Primary Investigator (PI):

William Warren –

William Warren earned his undergraduate degree at Hampshire College (1976), his Ph.D. in Experimental Psychology from the University of Connecticut (1982), did post-doctoral work at the University of Edinburgh, and has been a professor at Brown ever since. He served as Chair of the Department of Cognitive and Linguistic Sciences from 2002-10. Warren is the recipient of a Fulbright Research Fellowship, an NIH Research Career Development Award, and Brown’s Elizabeth Leduc Teaching Award for Excellence in the Life Sciences. Warren’s research focuses on the visual control of action – in particular, human locomotion and navigation. He seeks to explain how this behavior is adaptively regulated by multi-sensory information, within a dynamical systems framework. Using virtual reality techniques, his research team investigates problems such as the visual control of steering, obstacle avoidance, wayfinding, pedestrian interactions, and the collective behavior of crowds. Experiments in the Virtual Environment Navigation Lab (VENLab) enable his group to manipulate what participants see as they walk through a virtual landscape, and to measure and model their behavior. The aim of this research is to understand how adaptive behavior emerges from the dynamic interaction between an organism and its environment. He believes the answers will not be found only in the brain, but will strongly depend on the physical and informational regularities that the brain exploits. This work contributes to basic knowledge that is needed to understand visual-motor disorders in humans, and to develop mobile robots that can operate in novel environments.


Lab Manager:

Hector Taylor –

Hector Taylor (He/Him) is the Lab’s Manager. He comes from Phoenix Arizona, where he received his B.S. in Cognitive Science from Arizona State University. His research interests are in the use of spatial computing to investigate embodiment and perception

Post Doctoral Researchers:

Ben Falandays –

Ben received his PhD in Cognitive and Information Sciences from the University of California, Merced in 2022. His work focuses on understanding human language, communication, and culture from the theoretical standpoint of embodied cognition and ecological psychology.


Graduate Students:

Meghan Willcoxon –

Meghan Willcoxon studies self-organization in local neighborhoods of human crowds using behavioral experiments in virtual reality. Before coming to Brown, she received her B.A. in Cognitive Science at Vassar College.

Zhenyu Zhu –

Zhenyu joined VENLab in 2019 as a PhD student after he got his bachelor degree in neuroscience from NYU Shanghai. At VEN Lab, he is interested in using computational methods and behavioral tasks to study visual motion information used in human locomotion. In his spare time, he enjoys cycling on a good day and binge watching tv shows on a bad day. 

Kei Yoshida –

B.A., Computer Science & Psychology, Coe College, 2020
Kei Yoshida (she/her) studies how collective motion emerges from dynamic local interactions of individual agents. She is particularly interested in how a pedestrian influences the behavior of other pedestrians and how these leader-follower interactions change over time. Before joining the VEN Lab in 2020, she completed her B.A. in Computer Science and Psychology at Coe College.
Kyra Veprek –

Kyra Veprek (she/her) is a second year student in the CLPS Department broadly interested in the intersection between spatial perception and locomotion. Before Brown, Kyra studied visual cognition & attention, as well as studio art, at the University of Massachusetts Amherst
Cassandra Engstrom –

Cassandra Engstrom is a first year PhD student in the VEN Lab. Her interests lie in using mathematics to describe how people behave in complex space, both when first exploring and subsequently revisiting it. Prior to joining CLPS, she earned a MSc in cognitive neuroscience at the Graduate Center (CUNY) and a Bachelor of Architecture from the Cooper Union.
