Dr. Subhradeep Roy is a tenure-track Assistant Professor in the Department of Mechanical Engineering at Embry–Riddle Aeronautical University.

Dr. Roy received his Bachelor's and Master's degrees in Mechanical Engineering from the Indian Institute of Engineering Science and Technology, Shibpur in 2010 and the Indian Institute of Technology Kanpur in 2012, respectively, and a Ph.D. in Engineering Mechanics from Virginia Tech in 2017. From 2017-2019 he was a post-doctoral scholar in the Physical Computing Laboratory at Virginia Tech. From 2019-2021, he held a tenure-track assistant professor position in the Mechanical Engineering Department at California State University, Northridge.

His overarching research goal is to study interactions in complex systems by collaborating with researchers from various disciplines. He directs an interdisciplinary 'Complex Dynamical Systems Laboratory' and works on various topics, including bat swarms to vehicular traffic congestion. As a teacher, his interests cover undergraduate and graduate-level mechanics education. He aims to prepare future engineers and equip them with skills to tackle issues related to complex systems by incorporating research into courses and engaging them in his research.

He was the recipient of the National Science Foundation CAREER Award in 2023.
