Alfred P. Sloan Research Fellowship (2010) Vasil A. Popov Prize (2010) Joel Aaron Tropp (born July 1977 in Austin, Texas) is the Steele Family Professor of Applied and Computational Mathematics in the Computing and Mathematical Sciences Department at the California Institute of Technology.

[3] In his early research,[4] Tropp developed performance guarantees for algorithms for sparse approximation and compressed sensing.

[7] In 2010, he was awarded an Alfred P. Sloan Research Fellowship in Mathematics,[8] and he received the Sixth Vasil A. Popov Prize in approximation theory for his work on Matching Pursuit algorithms.

[4] He won the Eighth Monroe H. Martin Prize in applied mathematics in 2011 for work on sparse optimization.

[10] In 2019 he was named a SIAM Fellow "for contributions to signal processing, data analysis, and randomized linear algebra".
