Sergei graduated, had his PhD and started his research in Nonlinear Optics lab at the Moscow State University. From 1992 to 1996 he continued his research in nonlinear optics of solids in Southampton University, and since 1997 joined the Femtosecond Optics Group. He held an EPSRC Advanced Research Fellowship from 2000 to 2005 in fibre based visible laser sources, the Royal Society Industry Fellowship from 2006 to 2010 in fibre lasers for medical applications in collaboration with IPG Photonics, the world’s largest fibre laser company. Within this fellowship framework, he initiated, organized and chaired a number of international conferences on high power lasers and their applications.  He published two academic books, over 80 journal papers and has over 100 co-authored conference presentations. Sergei's research focuses on the development of a family of compact and efficient, high-power, fibre-based lasers that are designed to operate over broad wavelength ranges. This has led to new product lines that have had recognizable impact on the commercial laser market place including major fibre lasers manufacturers. The basic research on these unique lasers was initially undertaken by Sergei and the Femtosecond Optics Group team at Imperial College. The development, power scaling and application of these sources were carried out  primarily in collaboration with IPG Photonics. Devices operating in several discrete wavelength ranges have been particularly commercially successful in the scientific laser market place and have also been applied in various clinical trials and treatments. Sergei maintains strong industrial collaborative links of the Femtosecond Optics Group including research projects with IPG Photonics USA, NTO IRE Polus and General Physics institute in Russia.
