Dr. Venkataraman has been associated with Mahindra university since its inception and its formative years at Mahindra Ecole centrale (MU) since 2014. Prior to joining MU, he has several years of post-doctoral research experience at the Laboratory for surface science and technology, Department of materials (D-MATL), Swiss federal institute of technology (ETH), Zurich, Switzerland. He obtained Ph.D. from the Department of inorganic and physical chemistry, Indian Institute of Science (I.I.Sc), Bangalore. His Ph.D. thesis has been recognized by Dr. A. Nagaraja Rao Medal and Dr. J. C. Ghosh Medal as the best Ph.D. thesis of the year in the division of chemical sciences and in the department of inorganic and physical chemistry. His current research interests are in the areas of surfaces and interfaces, surface modification, patterning and spectroscopy.
