Dr. K.M. Kumar is an Assistant Professor in the department of Mechanical Engineering atIndian Institute of Technology Indore. He received his B. Tech degree in Mechanical Engineering from Jalpaiguri Government Engineering College, in 2010 and M. Tech degree in Mechanical Engineering with Machine Design specialization from Indian Institute of Technology Guwahati, in 2012. He was awarded Ph.D. degree from Indian Institute of Science in 2019 for his thesis entitled “Direct Estimation of Acoustic Source Characteristics of the Internal Combustion Engine Exhaust System and Analysis of Complex Muffler Configurations.”

During his Ph.D., he has worked as project assistant on 5 industrial consultancy projects related to design and analysis of automotive and DG set silencers/mufflers. After his Ph.D. thesis submission, he worked on 3industrial consultancy projects as co-consultant with Prof. M. L. Munjal of Indian Institute of Science, Bengaluru. In 2018-19, Dr. Kumar delivered lectures as a co-instructor with Prof. Munjal on Acoustics of Ducts and Mufflers and Industrial Noise Control to train the practicing engineers of Faurecia Clean Mobility Centre, Bengaluru. He has published several papers in peer-reviewed international journals as well as conferences. His research interests are Acoustics of Ducts and Mufflers; Automotive Noise and Vibration Control; Industrial Noise and Vibration Control; and Designing for Quietness
