Dr. K. A. Subramanian is working as a Professor and currently the Head of the Department of Energy Science and Engineering, Indian Institute of Technology Delhi, and former Head of the Centre for Energy Studies from 2019 to 2021. After he completed his Ph.D. from the Department of Mechanical Engineering, IIT Madras, he worked as a Scientist at the Indian Institute of Petroleum, Dehradun.

His main research area includes Hydrogen Energy, Alternative fuelled internal combustion engines/vehicles, Hydrogen Backfire and combustion, Hydrogen Fuel Cell, Oxy-combustion, Biofuels and Engines, Zero emission vehicles, Hybrid Energy Systems, and Integrated Energy Systems. He is one among the Top 2% Scientist by Stanford University, 2020 in the world. He has completed several sponsored research projects in alternative-fuelled internal combustion engines/vehicles.

He has recently developed the technology for the utilization of hydrogen in spark-ignition engines for electrical power generation, and Dimethyl Ether fuelled Engines / Vehicles with the collaboration of oil and original engine manufacturers. He has also developed Alcohol fuelled engines, Biogas vehicles, DME-fuelled engine/vehicle, Dual-fuel engines (Hydrogen-Diesel, CNG-Diesel, Biogas-Diesel), and Energy efficiency improvement using Oxy-combustion. He developed many numbers of courses including Hydrogen Energy, Zero Emission Vehicles, Bioenergy: Resources, Technologies and Assessment, Carbon Capture and Storage and Organic Waste to Energy Conversion Technology. He has guided several doctoral (Ph.D.) scholars and published several research papers in reputed Journals. He has filed two patents so far. He is the author of the book 'Biofueled Reciprocating Internal Combustion Engines' and co-author of another book 'Alternative Transportation Fuels: Utilization in Combustion Engines' published by CRC Press (Taylor & Francis Group).
