Leonid "Leo" Khachiyan joined Rutgers Department of Computer Science in 1990, where he served as a member of the faculty until his passing in 2005. In 1979, he gained recognition throughout the mathematics and computer science communities by establishing an effective polynomial time algorithm for linear programming. This breakthrough served to advance the field of linear programming, and as such, led to him being awarded the Fulkerson Prize in 1982 from the Mathematical Programming Society and American Mathematical Society.
