In 2008, graduated from the National Mining University, received a full higher education in the specialty "Mineral processing", specialization "Mineral raw material beneficiation technologies" and obtained the qualification "Mining process engineer with a research level of activity, teacher of a higher educational institution"

From 2017 to 2019, studied at a graduate school, majoring in 05.15.08 – Mineral processing.

Candidate of Technical Sciences, specialty 05.15.08 – Mineral processing, from 2020; thesis topic: "IMPROVEMENT OF THE TECHNOLOGY OF THE ENRICHMENT OF RAW MATERIALS OF HETEROGENEOUS LIMESTONE DEPOSITS"

Since April 2017, worked as a senior laboratory assistant at the department of technological engineering of materials processing.

Associate Professor of the Department of technological engineering of materials processing since 2020.

From September 2021 to August 2022, served as the head of the Department of Materials Processing Technological Engineering.

Takes an active part in the research work of the department on foam flotation of non-oxidized iron ores, rare earth and precious metals; screening of wet and sticky mineral raw materials; classification of finely dispersed materials; crushing and grinding of non-ore and ore mineral complexes of man-made origin.

Scientific interests currently cover the process of deep beneficiation of non-oxidized ferruginous quartzites by methods of HGMS and foam flotation (increased extraction of hematite) and classification of non-ore materials (wet fine screening).

Since 2021 - Director of the Center for processing and beneficiation of mineral and man-made raw materials of the Dnipro University of Technology.

As part of the reorganization of the educational process in the specialty 184 Mining, from September 2022 was transferred to the position of associate professor of the department of ecology and environmental protection technologies.

Conducts practical and laboratory work in the disciplines: "Preparatory processes of mineral enrichment"; "Technologies of beneficiation of ferrous metal ores and coal"; "Enrichment of minerals"; "Theoretical foundations of materials processing".
