Assistant Professor

Department of Computer Science

Colorado State University, USA.

Dr. Mohammed Safayet Arefin is an Assistant Professor in the Department of Computer Science at Colorado State University (CSU). Dr. Arefin's research concentrates on studying algorithms, technologies, perceptual mechanisms, and human visual systems to understand better the spatial perception of real and simulated virtual objects in real, augmented, and virtual environments. His research investigates the elements and constraints that create spatial perceptual biases in the extended reality (XR) system. Dr. Arefin's research's principal goal is to allow the user to fully utilize the capability of extended reality with effortless, precise, and acceptable user perceptual experiences.

Dr. Arefin has been active in the premier augmented and virtual reality conferences. He has served as a Publication Co-chair in the IEEE Virtual Reality (VR) and IEEE International Symposium on Mixed and Augmented Reality (ISMAR) conference committees for seven successive terms. In addition, Dr. Arefin is co-founder and co-organizer of the workshop on Replication in Extended Reality (WoRXR), mainly held in ISMAR.

Before joining Colorado State University, Dr. Arefin was a Postdoctoral Fellow at the DEVCOM US Army Research Laboratory West (ARL West). Dr. Arefin achieved his Ph.D. and MS in Computer Science from Mississippi State University in 2022 and 2020, respectively. He obtained his bachelor's degree in Computer Science and Engineering from Chittagong University of Engineering & Technology (CUET), Bangladesh. Besides professional work, Dr. Arefin enjoys traveling with his family and playing video games with his friends.
