Biography
About me
I obtained my PhD degrees from Belarusian State University (BSU) and Northern Illinois University (NIU). I
worked in BSU's non-linear physics research group on
solitary wave dynamics in classical field theory, primordial topological defects and NLSE optical systems. I then moved to
Fermi National Laboratory and joined
beam dynamics group
at Northern Illinois
University (NIU). While at NIU, I was involved in variety of Accelerator Physics problems: electron beam phase-space shaping, THz radiation generation and space-charge algorithms.
I am getting constantly energized by the Nature and people surrounding me and I am always searching for new projects and challenges!
