The SIAM Activity Group on Control and Systems Theory Prize (SIAG/CST Prize) is awarded every two years to one outstanding early career researcher for distinguished contributions to mathematical theory of systems and control in the three calendar years preceding the award year.

The candidateâ€™s research must contain significant contributions to the mathematical theory of control or systems, as commonly defined in the mathematical and engineering literature. One key paper must be cited as evidencing the contributions, though a body of papers may be discussed in the nomination. The qualifying key paper must have been published in English in a peer-reviewed journal within the three calendar years preceding the award year. Either the candidate must be a graduate student or the key paper must have been published no more than three years after the candidate received their PhD.

The prize will next be awarded at the 2021 SIAM Conference on Control and Its Applications.

The Chair of the SIAM Activity Group on Control and Systems Theory will present the award to the recipient. An announcement of the award recipient(s) will appear in *SIAM News* and the activity group's newsletter.
