Sergey Ivanov is a physicist working at the intersection of nonlinear optics, topological photonics, and nonlinear wave dynamics. He received his PhD from ISAN/MIPT, where he studied fundamental nonlinear wave phenomena including solitons and dispersive shock waves. He has held postdoctoral positions at ICFO (Barcelona) and the University of Valencia, focusing on nonlinear and topological states of light in photonic lattices. His work combines theory and computation to explore how topology and nonlinearity shape wave propagation in structured media, with 40+ publications in leading journals.
