Career

  • 1994 - present – way from Junior Researcher to Leading Researcher, Research Institute for Physical Chemical Problems of Belarusian State University;
  • 1996 - 1997 – Postdoctoral Researcher, Max Planck Institute for Radiation chemistry (now Max Planck Institute for bioinorganic chemistry), Muelheim/Ruhr, Germany;
  • 2002-2009 – Visiting Scientist, Institute for Medical Physics and Biophysics, University of Leipzig, Germany (Prof. J. Arnhold, Prof. D. Huster groups).

Current research activity

  • free-radical chemistry of biological important molecules, especially lipids and their simulate compounds;
  • search for regulators of free radical fragmentation of lipids among natural substances, studying the effect of this process on the structure / properties of the bilayer membrane and lipid-protein interactions.

Main achievements

  • 1990 - 2010  –  new fundamental knowledge obtained in the field of lipid chemistry. A previously unknown free radical process was discovered with the participation of glycero- and sphingolipids - a fragmentation reaction that occurs in the polar part of lipids when they interact with reactive oxygen species. It was revealed that free radical reactions can occur not only in the lipophilic (peroxidation), but also in the hydrophilic part (fragmentation) of the lipid membrane; the relationship between these processes has been determined;
  • 1996 - 2009  – numerous Grands of German Academic Exchange Service and German Research Council;
  • 2001 - 2004  – participant in the project of International Science and Technology Center (№ В 434);
  • 2011  –  the diploma of the winner of competition on the best doctoral dissertation of year awarded by Higher certifying commission of Belarus;
  • 2006 - present – leader of numerous research projects funded by BSU, Belarusian Republican Foundation for Fundamental Research, the Ministry of Education of Republic of Belarus.

Developments

  • various methods have been developed to study the radical-regulatory properties of biologically active compounds, based, inter alia, on the method of fluorescent probes;
  • more than 100 research papers have been published, as well as two textbooks (Yurkova I.L. Bioanalytics - Minsk: BSU, 2017. – 359 p.; Yurkova I.L. Nanobioanalytics - Minsk: BSU, 2019. – 195 p.)
