Robert Lysak

Robert Lysak is a Professor in the School of Physics and Astronomy at the University of Minnesota, specializing in theoretical plasma physics with focus on magnetospheric and auroral phenomena. His research spans Earth's magnetosphere, planetary systems including Jupiter, solar wind dynamics, and astrophysical plasmas.

His primary research interests include:

• Plasma dynamics in Earth's auroral regions and magnetosphere
• Kinetic Alfvén wave theory and particle acceleration mechanisms
• Ultra-low-frequency (ULF) wave eigenmodes and propagation
• Magnetic reconnection processes in thin current sheets
• Comparative studies of Earth and Jupiter's magnetospheric physics
• Solar corona phenomena including heating and eruptions

Recent publications (2023-2024) demonstrate continued focus on comparative Alfvén wave analysis between Earth and Jupiter, Io-generated wave interactions in Jovian magnetosphere, low-latitude Pi2 pulsation mechanisms, and double-layer electric discharge models for auroral substorms. His work consistently integrates kinetic theory with numerical modeling to explain fundamental plasma processes.

As Principal Investigator, Dr. Lysak manages 17 research projects including:

• Numerical Modeling of ULF Waves and Geomagnetically Induced Currents (NSF, 2022-2025)
• Magnetosphere-Ionosphere Coupling and Auroral Acceleration at Earth/Jupiter (NASA, 2020-2025)
• Global Propagation of Pi2 Waves (NSF/Johns Hopkins, 2019-2024)
• Kinetic Field Line Resonances Modeling (NASA, 2019-2022)

He maintains active collaboration with Senior Researcher Dr. Yan Song on particle acceleration theory and magnetic reconnection dynamics, with joint projects including NSF-funded ULF wave modeling. His research group utilizes advanced numerical techniques and contributes to understanding space weather phenomena relevant to planetary science and solar-terrestrial interactions.
