Karna was born in Bihar in 1956. He received his Ph.D. and an M.Sc. degree in chemistry from Banaras Hindu University, India and B.Sc. degree in math, physics, and chemistry from Bhagalpur University in India. He has authored/coauthored over 300 articles including refereed technical papers, conference proceedings, reviews, and book chapters. He has co-edited few books including "DoD Applications of Nano-materials".
Karna conducts basic and applied research in nanomaterials, mentors young scientists and engineers, identifies critical science and technology areas in nanoscience relevant to Army technologies and work with Army S&E and senior leadership to develop relevant program, identify and recommend to management chain R&D leveraging opportunities within and outside of the U.S. Department of Defense. The main focus of his research is a fundamental understanding of the structure and quantum-size properties of nano-materials and their applications in Army technologies.
