Andrew McAvan

Graduate Student
Research Area:

Human spatial navigation and decision making in non-Euclidean VR spaces.

I am interested in studying how humans navigate and make decisions in non-Euclidean spaces. To achieve this, I develop experiments using the Unity 3D game engine in conjunction with cutting-edge VR technology. I did my undergraduate studies at the University of Arizona, where I worked with multiple labs assessing not only retention rates of children in the Pima County DES system, but also exploring how humans react to stress. Post undergrad I worked at an in-patient rehabilitation facility for individuals with substance abuse and mood disorders, followed by the Human Spatial Cognition Lab at the University of Arizona. In my free time, I enjoy playing games of all kinds (tabletop, video, etc.), exploring nature, and creating things.
