Biography

During my study at the Irkutsk State University I found my interest in particle and astroparticle physics: participated in development of acoustic detector for neutrino telescope NT-200 at the beginning and later moved to Bogoluibov Laboratory of Theoretical Physics in Joint Institute for Nuclear Reserch (Dubna), where I was working in the field of phenomenology of low-energy hadronic interactions. During my PhD study at Karlsruhe Institute of Technology I have entered the field of radio detection of air-showers at the moment of deployment of second-generation digital radio array Tunka-Rex in 2012, and it was not clear, whether it is feasible to build a radio detector measuring cosmic-ray air-showers with resolution competitive to those of the optical detectors. The results of the first stage of Tunka-Rex had given a positive answer to this question. Later I have developed different methods for the improving the resolution of radio detector and became a principal investigator of Tunka-Rex in 2018. In 2018 I moved to DESY Zeuthen and started work on H.E.S.S., an array of Imaging Atmospheric Cherenkov Telescopes located in Namibia, which consists of four small (12-m mirror) and one large (28-m mirror) telescopes. Within H.E.S.S. I have both technical and scientific responsibilities. I am the leader of the working group responsible for the camera subsystem of small telescopes; additionaly I am working on search for the gamma counterpart to the fast radio bursts; last but not least, I am working on the analysis of possible galactic PeVatrons, a sources featuring high-energy emission which are potentially connected to the cosmic-ray production.
