Eugene Paul Gross (27 June 1926 – 19 January 1991) was a theoretical physicist and Edward and Gertrude Swartz professor at Brandeis University, known for his contribution to the Bhatnagar-Gross-Krook (BGK) collision model used in the Boltzmann equation and in lattice Boltzmann methods and to the Gross–Pitaevskii equation which describes the ground state of a quantum system of identical bosons.
[1] Gross was Carnegie Fellow at Harvard from 1948 to 1949 and research associate at the Massachusetts Institute of Technology from 1950 to 1951.
Subsequently, until 1954, he was a staff member at the Laboratory for Insulation Research and from 1954 to 1956 assistant professor at Syracuse University.
From 1963 to 1964 he was a Fulbright Scholar at the University of Rome in Italy, and from 1969 to 1970 visiting professor at the Massachusetts Institute of Technology.
With Prabhu L. Bhatnagar and Max Krook, Gross introduced the Bhatnagar–Gross–Krook operator in a paper in Physical Review in 1954.
