Sami Yousif

MindCORE Post Doc

Sami received his PhD in Psychology from Yale University. His primary research interest is spatial cognition -- how we perceive, interact with, and represent the spatial world around us. But in his free time, he works on a broad range of topics across cognitive science, including how people evaluate social testimony, how people think about the purposes and mechanisms of things, whether people are 'intuitively theistic', how people represent events, how they represent agency in language, and more. Chances are that if you are interested in any aspect of cognitive science, you'll have some overlapping interest with Sami!

Martin Ho Kwan Ip

LDC Researcher

 ILST Initiative

Martin received his PhD in Psychology at the MARCS Institute, Western Sydney University. He is interested in understanding how speech processing can be shaped by both language-universal mechanisms and our experience with our native language. At the Language and Cognition Lab, Martin's research examines different aspects of speech (e.g., foreign accents, prosody) and their social implications from both a cross-linguistic and a developmental perspective.

Sarah Lee

Post Doc

Sarah received her PhD in Linguistics from the University of Southern California. She uses various experimental methods to examine event representations in language and the mind. How are events represented in the mind? How do mental representations of events relate to linguistic representations of events? Currently, she is specifically interested in the internal temporal structure/complexity of events. She also has broader interests that revolve around meaning and its interfaces - specific topics include evidentiality, subjectivity, comparison classes, and more!

Tyler Knowlton

MindCORE Post Doc

Tyler earned his PhD in Linguistics from the University of Maryland and his BA in Cognitive Science from Johns Hopkins. His research focuses on the meanings of logical expressions like “every” and “most” and asks: What do their mental representations look like? How do the formal details of those representations affect non-linguistic cognitive systems? And what leads children to connect those particular representations with the relevant pronunciations?

Andrea Beltrama

MindCORE Post Doc

Andrea earned his PhD in Linguistics from the University of Chicago and held postdoctoral positions at the University of Konstanz and at the Université of Paris 7. His work investigates how the semantic, pragmatic and social dimensions of meaning contribute to determining the content conveyed by linguistic utterances in communication. He pursues this goal through the lens of various linguistic phenomena, including intensification, descriptive (im)precision, subjectivity, discourse markers and alternative-based reasoning. 

Madison Paron

Lab Manager

Madison earned her B.A. in Cognitive Sciences from the University of Pennsylvania in 2019. She is interested in neurolingistics, specifically evaluating the processes underlying the acquisition of verbal and signed languages. Outside of research, Madison enjoys skiing and spending time with her family.


Ugurcan Vurgun

5th Year


Following some time in the industry, Ugurcan received his Master's degree in Linguistics from Bogazici University in Turkey, where he studied the syntax of focus particles in Turkish. He is now a Ph.D. candidate in Linguistics at the University of Pennsylvania. He is interested in event cognition. Outside of research, he enjoys reading about astronomy and spending time with his kids. 

June Choe

4th Year


June is interested in psycholinguistics and the mechanisms of ambiguity resolution in particular. He earned his B.A. in Linguistics at Northwestern University, where he researched syntactic and semantic reanalysis in garden-path sentences. Outside of linguistics, June is an R enthusiast and enjoys blogging about data visualization.

Sophie Faircloth

Senior & M.A. student


Sophie is currently pursuing Bachelor's and Master's degrees in Linguistics with a concentration in pragmatics. She is interested in the intersection of sociolinguistics and pragmatics, currently researching the impact of socio-indexical information on the evaluation of socially impactful pragmatic behavior such as sarcasm usage and underinformativeness. Outside of school, she enjoys playing the drums, painting, and performing in UPenn’s musical comedy group, Mask and Wig.
