Vasily N. Astratov is a professor of Physics and Optical Science at the University of North Carolina-Charlotte. In 1986, he received his Ph.D. degree from the A.F. Ioffe Physical-Technical Institute in Russia. In this institute, he had accomplished a career as a research scientist, rising through the ranks from staff member (1981-1992), group leader (1992-1997), to senior member of staff in 1997. In the mid-90s, he pioneered studies of synthetic opals as novel self-assembled photonic crystals for visible light in his group at the Ioffe Institute. In 1997-2001, he was a postdoctoral scholar at the University of Sheffield where he developed novel surface coupling techniques for studying photonic crystal waveguides and semiconductor microcavities. Since joining UNC-Charlotte in 2002, his research was devoted to microspherical photonics including super-resolution microscopy, resonant light forces, photonic nanojets, and photonic molecules. In his group, he developed the methods of super-resolution imaging based on using high-index dielectric microspheres immersed in liquids or in elastomeric slabs. These methods are widely used for imaging subcellular structures, viruses, and nanoplasmonic structures. He was a topical editor for the journal Optics Express in 2005-2011 and a program committee member for major international conferences including CLEO 2006-07 and 2012–15, IEEE Photonics 2014-17, OSA Advanced Photonics Congress 2016-17, Photonics West 2017-18, ICTON 2017-18 and OECC/ACOFT 2008 and 2014. He organized Workshops and Special Sessions on label-free super-resolution at 2017 IEEE Photonics, 2016-17 Physics Quantum Electronics and 2017-18 ICTON conferences. He is a recipient of international visitor awards from LabEx NanoSaclay in Paris (2017), Center of Nanosciences and Nanotechnologies (C2N) in Paris (2016), Center for Material Physics in San Sebastian (2015), Triangle de la Physique in France (2011), EPSRC (2006) and Royal Society (1996) in the UK. He presented 35 invited talks at the international conferences and 60 invited seminars at the major research centers. He authored and co-authored about 180 research publications and 15 patents which were cited more than 5000 times. His Google Scholar h-index is 40.
