Alexey Frolov

Assistant Professor
Center for Computational and Data-Intensive Science and Engineering

Dr. Alexey Frolov obtained his Specialist Diploma in Computer Science from the Bauman Moscow State Technical University (BMSTU) in 2010, and his Candidate of Sciences degree in Mathematics from the Institute for Information Transmission Problems of the Russian Academy of Sciences (IITP RAS) in 2012. During the following four years, Alexey did research internship at the Ulm University (Germany), Swiss Federal Institute of Technology (EPFL, Switzerland), University of Maryland (USA) and Israel Institute of Technology (Technion, Israel) which resulted in joint publications in leading journals on information and coding theory. Alexey has been a Senior Researcher at IITP RAS since 2013. In 2015-2016, Alexey was a project leader of a joint project of Huawei and IITP RAS on investigation and development of error-correcting codes for future 5G physical layer. Since 2016 he has been a Senior Research Scientist at Skolkovo Institute of Science and Technology (Skoltech). Alexey has developed and teaches a novel course «Information and coding theory» at Skoltech. He is a recipient of Russian Government Award in Science and Technology for Young Scientists (2016), Moscow Government Award for Young Scientists (2013) and Russian President Scholarship (2013). Since 2017 Alexey has been an Assistant Professor at Skoltech.
