Andrey A. Gelash is a Full Professor of Physics at the Center for Engineering Physics, Skolkovo Institute of Science and Technology, Moscow, Russia. At Skoltech, he leads the RSF Megagrant project "Nonlinear effects in macroscopic wave systems and photonic integrated devices" and a theoretical group on nonlinear physics. Prof. Andrey Gelash received BS and MS degrees in Physics from Novosibirsk State University. Afterward, he defended a PhD Thesis in Theoretical Physics at L.D. Landau Institute for Theoretical Physics, Moscow. Later, he worked at different research positions at the Laboratory of Nonlinear Wave Processes, Novosibirsk State University, Kutateladze Institute of Thermophysics SB RAS, Institute of Automation and Electrometry SB RAS, and Center for Advanced Studies at Skoltech. He was also a lecturer at Novosibirsk State University and invited lecturer at the University of Lille, France. After he was awarded a Marie Skłodowska-Curie fellowship, he spent two years at the Laboratoire Interdisciplinaire Carnot de Bourgogne, CNRS-Université Bourgogne Franche-Comté, Dijon, France. Then he carried out research at the Laboratory of Photonic Integrated Circuits and Quantum Measurements, École polytechnique fédérale de Lausanne (EPFL).

At Skoltech, Prof. Andrey Gelash and his team predict new coherent states of light in optical microresonators, calculate the probability of the emergence of extreme-amplitude waves, and develop a theory of integrable turbulence and a universal algorithms for the nonlinear Fourier transform. One of the recently emerged directions of study is dedicated to the applications of physics-informed neural networks in nonlinear physics. In collaboration with the experimental team at the Center for Engineering Physics of Skoltech, Prof. Andrey Gelash and his team are working on nonlinear, coupled microresonator devices to generate optical frequency combs.
