Research interests

Scientific research is carried out within the personal initiative on the topic: “Analysis of data by machine learning” рDr 0119U002409 and the state budget topic SN-59F “Obtaining and research of nanosystems based on chalcogenide semiconductors with natural nanostructured matrices” (free time from work). Processing of raw three-dimensional experimental data and converting them into two-dimensional format for analysis by machine learning and development of algorithms for analysis of large arrays of spectral data obtained for solid surfaces by scanning tunneling spectroscopy and slow electron diffraction using Python. The aim of the work is to optimize data processing in the process of transition from their receipt to analysis and algorithmization of experimental data processing, software design and development in order to obtain reliable conclusions about experimental data.

Processing and analysis of data obtained for solid surfaces by scanning tunneling spectroscopy is an urgent problem, given the size of the corresponding experimentally obtained data sets, and a number of parameters used by their researchers of data interpretation. The aim of the work is to optimize the conversion of data formats in the process of transition from data acquisition to their processing and algorithmization of experimental data processing, software design and development in order to obtain conclusions about experimental data.
