Samuel A. Nastase

Principal Investigator
Assistant Professor of Psychology and Neuroscience
Co-director, Center for Computational Language Sciences

Sam is an Assistant Professor in the Department of Psychology and the Neuroscience Program at USC, as well as director of the Shared Minds Lab. His research focuses on understanding what is shared across individual brains and how we use language to share our thoughts with one another. His expertise combines naturalistic neuroscience (e.g., fMRI, iEEG) and deep learning (e.g., large language models) to better understand how the brain supports communication in real-world contexts. Sam completed his PhD with Jim Haxby at Dartmouth and worked with Uri Hasson and Ken Norman as a postdoc at Princeton.

Sajjad Torabian

Postdoctoral Scholar

How do we build representations of others? How do we think about their goals, intentions, and beliefs, and communicate what we build in our minds? In my PhD at UC Irvine, I tackled these questions by designing controlled visual fMRI experiments. Specifically, I studied how the brain categorizes representations of physical versus social events, and how it transitions between the two through degrees of intentions. During my postdoc at USC, using naturalistic experiments and deep learning models, I now investigate how the brain transforms visual stimuli into structured context during social interaction, bridging perception, language, and social cognition.

PhD Student

April’s research focuses on computational psychiatry and the use of large language models to analyze brain signals during naturalistic conversation. She is also interested in brain–computer interfaces, particularly speech BCIs. Outside of the lab, she enjoys snowboarding.
