[[File:Nikhilmore IISc Bangalore india.jpg|thumb|180px|left|Indian Institute of Science]]
M. L. Munjal, born on 4 April 1945 in the Indian state of [[Punjab, India|Punjab]], graduated in mechanical engineering with honors in 1966 from [[Panjab University]] and a master's degree in internal combustion engineering with distinction from the [[Indian Institute of Science]] (IISc) in 1968.<ref name="M. L. Munjal on INAE">{{Cite web |url=http://inae.in/expert-search/index.php/m-l-munjal |title=M. L. Munjal on INAE |date=2017 |publisher=Indian National Academy of Engineering}}</ref> He joined IISc as a member of faculty in 1968, simultaneously pursuing his doctoral studies and earned his PhD in 1971. He served IISc in many positions: chairing the department of mechanical engineering during 1991–94, the division of mechanical sciences from 1999 to 2005, and serving as the convener of the ''Chairmen of Divisions'' from 2003 to 2005.<ref name="Indian fellow" /> In between, he had three positions abroad as a visiting faculty member. In 1979, he served at [[Technische Universität Berlin]] for a year. From 1986–87, he worked at [[University of Calgary]] and Nelson Industries in Wisconsin. Then in 1994–95 he served as a visiting scientist at [[Ford Motor Company]] at their Michigan centre. Post-retirement, he served as an honorary professor, [[Indian National Science Academy|INSA]] senior scientist and at the ''Facility for Research in Technical Acoustics'' (FRITA) of the Indian Institute of Science.<ref name="Emeritus Professor & AICTE Distinguished Chair Professor" />

Munjal lives in [[Bengaluru]], [[Karnataka]].<ref name="NASI fellows" />
