Dr. R. Kannan currently serves as Associate Professor at the Department of Aerospace Engineering, School of Engineering, Amrita Vishwa Vidyapeetham, Coimbatore Campus.

Kannan‘s research focuses on harnessing the effect due to the interaction of the fluid flow with micro and nanostructured asperities present solid surfaces for various engineering applications such as Liquid Atomization,  Biologically Inspired Anti-icing Surfaces, Thermal Barrier Coating, Corrosion Control, etc. In addition to this, focus on the development of ultra light weight highly efficient combustor for Gas Turbine Combustor, Afterburner, Ramjet, and Scramjet Engine.

Prior to starting his career as Assistant Professor (SG) at Amrita on 2016, he was with the University of Toronto, Canada (2011 – 2013) as a Post-Doctoral Fellow. He received his Ph. D in Aerospace Engineering from Indian Institute of Science (IISc. 2012) Bangalore after studying his M. Tech in Aerospace Engineering from Indian Institute of Technology (IIT, 2002) Kanpur and B. Tech in Aeronautical Engineering (2000) from Madras Institute of Technology, Anna University Chennai. He is currently supervising one research student for the award of the Ph. D degree. His teaching interest is in the field of High-Speed Flows, Propulsion, and Combustion.

His research interests include Atomization and Characterization of liquid jets and sprays, Biologically inspired Anti-icing and self-cleaning surfaces, Extraction of Bio-oil and Bio-gas from Biomass Composite, Corrosion Control using Superhydrophobic Surfaces, New Combustor Technology Development for Gas Turbine, Afterburner, Ramjet, and Scramjet.
