A professor who builds things.
I teach mechanical engineering at Rajalakshmi Institute of Technology in Chennai and run HEXAIND Technologies. My Ph.D. is in thermal engineering, and my research is now moving into computational fluid dynamics with OpenFOAM and, more recently, computational quantum computing.
I joined Rajalakshmi Institute of Technology in 2026 after four years at Madanapalle Institute of Technology & Science. My Ph.D. from Anna University studied rapeseed-oil biodiesel in a low-heat-rejection diesel engine, and combustion and emissions stay close to my work. Outside the classroom I have also run an institution’s website, Google Workspace and Microsoft 365 as its developer and IT admin. HEXAIND, which I have run since 2020, is where the software side of my work lives; over the years I have built and hosted more than a hundred websites and business applications.
Previously Assistant Professor at Madanapalle Institute of Technology & Science (2022–26) and S.A. Engineering College, Chennai (2017–22), and earlier posts in mechanical and aeronautical engineering since 2009.
Ph.D. Thermal Engineering, Anna University (2021) · M.E. Thermal Engineering, gold medal (2012) · B.E. Aeronautical Engineering (2009)
