Viswanathan, Gopal


Dr. Viswanathan is a Research Professor in the MSE department at The Ohio State University, Columbus, Ohio. Dr. Viswanathan did his Ph.D. in Materials Science and Engineering from University of Cincinnati. Prior to joining MSE, he worked as Senior Research scientist at UES/ Air Force research Laboratory, Wright-Patterson Air Force Base, Dayton Ohio. 

Dr. Viswanathan has considerable research experience, both experimental and theoretical in the area of structure/property relationship in structural and energy materials. Specifically, he has initiated and conducted research, both independent and collaborative, in the advancement of Titanium, Nickel and Iron based alloys, intermetallics and High Entropy Alloys. He has decades of experience in analytical electron microscopy techniques in the areas of diffraction, Hi-Resolution Microscopy, HAADF-STEM microscopy and EDS/EELS and X-Ray spectroscopy and image simulation methods.

His experience also includes the use of additive manufacturing and methods for the development of Ti, Ni and compositionally complex alloy (CCA) systems. Dr. Viswanathan’s research is also focused on exploring structure-property relationships in the areas of environment assisted cracking (EAC) in metallic alloys. He has extensive experience working with oil and gas industries in both inshore and offshore applications.

Dr. Viswanathan teaches both undergraduate and graduate level courses in ‘Physical Metallurgy, Mechanical Behavior of Materials and Mechanical Behavior of Crystalline Solids at High Temperatures’.
