Viacheslav Sadykov is an Assistant Professor at Physics & Astronomy Department of Georgia State University. He obtained his Ph.D. degree from the New Jersey Institute of Technology in 2019, worked as a Research Scientist at BAERI / NASA ARC from 2019 until 2021, and joined the faculty of the Physics & Astronomy Department of Georgia State University in 2021. Viacheslav has wide research interests including development and maintenance of databases of solar flares and flight radiation measurements, prediction of solar transient events using machine learning, machine learning-aided analysis of the spectroscopic observations of the Sun, modeling of solar spectral lines and EUV emission, and analysis of the realistic radiative MHD simulations of the quiet Sun. Viacheslav is one of the main developers of the Interactive Multi-Instrument Database of Solar Flares and the Radiation Data Portal (IMIDSF and RDP, deployed at https://data.nas.nasa.gov/helio/), and a PI and Co-I of several NASA and NSF research grants.
