Associate Professor, Computer Science, Ph.D.

Doga Demirel, Ph.D.

I earned my Ph.D. in Computer Science from the University of Arkansas at Little Rock (UALR), where I completed my thesis on design and development of virtual interactive simulations for surgical training. I received an M.Sc. in Computer Science from the University of Central Arkansas (UCA) and a B.Sc. in Computer Science from UALR. During my time at UCA and UALR, I had the pleasure of working in the Virtual Reality, Simulation, Imaging and Modeling (ViRaSIM) Lab at UCA.

Currently, I am an Associate Professor and the Assistant Chair in the Department of Computer Science at Florida Polytechnic University. Also, I am the founder and director of the Virtual Reality, Interactive Simulation, and Biomedical (VRISB) Lab at Florida Poly.
