Rate My Professor Roman Grigoriev

Roman Grigoriev is a Professor in the School of Physics at the Georgia Institute of Technology. He received his Ph.D. in Physics from the California Institute of Technology in 1998 and his M.S. from Moscow State University in 1992. Grigoriev leads the Dynamics and Control Group at the Center for Nonlinear Science. His research centers on dynamical systems, fluid dynamics, excitable systems, machine learning, and control. He explores emergent behaviors in active matter systems at molecular scales, turbulence dynamics, and data-driven discovery of physical models from experimental data.

Grigoriev's contributions include developing new dynamical frameworks for turbulence, demonstrating that turbulence tracks recurrent solutions and exact coherent structures, as detailed in publications such as "Turbulence tracks recurrent solutions" (Proceedings of the National Academy of Sciences, 2022), "Exact coherent structures and shadowing in turbulent Taylor-Couette flow" (Journal of Fluid Mechanics, 2021), and "Capturing turbulent dynamics and statistics in experiments with unstable periodic orbits" (Physical Review Letters, 2020). In machine learning applications to physics, key works encompass "Physically-informed data-driven modeling of active nematics" (Science Advances, 2023), "Robust learning from noisy, incomplete, high-dimensional experimental data via physically constrained symbolic regression" (Nature Communications, 2021), and "Learning fluid physics from highly turbulent data using sparse physics-informed discovery of empirical relations (SPIDER)" (Journal of Fluid Mechanics, 2024). His research, cited over 2,700 times, has advanced predictions of turbulence wiles and resolved mysteries of microtubule movers through active matter models. Grigoriev earned the François Frenkiel Award for Fluid Mechanics in 2010 and the Georgia Tech Sigma Xi Best Faculty Paper Award in 2022.
