Congratulations to G. A. Ososkov on his 95th birthday! On 13 February 2026, Gennady Alekseevich Ososkov, Doctor of Physical and Mathematical Sciences, Professor, Chief Researcher of the Scientific Department of Computational Physics of the Meshcheryakov Laboratory of Information Technologies of the Joint Institute for Nuclear Research, celebrates his 95th birthday. G.A. Ososkov has been working at JINR since 1961. He headed the successful development of mathematical software for automated measuring systems of experimental data at JINR. Under the guidance and with the participation of Prof. G.A. Ososkov, new fast and highly efficient methods for detecting event tracks and vertices, Cherenkov radiation rings, and electron shower centers were created and implemented on the basis of the widespread use of robust statistical methods, cellular automata, and neural networks. These results found wide application in many large-scale physical centers of the world (CERN, DESY, BNL). Scientific interests of G.A. Ososkov encompass problems of simulating physical processes in experimental high- and low-energy physics and the statistical analysis of experimental data. One of the confirmations of the generality and effectiveness of the developed methods was their successful application in medicine and ionospheric research. G.A. Ososkov made a considerable contribution to the work carried out by JINR in the СВМ experiments (GSI, Darmstadt). Recently, G.A. Ososkov has focused on issues related to the NICA project. Machine learning methods are employed to solve various types of tasks for the BM@N, MPD, and SPD experiments, namely, tracking, field map reconstruction, search for interaction vertices, and particle track clustering by events in time slices. Under his guidance, work on the dynamical simulation of processes involved in storing, transferring, and analyzing data for the computer infrastructure of the project is underway; the SyMSim program for modeling a grid-cloud environment has been developed. A new system for modeling grid and cloud services, integrating the monitoring, analysis of results, and modeling itself, has been created within the project. From 2014 to 2017, Gennady Alekseevich was the head of two RFBR scientific grants. G.A. Ososkov is a prominent scientist in the field of applications of probability theory, computational statistics and pattern recognition, as well as in the processing of data from physics experiments. He has published over 300 scientific papers, including two monographs, articles in prestigious domestic and foreign journals and texts of reports in proceedings of international conferences. G.A. Ososkov pays constant attention to work with young specialists. He is a professor of Dubna University and from 2000 to 2015 was a professor at the Department of Information Technologies of the Dubna branch of MIREA. Gennady Alekseevich is a member of the MLIT Science and Technology Council and the MLIT Dissertation Council. He is the author of four textbooks. Under the supervision of G.A. Ososkov, 12 of his students defended their Ph.D. theses, and over 30 graduates defended their diplomas, master’s and bachelor’s theses. Gennady Alekseevich holds the title of Honorary Doctor of the Mongolian State University in Ulaanbaatar and was awarded the medal “In Commemoration of the 850th Anniversary of Moscow”, the departmental badge of distinction in labor “Veteran of Nuclear Energy and Industry”, the Silver and Gold medals of the Slovak Academy of Sciences, the anniversary medal in honor of the 70th anniversary of the Mongolian State University. He has the title of “Honorary Fellow of JINR” and was awarded JINR’s Certificate of Honor and JINR’s Honorary Diploma for the services to JINR. Gennady Alekseevich also has the diploma of Honorary Professor of Dubna University and the title of Honored Scientist of the Moscow Region. In 2021, he was awarded the Certificate of Honor of the Ministry of Science and Higher Education of the Russian Federation. Gennady Alekseevich is known not only for his academic achievements and mentorship, but also for his love of sports (he regularly swims and nordic walks), but also for his talent as a poet. Our hero of the day dedicated one of his poems to his birthday: On behalf of the Institute’s Directorate and the Directorate of the Meshcheryakov Laboratory of Information Technologies, colleagues, and friends, we heartily congratulate Gennady Alekseevich on his anniversary and wish him the best of health, happiness, positive thinking, inspiration and energy, new achievements in science and creative work!
