"Gaining more by settling for less: disentangling the global oceanic circulation and flows in high-energy-density plasmas"


Flows in nature and in engineering are often complex, forced by external agents, boundary stresses, and internal instabilities, and pervaded by multiscale structures such as eddies, plumes, jets, waves, and turbulence ---spanning many orders of magnitude in size. The nonlinear nature of the dynamics implies a coupling between these multiple scales, which often plays a major role in determining mean-flow evolution and is a primary factor limiting our predictive modeling capabilities. To tackle this wide class of problems, I will present a scale-analysis framework we have been developing that is rooted in commonly used techniques in the subjects of PDEs, Renormalization Group, and Large Eddy Simulation modeling. Guided by rigorous mathematics and physical insight, we use this methodology to probe data from massively parallel simulations, satellite observations, and experimental measurements. I will discuss applications and recent results from high-energy-density plasma flows and the global oceanic circulation.


Hussein is an Associate Professor in the Hajim School of Engineering at the University of Rochester (UofR) and Staff Scientist at the DOE Laboratory for Laser Energetics. He currently serving as chair-elect of the Group on the Physics of Climate (GPC) within the American Physical Society (APS). He held a postdoctoral appointment at the Center for Nonlinear Studies at Los Alamos National Laboratory, earned his PhD from Johns Hopkins University, and his BSc from the American University of Beirut. His research has been supported by NSF, DOE, NNSA, and NASA, and was awarded the DOE Early CAREER Award in 2019. In 2022, he was selected as one of two Young Observers by USNCTAM, which represents the mechanics community on behalf of the US National Academies. His Complex Flow group is diverse both in the composition of its members and in its research, which has appeared in cross-disciplinary journals, including Nature, Science Advances, Physical Review Letters, as well as in disciplinary journals of fluid mechanics, oceanography, plasma physics, applied mathematics, and astrophysics. Hussein was born in Beirut, Lebanon and enjoys outdoor sports, live music, and swing dancing.
