Professional Profile

Dr. Nirmal Govindaraju is a Research Assistant Professor in the School of Materials Science and Engineering at Oklahoma State University. Dr. Govindaraju's research background and experience are in studying the synthesis-structure-property relationships in thin films and nanomaterials. He has experience in designing and building electrical and thermal property characterization systems, and is currently delving into optical properties of nanomaterials. To date, Dr. Govindaraju's research encompasses the synthesis and characterization of wide bandgap semiconductors (principally diamond and AlN) for high temperature, high power and radiation hard electronics, development of thermal management technology for power electronics, nanomaterials for biological and chemical agent detection, nanomaterials for biological imaging and drug delivery, and high density energy storage materials. He also has a background in analytical modeling and finite element simulations. Dr. Govindaraju has mentored more than fifteen undergraduate and graduate students, and postdoctoral scholars.
