Grad Students

Greg Dachner

Greg Dachner studies the visual information available to pedestrians in human crowds and how that guides locomotor behavior and crowd navigation. Using a combination of virtual reality, motion capture, and computer modeling, he demonstrates the movement dynamics of an individual in a crowd is dependent on what they can see. Before coming to Brown, he received his B.S. in Cognitive Science from the University of California, Merced.

Trenton Wirth

Trenton Wirth's current research concerns the experimental investigation of local neighborhood networks in human crowds. Before coming to Brown, he received his B.S. in Psychology and B.A. in Philosophy from the University of Cincinnati.

Brittany Baxter

Brittany Baxter is interested in the optimized outcomes during obstacles avoidance (e.g. total path length) and the visual information guiding such behaviour. She is currently investigating the influence of barriers, obstructing the travel path en route to a goal. The Dynamical Model of Online Steering (more can be found under the Research tab) includes obstacle avoidance of poles; the desire is to expand this to appropriately include barriers. Before coming to Brown, she received her MSc in Kinesiology and her BSc in Biology and Psychology at Wilfrid Laurier University, Canada.

Joey Bai

Jiuyang Bai studies microscopic models of pedestrian following using computer simulation and behavioral experiment in virtual reality. He is particularly interested in the phase transition of behavior dynamics as a function of crowd density. He received his B.S. in Psychology from Zhengzhou University in China, and M.S. in Cognitive and Behavioral Sciences from Illinois State University (mentored by J. Scott Jordan).

Postdoctoral Fellows

Max Kinateder

Max Kinateder

Max Kinateder works on evacuation behavior (e.g., during tunnel or building fires). The aim of his work is to contribute to a better understanding of perception and action in emergency situations and on how we can create safer environments through design and training measures. For most of his studies, he uses immersive virtual reality (VR) to simulate emergency scenarios. Before working at Brown, he was a guest researcher at the National Institute of Standards and Technology (NIST). He holds a PhD in psychology from the University of W├╝rzburg, Germany.
