Harold J. Kushner 
 Director of the Lefschetz Center  for Dynamical Systems 
 University Professor and Professor of Applied Mathematics 
 Research Interests 
Professor Kushner is a fellow of the IEEE,  and  has won   many awards for his work in stochastic systems theory and applications,  including the IEEE 
Field Award in Control Systems and the Franklin Institute Louis E. Levy
medal. 
In 7 books and over 160   papers, he has contributed   to many areas
of stochastic systems theory and applications:  optimization and numerical methods, nonlinear
filtering  theory  and computational approximations,   the  stability 
theory of stochastic systems,  distributed parameter stochastic systems,  
stochastic approximation methods and the theory of  stochastic recursive 
algorithms,   adaptive control theory, the maximum principles and related
variational formulations,    the theory of  large deviations and its
applications  to stochastic systems,  approximation methods for systems
driven by wide bandwidth  noise,   weak convergence methods,    singularly
perturbed  
 systems,  heavy traffic  approximations to controlled queueing  type
problems,  as well as to the applications of  stochastic control techniques
to problems in modern telecommunications systems  and elsewhere. He has
developed  the main current numerical  methods  for   stochastic control
problems in continuous time.
