Alexandra Carstensen
Postdoctoral Research Fellow, Psychology
BioI completed my PhD in psychology at UC Berkeley and postdoctoral research at Radboud University in the Netherlands, and am currently a postdoctoral researcher working with Mike Frank in the Language and Cognition Lab at Stanford University. I'm interested broadly in how humans abstract away from the sensory information they receive about the world to create, structure, and communicate higher-level representations. To better understand these processes, my research explores the nature of category systems across languages: how these semantic structures vary, evolve, and influence thought. In a complementary line of work, I examine the role of language and culture in children's developing conceptualizations of space and relations.

Rajpreet Chahal
Postdoctoral Research Fellow, Psychology
BioRaj received her Ph.D. in Human Development and Designated Emphasis in Translational Research from the University of California, Davis in 2019, where she was a TL1 Pre-Doctoral Clinical Research Training Scholar and supported by the UC Davis School of Medicine and the NIH National Center for Advancing Translational Sciences. In her graduate work, Raj assessed how inter-individual differences in key developmental aspects of adolescence (i.e., puberty, psychopathology, and the brain) inform one another to contribute to our understanding of heterogeneous risk mechanisms and opportunities for targeted interventions. Specifically, Raj characterized associations between pubertal timing, structural and functional network properties in the brain, and internalizing symptoms. Raj also examined topographical signatures in white matter tracts as they reflect the history of depressive symptoms in adolescent girls, and patterns of functional connectivity, revealed by neural biotyping, as they forecast future internalizing symptoms in at-risk adolescents. As a post-doctoral researcher in the SNAP lab, Raj is extending her work by studying the effects of early life stress on the development of large-scale structural and functional brain circuits to understand when and in whom neurobiological alterations arise and confer risk for depression and suicidal ideation. The goal of this research is to guide person-centered approaches to detect vulnerability for, and predict the course of depression.
