    Alok Krishna Gupta was born in a small mining town called Sanctoria in Burdwan District of West Bengal. Following completion of his bachelor and master degree at Jadavpur University, Calcutta, he got his doctor’s degree at the University of Pittsburgh, U.S.A. Here he had the good fortune to study Experimental Petrology under the tutelage of Professor Kenzo Yagi of Hokkaido University (Japan), Who had developed a small Experimental Petrology Laboratory at Pittsburgh, where young Alok learnt about rudiments of Phase Equilibria study from Professor Yagi, who taught him details of experimental techniques as developed by Norman Bowen, Frank Schairer and Hatten S. Yoder. Following Kenzo’s instruction, Alok visited Geophysical Laboratory a number of times and was inspired by Yoder and Schairer. After spending six years as a Pre- and Post-doctoral Fellow at Pittsburgh, he continued his Post-doctoral studies at the University of Western Ontario (Canada), Ruhr University (Germany), Hokkaido University, Japan, Melbourn University, Australia and University of Tasmania, Australia, for another ten years to conduct his studies respectively under W.S. Fyfe, N.D. Chatterjee, Kenzo Yagi , John Lovering and David H. Green. This enriched his knowledge of alkaline rocks to a great extent. Later, he visited University of Texas (Dallus), for two months and University of Bristol for three months on a Royal Society Fellowship to do collaborative study with Professor Presnall and B.J. Wood. He led a delegation of Indian Petrologist to Chernogolovka Institute of Experimental Petrology, USSR to conduct collaborative study with Russian Scientists. Five Russian Scientists visited National Centre of Experimental Mineralogy and Petrology for several months and conducted collaborative research with scientists of this institute.

 

    He is married to Chhaya Gupta. Professor Gupta has two sons both in academics. The elder one Sanchayan Neal Gupta is an Organic Geochemist, who after his doctorate degree at Bristol University did his Post-doctorate investigation at Yale, M.I.T. and Geophysical Lab (Washington, U.S.A). He has been working as a Research Scientist and Adjunct Professor at Brayant University, Rhode Island, U.S.A.Younger son Sandeepan Rick Gupta did his Ph.D at Michigan Ann arbor and now has been working as a Post-doctorate fellow at Fisica d’Altes Energies, Barcelona, Spain. Neal is married to Mary Elizabath, where as Rick is married to Aloka Nanda.

    Professor Gupta has proved that leucite reacts with soda-rich fluids to be converted to analcime, or a nepheline-K-feldspar intergrowth to produce pseudoleucite. This study is generally accepted internationally as the cause of the genesis of  pseudoleucite. His study on more than 25 pseudo-ternary, quaternary and quinary systems in presence or absence of fluid under variable P-T conditions, elucidates the genesis of ultrapotassic rocks. He evidenced that the upper mantle is like a fruit cake, which evolved in this manner due to deep subduction of crustal materials into the mantle and these K-rich lavas have been originated due to periodic release of potassium or associated incompatible elements during decompression melting of phlogopite and/or richterite-bearing periodites. He is the senior author of a book, entitled Petrology and Genesis of Leucite-bearing Rocks (Spinger-Verlag). He has authored or edited ten books/volumes related to Earth science. Professor Gupta is the Founding Professor of the Department of Earth and Planetary Sciences, University of Allahabad. He set up the first National Center of Experimental Mineralogy and Petrology in Allahabad and transformed it as a major center of research related to the dynamic processes inside the earth up to a depth of 750 km.

      Professor Gupta is a Fellow of Indian Academy of Sciences, Bangalore and National Academy of Sciences (India), Allahabad (Elected in 1991). Professor Gupta had been Vice-president and secretary of NASI, Allahabad. He is a recipient of Career Award and National Lectureship Award of UGC, Shanti Swaroop Bhatnagar Prize, Rhode Memorial Award, Best Teacher's Award, Birbal Sahni award of Indain Science Congress Association, Raja Ramanna Fellowship of Atomic Energy Commission, and Jawaharlal Nehru Birth Centenary Lectureship Award of the Indian National Science Academy.

    Professor Alok K. Gupta is currently an Emeritus Professor at the National Center of Experimental Mineralogy and Petrology, University of Allahabad. He is deeply interested in English and Bengali Literature and has written a number of Bengali and English novels.
