Biography
Dr. Yuri Omelchenko is an internationally recognized expert in computational physics. Early in his career, Yuri was advised by Dr. Vitaly Shapiro and Dr. Valentin Shevchenko, who gave a strong initial impetus to his research in ionospheric physics at the Space Research Institute (IKI) of the Russian Academy of Sciences. In 1993 Yuri was invited to work at the Laboratory for Plasma Studies at Cornell University, where in collaboration with Dr. Ravi Sudan and Dr. David Hammer, he pioneered parallel 3D hybrid simulations of Cornell experiments (FIREX) on magnetized plasmas with high-energetic ion beam components. These realistic-scale simulations accurately predicted experimental results and helped establish proper parameters for achieving magnetic field reversal on axis by an energetic ion ring. At General Atomics, Yuri made seminal contributions to the theory of FRCs (Field-Reversed Configurations) and ICRF (Ion Cyclotron Resonance Frequency) wave-driven ion acceleration. Later, Yuri has served as PI, Co-I and Consultant in NASA, NSF, and DOE funded projects. As PI, under NASA and NSF/DOE funding Yuri has developed a novel, AI (artificial intelligence) powered, multiscale hybrid code, HYPERS for massively parallel simulations of large-scale space and laboratory plasmas. HYPERS is the only PIC (Particle-in-Cell) code that performs asynchronous advance of particles and electromagnetic fields on their local physical scales. This revolutionary computational technology (EMAPS = Event-driven Multi-Agent Planning System) has been proven to achieve superior accuracy and performance in simulations of the Earth’s magnetosphere, laboratory plasmas, and shock-driven particle acceleration. In 2021 the HYPERS-Global model (https://ccmc.gsfc.nasa.gov/models/HYPERS-Global~2021) became the first hybrid model available for public use at the NASA CCMC. In 2014 Yuri joined the Space Science Institute (Boulder, CO). In the same year Yuri founded Trinum Research, Inc. (San Diego, CA), where he initiated his long-standing collaboration with the Ohio State University. This on-going work has resulted in three Ph.D. theses and produced novel computational tools for full electromagnetic modeling of electronic devices, particle accelerators and space plasmas. Yuri performed unique 3D hybrid simulations of ion ring excited lower hybrid turbulence for space missions. Serving as PI in NASA funded projects, Yuri has used HYPERS to carry out some of the largest global 3D hybrid simulations of the Earth’s magnetosphere on NASA supercomputers. These simulations have helped interpret the physical origin of high-speed jets (HSJs) and their impact on the magnetosphere. Since 2018 Yuri has been serving as an adjunct faculty member at the Physics and Engineering Department at Palomar College, where he teaches introductory and advanced physics courses to undergraduate students who plan to major in engineering and life sciences.
