Dr Anna Leshinskaya
Dr Anna Leshinskaya is an Assistant Professor at the Department of Cognitive Sciences and Fellow at the Center for Neurobiology of Learning & Memory at UC Irvine, as well as an affiliated researcher with the AI Objectives Institute. She directs the Relational Cognition laboratory.
She earned a PhD in Cognitive Psychology from Harvard University in 2015. Her background and interests are in human cognitive neuroscience and computational cognitive science. She is broadly interested in the computational principles underlying the learning and representation of concepts and relations and how these are supported by both artificial and natural neural networks. Her recent work uses interpretability techniques to measure cognitive alignment between humans and large language models.

Matthew Shinkle
POST-DOC FELLOW
Matthew is a postdoctoral researcher in the RelCog Lab, researching mechanisms of moral cognition in large language models and humans. He holds a PhD in neuroscience from the University of Nevada, Reno, where he studied how deep neural networks can be used as computational models of the human visual system.
Em Smullen
GRADUATE STUDENT
m.smullen@uci.edu
Em is a first-year PhD student in the Cognitive Science department. They study abstraction, relational reasoning, and concept representation in both human and artificial minds. Em is also interested in merging computational, philosophical, and psychological methods to understand the cognitive processes underlying moral judgment. Outside of lab, they can be found reading existentialist texts, lying in the grass, or producing odd performance art.

Siwen Lucy Xie
Lucy is a first-year PhD student in the Cognitive Science department. She received her Bachelor's degrees in Artificial Intelligence and Psychology from Peking University. She is interested in using computational models to explore mysteries in the human mind, while also drawing inspiration for machine intelligence. Outside of academia, she enjoys reading and writing fiction, as well as making anime music videos.

Om B. Bhatt
Om is a research technician and lab manager at the RelCog Lab. He comes to UCI from Georgia Tech, where he earned an MS in Computer Science along with research exposure to LLM evaluation and neuroAI methods. He in interested in using language models as testbeds for theories of morality and social reasoning, as well as how neural data could inform our understanding of knowledge representation in models.
Seong Hah Cho
RESEARCH COLLABORATOR
seonghahcho@gmail.com
Seong is a researcher exploring how Large Language Models represent and process moral decisions, applying methods from mechanistic interpretability and cognitive science. He holds a Ph.D. in Psychology from the University of Hong Kong and currently works as a Data Scientist at a non-profit organization supporting smallholder farmers in Myanmar.

Rylen Choi
Rylen is a first-year Cognitive Sciences major excited to explore how abstractions in mental phenomena (i.e. bias, heuristics, ideology) can be interpreted by and applied to artificial intelligence. During her time at the Relational Cognition Lab, her aim is to develop her technical research skills as well as her conceptual knowledge of relational structures and cognitive frameworks. She is very thankful for this opportunity!
