Brief Bio

Roman Samulyak holds a joint appointment at the AMS Department, Stony Brook University and Computational Science Center, Brookhaven National Laboratory. He joined the Brookhaven Laboratory after graduation, and worked there for 8 years. R. Samulyak conducted research in mathematical modeling, numerical algorithms and the simulations of complex physics processes in particle accelerators, and energy research applications. He served as the principal investigator for several Department of Energy (DOE) funded projects. He performed numerical studies of liquid mercury targets for future particle accelerators such as the Neutrino Factory / Muon Collider and the Spallation Neutron Source, collective interactions of particles in accelerators, and the fueling of thermonuclear fusion devices by the injection of cryogenic pellets. He developed new models and numerical algorithms for multiphase hydro and magneto-hydrodynamic flows with phase transitions, electromagnetic systems etc. After joining Stony Brook University in 2007, R. Samulyak continues research in the area of numerical algorithms and large scale simulations of complex systems.
