Sergey Nechayev received his bachelor degrees in Physics (2007) and Mathematics (2009) from Technion – Israel Institute of Technology. He became interested in optics and continued to the M.Sc (2012) program at Technion, specializing in plasmonics and singular optics. During his Ph.D. degree (2016), Sergey led a project that aimed at developing efficient incoherent pumping methods for solar powered lasers and renewable energy applications. He took on his first postdoctoral appointment at the Max Planck Institute for the Science of Light in Germany to conduct research on structured light, nano-optics, nano-photonics and light-matter interactions. He used nano-optics as a platform to experimentally investigate fundamental electromagnetic conservation laws at the nanoscale.

Sergey joined the SQO group in June 2019 as a Postdoctoral Fellow, where he works with Prof. Karimi on studying interactions between light, matter and quantum matter waves in extreme ultrafast, nonlinear and quantum regimes.
