Biography

Dr. Mohan is currently a professor of Nanoengineering in the Department of Nanoengineering, at North Carolina A&T State University (NCAT) leading computational nanoengineering research. He is also an Adjunct Professor of Nanoscience at Joint School of Nanoscience and Nanoengineering, and is an affiliated professor with Computational Science and Engineering Graduate Program. Dr. Mohan’s research and educational activities have been continually funded over the years by several US federal agencies, defense industries and private organizations. Over the years at NCAT, building upon his core research field of mechanics and materials, Dr. Mohan has led and established new research directions and capabilities, which includes Additive Manufacturing (AM) equipment and infrastructure for hierarchical material developments and research investigations, high performance computational systems, and low length scale mechanical characterization. In addition, Dr. Mohan played a key leading role in the development and establishment of two graduate programs (Computational Science and Engineering, Nanoengineering) at North Carolina A&T State University. He is recipient of 2012 University Senior Researcher Award and 2017 Interdisciplinary Team Research Award at NCAT. Dr. Mohan has a clear understanding and vision for interdisciplinary, system of systems solutions needed for complex problems based on his educational and research upbringing and philosophy.

Dr. Mohan has more than 140 peer reviewed journal articles, book chapters, and conference proceedings to his credit to date. Prior to NCAT, he served as a composites materials expert for NASA National Center for Advanced Manufacturing at University of New Orleans; as a resident research scientist with U.S. Army Research Laboratory (ARL). Dr. Mohan holds a Ph.D. in Mechanical Engineering from University of Minnesota, a M.S. in Theoretical and Applied Mechanics from University of Illinois at Urbana-Champaign. His computational methods for physics based flow modeling of composite material processes evolved into DOD HPCMP scalable parallel simulation analysis software for liquid composite molding (LCM) processes; provided modeling and simulation analysis capabilities to various advanced composite prototype developments for the Department of Defense. These had resulted in two U.S. Army R&D Achievement Awards for ARL. Dr. Mohan’s research in his foundational core of mechanics and materials, contributions and interests include the areas mechanics, materials, and computational modeling of nanoengineered material systems (crystalline, polymer composites, amorphous, bio and cementitious material systems and their multi-scale effects); modeling of bio and nano systems, interfaces, and interactions; computational mechanics, nanomechanics, and material sciences; material science and mechanics related to Additive Manufacturing (AM) of Hierarchical Material Systems and AM structures; transport phenomena in composite material processing; physics based composite modeling simulations, understanding uncertainties and process optimizations, experimental investigations for LCM processes; high performance scalable computing, engineering product visualization; engineering education.

Dr. Mohan is an invited and keynote speaker at several international conferences, universities, research laboratories, and industries in US, Europe, India, Brazil, Taiwan, S. Korea, Malaysia, and several other countries. Dr. Mohan also holds a visiting professorship with University of Malaysia, Pahang. His industrial interactions include Lockheed Martin-Manassas, Boeing-Mesa, Northrop Grumman, Boeing-St. Louis, Lockheed Martin-Skunk Works, General Dynamics, Highland Industries, Advaero Technologies, Callaway Carbon, and VX Aerospace. Dr. Mohan plays an active role in American Society for Mechanical Engineers (ASME) where he initiated and served as the Track Chair for Materials: Genetics to Structures Track at the 2014, 2015 ASME International Mechanical Engineering Congress and Exposition; Chair of the ASME materials processing technical committee, and is currently serving in the executive leadership as vice chair for nanoengineering council and nanoengineering for energy and sustainability group. He is a member of American Society of Aeronautics (AIAA), American Society for Engineering Education (ASEE), and Society for Advancement of Materials and Process Engineering (SAMPE); regularly presents, organizes and conducts seminars and conferences for these professional and engineering organizations in US and around the world.
