My current research is focussed on problems at the interface of physics and control. A fundamental problem in coherent spectroscopy and quantum information science is to find limits on how close can an open quantum dynamical system be driven to a target state in the presence of dissipation and decoherence and what is the optimal excitation that achieves this objective. We are studying these problems in the context of design of multidimensional NMR experiments that maximize the efficiency of transfer of coherence between coupled spins in the presence of decoherence and optimize the sensitivity of these experiments. Other projects include development of novel radio frequency pulse sequences for time optimal control of coupled spin systems with applications in spectroscopy and quantum informaion processing. Problems in robust control of spin systems, that are immune to parametric inhomogeneties in system dynamics. In recent years, we have also worked in development of new methods in high resolution nuclear magnetic resonance spectroscopy in solution and solids. The work has an important collaborative experimental component. Some past projects involve feedback stabilization of nonholonomic systems and problems in machine intelligence and statistical inference.
