Professional interests/researches
Main academic interests relate to research in the field of laser medicine and biomedical optics, speckle optics, medical electronics equipment and new biomedical technologies. He developed an experimental prototype device Speckle-SCAN and new non-invasive speckle-optical methods, allowing to obtain information about the functioning of microcirculatory bloodstream in clinical setting and to ensure non-invasive monitoring of the effectiveness of photodynamic treatment during photodynamic therapy of tumors and a number of other non-oncological diseases, including in dentistry.
