at that time. His research interests are in developing methods for the control and estimation of nonlinear dynamical systems and stochastic processes. In 1988 he founded the SIAM Activity Group on Control and Systems Theory and was its first chair. He was again chair of the SIAG CST in 2005–07. In 2012, he received the

In his PhD dissertation, Krener showed that the

Lie bracket In mathematics, a Lie algebra (pronounced ) is a vector space \mathfrak g together with an operation called the Lie bracket, an alternating bilinear map \mathfrak g \times \mathfrak g \rightarrow \mathfrak g, that satisfies the Jacobi identit ...

played an important role in nonlinear controllability by proving a time directed version of Chow's theorem. Several years later with Hermann, he gave the definitive treatment of controllability and observability for nonlinear systems. This work was later cited by the

as one of Twenty Five Seminal Papers in Control, published in the twentieth century, which have made a major impact on the field of control. With Isidori, Gori-Giorgi and Monaco, he gave conditions for the existence and construction of decoupling and noninteracting control laws for nonlinear systems. This paper won the George S. Axelby Outstanding Paper Award from IEEE Transactions on Automatic Control and Krener received the Medal of the University of Rome for his contributions. It also led to the concept of the zero of a nonlinear system, which was subsequently developed by Byrnes and Isidori and extended to the
