Subramani "Mani" Sockalingam is an Associate Professor in Mechanical Engineering at the University of South Carolina (USC). Dr. Sockalingam received his PhD from the University of Delaware Center for Composite Materials and Master's from the University of Cincinnati, both in Mechanical Engineering. Additionally, he has six years of industrial experience in the automotive and defense sectors. His technical interests include the dynamic behavior of composite materials, inverse methodologies for high throughput material characterization, novel architectured composite material designs for enhancing structural performance, test methods for evaluating high strain rate delamination, and automated fiber placement manufacturing.

Behrad Koohbor is an Assistant Professor of Mechanical Engineering at Rowan University. Dr. Koohbor received his PhD from the University of South Carolina. Before joining Rowan University in 2019, Dr. Koohbor completed a 2-year postdoctoral fellowship at the University of Illinois at Urbana-Champaign. Dr. Koohbor is interested in understanding the process-structure-property-performance relations in advanced materials and structures. His team uses various measurement techniques to explore the origins of temperature-dependent and rate-sensitive responses of advanced materials and structures at multiple lengths and time scales. He has been a member of ASC since 2015.
