Alexandre Joel Chorin(born 25 June 1938) is an American mathematician known for his contributions tocomputational fluid mechanics,turbulence,and computationalstatistical mechanics.
Chorin's work involves developing methods for solving physics and fluid mechanics problems computationally. His early work introduced several widely used numerical methods for solving the Navier-Stokes equations, including the method of artificial compressibility,[1]theprojection method,[2]and vortex methods.[3]He has made numerous contributions to turbulence theory.[4]In recent years he has been developing methods for prediction in the face of uncertainty[5]and for filtering and data assimilation.[6]
Early life
[edit]Chorin was born on 25 June 1938 inWarsaw,Poland. Born just one year before Hitler's invasion, his family fled Poland throughLithuaniaandRussiabefore spending 10 years living inIsraeland 11 years living inSwitzerland.Chorin came to the United States at 23 for graduate studies, nurturing his interest in fluid dynamics by working on the equations responsible for predictingocean tides.[7]
Career
[edit]Chorin is aUniversity Professorat theUniversity of California,a Professor of Mathematics at theUniversity of California, Berkeley,and a Senior Scientist at theLawrence Berkeley National Laboratory.
Chorin received theIng. Dipl.Physics degree from theEPFL(École Polytechnique Fédérale de Lausanne) in 1961, an M.S. in Mathematics from New York University in 1964, and a PhD in Mathematics fromNew York Universityin 1966. Chorin stayed at New York University as a researcher at theCourant Institute of Mathematical Sciencesuntil 1969 when he was promoted to assistant professor and then associate professor the following year.
Chorin is widely recognized for his mentoring of graduate students[8]and postdoctoral fellows, many of whom have become nationally and internationally recognized scientists in their own right. In 2008 he was honored with the Sarlo mentoring award by theUniversity of California, Berkeley.[9]
Awards
[edit]Chorin's awards include the National Academy Award in Applied Mathematics and Numerical Analysis (1989), the Norbert Wiener Prize of the American Mathematical Society and the Society for Industrial and Applied Mathematics (2000),[10]the Lagrange Prize of the International Council on Industrial and Applied Mathematics (2011) and theNational Medal of Science(2012).[11][12]He is a member of the USNational Academy of Sciencesand a fellow of theAmerican Academy of Arts and Sciences,theSociety for Industrial and Applied Mathematics,and theAmerican Mathematical Society.
