Grigory Barenblatt

Grigory Barenblatt Isaakowitsch (Russian Григорий Исаакович Баренблатт; * July 10, 1927 in Moscow ) is a Russian applied mathematician.

He is the son of the virologist Nadezhda Veniaminovna Kagan, who developed a vaccine against encephalitis and in a laboratory accident itself infected and died, and the Moscow endocrinologist Isaac Grigorjewitsch Barenblatt, author of a widely issued Therapeutic Handbook. His grandfather is the mathematician Veniamin Kagan.

Barenblatt studied at the Moscow State University ( Mekmat ) with the completion in 1950 and his doctorate in 1953 with Andrei Kolmogorov. In 1957 he qualified as a professor at the Moscow State University (Russian PhD ) and was awarded the 1962 title of professor. After completing his PhD, he conducted research at the Institute of Petroleum of the Soviet Academy of Sciences and in 1961 he was Head of plasticity theory at the Institute of Mechanics of Moscow State University. 1975 to 1992 he headed the theoretical division at the Institute of Oceanology of the Soviet Academy of Sciences. 1992 to 1994 he was GI Taylor Professor of Fluid Dynamics at the University of Cambridge, from 1994 as Professor Emeritus.

He was 1990 Visiting Professor at the University of Paris VI, 1991 and 1994 Visiting Professor at the University of Minnesota ( 1994 Hill Professor ), 1992 at the University of Rome ( Tor Vergata ), 1993 and 1995/ 6 at the Autonomous University of Madrid, 1995 the University of Illinois at Urbana -Champaign, 1996/97 Timoshenko visiting professor at Stanford University and the University of California, Berkeley. From 1997 he was at the Lawrence Berkeley National Laboratory and at the same time professor at Berkeley.

It dealt among other things with hydrodynamics in porous media (for example, two-phase flow, oil, gas, groundwater in fractured rock), fracture mechanics, continuum mechanics, not classical media such as polymers and turbulence. With Yakov Borisovich Seldowitsch he worked for a long time, for example, via self-similar solutions and intermediate asymptotics together ( with applications in the theory of combustion and explosions and spreading of thin films ). It was in this context, co-editor of the Collected Papers of Seldowitsch.

He is a member of the American Academy of Arts and Sciences, the National Academy of Engineering, the Academia Europaea and the National Academy of Sciences. He is a Fellow of the Royal Society (2000) and of Gonville and Caius College, Cambridge. In 1993 he received an MA (Master of Arts) in Cambridge.

In 2005 he received the Timoshenko Medal, 1995 Modesto Panetti price, 1999, the GI Taylor Medal of the American Society of Engineering Science, 1995, Lagrange Medal of the Accademia dei Lincei and 1999, JC Maxwell Medal of the International Congress of Industrial and Applied Mathematics. Barenblatt an honorary doctorate from the Royal Swedish Institute of Technology in Stockholm and the Turin Polytechnic. He is a member of the Polish Society of Theoretical and Applied Mechanics and the Danish Centre for Applied Mathematics and Mechanics.
