Prof. M.P. Singh, a Fulbright Scholar, earned Ph.D. from University of Maryland, USA after which he joined the Cornell University where he worked in the 60s followed by 1-year stint at NASA.

On returning to India, Prof. M.P. Singh was one of the founding faculty members of the prestigious IIT–Delhi. At his initiative, a Centre for Atmospheric Sciences was set-up at IIT Delhi; today it is the leading research center of the country well known internationally for its work in climate research, cyclone prediction and air quality modeling. Prof. Singh has supervised 27 PhDs and has published over 100 research papers in journals of International repute. He is the co-author of the book, (written jointly with Prof. Sethu Raman) titled “Dynamics of Atmospheric Flow” published under the ‘Advances in Fluid Mechanic Series, UK’. He has been one of the Guest Editors of the special issues (on Air Quality) of the prestigious international journal “Atmospheric Environment” which appeared in 1991 and 1995. He had been on the Editorial Board of the journal “Atmospheric Environment” (1988–94); “Non-linear World” (1992 -96) and “Advances in Fluid Mechanics Series” under the aegis of Computational Mechanics Publications, UK (1994 – 1998). The prestigious journal, “Pure and Applied Geophysics”, (PAGEOPH, a Switzerland based journal) has brought out a special edition - a book entitled “Weather and Climate: The M.P. Singh Volumes I & II”, in honor of Prof. M.P. Singh with leading experts from all over the world as contributors. Recently, a book entitled “Air Quality”, a PAGEOPH Topical Volume with Prof. Singh as one of the guest editors of the prestigious publication by Birkhauser Verlag, Basel. Boston. Berlin has appeared in early 2003.

Prof. M.P. Singh directed several International conferences & workshops on topics related to Environment in India, Italy and Brunei. At AIT, he has provided leadership to organize three International Conferences, one on Industry - Academic Interaction and the other two on Nanotechnology in 2006, 2007 and 2009 respectively. The proceedings of Nanotechnology Conference, after peer review, have been brought out in special issue (s) of the prestigious "International Journal of Nanotechnology" and the proceedings of 2009 Conference would also be brought out in a special issue of the prestigious International Journal of Nanotechnology.

Prof. Singh was a visiting Professor at Cambridge University (for one year) in 1973. He has been a Visiting Professor at several Universities including University of Alabama, USA; University of Brunei; University of Calgary, Canada; University of Kuwait; University of Reading, UK; National Institute of Informatics & Automatics, Paris, France; National Institute for Research & Environment, Japan. Prof. Singh has visited China & Poland as a guest of the respective Academies.

Prof. Singh has played a trail-blazing role in developing multidisciplinary programs in the country. He represented India in the scientific delegation to the then Soviet Union in 1988 and in the Indo-US Sub-commission on Science & Technology in 1985 and 1987. He was a member of the Indian delegation to attend the prestigious Science & Technology initiative meet in 1983, the so-called Blue Ribbon Panel on Meteorology set up by the then Indian Prime Minister, Mrs. Indira Gandhi and then US President, Mr. Ronald Reagan. He was a member of ICSU International Committee for the International Decade for Natural Disaster Reduction during 1990-92.

Other Contribution: After retirement from IIT - Delhi, Prof. M.P. Singh has been spearheading Ansal Institute of Technology, Gurgaon as its founder Director since 2000. Today, Ansal Institute of Technology is a leading Institute in the country to provide higher education in professional fields. It has established International reputation for its US based collaborative education.
