Alexandre_Chorin--James_Van_Gundia_Neel

Alexandre Joel Chorin (born 25 June 1938) is an American mathematician known for his contributions to computational fluid mechanics, turbulence, and computational statistical 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, the projection method, and vortex methods. He has made numerous contributions to turbulence theory. In recent years he has been developing methods for prediction in the face of uncertainty and for filtering and data assimilation.
