The basic scientific direction of professor Oleg Mayorov is the development of diagnostic technologies in neuro- and cardio-diagnostics, intellectual training systems, and information-processing in health care. He is the author of the computerized qEEG system NeuroResearcher®Innovation Suite & qHRV - Cardio-Tension-Test® (V21.5, 1984 - 2025) encompassing EEG and HRV programs (qEEG & qHRV), a new method of research multivariate linear neurodynamic systems of the brain and functional asymmetry of hemispheres. He has created the newest technology of research of nonlinear dynamics in the brain on EEG (deterministic chaos); technologies of objective estimation of functional systems in an organism with the aim of assessing the efficiency of medical treatment in schizophrenia, Alzheimer’s disease, depression and a diabetes.

Under his management, a fully-functional hospital information system using high-performance object databases, using a post-relational database, an electronic signature, the protection of personal data, has been created. Prof. Oleg Mayorov is the co-author of the Concepts of a State policy of the Public health information of Ukraine (1995, 2013), the State Public Health Program (2006-2010), Scientific director of the National Program and Action Plan for 2014-2016 years and the architecture of the National network UkrMedNet. He is author and project manager of the sanitary and epidemiologic monitoring system in the large industrial city “SEMON“.

UACM in 2004 have begun to edition the journal “Clinical Informatics and Telemedicine” (ISSN 1812-7231(print), ISSN 2786-5800 (on-line) (https://kit-journal.com.ua/en/index_en.html). Prof. Oleg Mayorov is Editor-in-Chief.
