Distinguished Achievement: Recipient of the 2023 NSF CAREER Award

Dr. Subhradeep Roy received his Bachelor's degree in Mechanical Engineering from the Indian Institute of Engineering Science and Technology, Shibpur, in 2010, followed by a Master's from the Indian Institute of Technology Kanpur in 2012. He completed his Ph.D. in Engineering Mechanics at Virginia Tech in 2017. From 2017 to 2019, he worked as a post-doctoral scholar at the Physical Computing Laboratory at Virginia Tech, and between 2019 and 2021, he was a tenure-track assistant professor in the Mechanical Engineering Department at California State University, Northridge. In Fall 2021, he joined the Mechanical Engineering Department at Embry-Riddle Aeronautical University (ERAU), Daytona Beach campus, where he continues to serve as a tenure-track assistant professor.

At ERAU, Dr. Roy directs the Complex Dynamical Systems Laboratory, where his research focuses on understanding complex dynamics in both human-made and natural systems. His work blends interdisciplinary and data-driven approaches to study how local interactions shape overall system behavior, with applications in biologically inspired swarms, brain connectivity networks, and traffic and transportation systems.
