality in communication systems.
