NSLS-II Accelerator Physics Group leader since 2015. Our main duty is to provide efficient scientific support for NSLS-II operations and work on improvements and developments including optimization of the NSLS-II performance with high beam current and low emittance, improvement of the beam stability, development of new software tools for operations and beam studies. At the same time, we are productively working on advanced studies of topical scientific problems.
