Sergey Nechayev

I had an opportunity to work in the structured quantum optics (SQO) group of Prof. Ebrahim Karimi at the University of Ottawa (uOttawa). The SQO group is an extremely productive team of young and motivated scientists from all around the world. The SQO team is internationally known for its ingenious research and for their groundbreaking experiments in quantum optics with photons that have spatially inhomogeneous polarization and wavefront distributions. The SQO group is strongly driven by scientific curiosity and they conduct their experiments on Earth (in their top-tier equipped labs), in Space and underwater!

The research environment and interpersonal dynamics are very unique in Ebrahim’s group. Ebrahim always puts the needs of his group members on top of his priority list. He is available to his group 24/7, he is always ready to help with anything (including personal matters) and he is very supportive in terms of career development. Needless to say, Ebrahim is a great and a very creative physicist who is always ready to engage in a scientific discussion about anything, even the most crazy ideas. Overall, working in the SQO group at uOttawa under Prof. Ebrahim Karimi supervision was a very exciting experience.

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.
