Leonid V. Tanin is Academician of the International Academy of Engineering, doctor of physical and mathematical sciences, honored Inventor of the Republic of Belarus, Chairman of the Board of Directors of CJSC HOLOGRAPHY INDUSTRY.

In 1971 he graduated from Physical Department of State Leningrad University (Department of Optics and Spectroscopy), in 1974 - postgraduate course of Leningrad Physical and Technical Institute of A.F. Ioffe of the Academy of Sciences of the USSR (Sector of Plasma Optics). In 1978 he created a scientific group "Coherent-optical studies of medical and biological systems" in the Research Institute of Neurology, Neurosurgery and Physiotherapy of the Ministry of Health of the BSSR and he was in charge of it more than 20 years. Leonid Tanin is one of the founders of a future-oriented field in science - biomedical optics. He developed the basis of speckle-optical diagnostics and laser hemotherapy in the treatment of diseases of peripheral and central nervous systems, he created the diagnostic device "Laser specklometer", that does not have analogs in the whole world, for the study of biomechanical activity of muscles and surface blood flow. In 2012 for the monograph "Biomedical and resonant optics: theory and practice" Leonid Tanin and Andrei Tanin were awarded the First Prize named after Yu.I. Ostrovsky "For the best scientific work in the field of optical holography and interferometry" of the Russian Academy of Sciences. In 2014 Leonid Tanin successfully defended his doctoral thesis on the topic "Resonant holographic and speckle-optical studies of phase, diffuse and mirror objects".

Leonid Tanin is the author of 300 scientific publications, including 4 monographs, 78 patents and certificates of authorship and patents that are registered both in our country and abroad, coauthor of two teaching textbooks.

He was a member of the International Program Committees in the field of biomedical optics (1990, 1992, Germany; 1994, Japan; 2002, Belarus). He presented lecture courses in this sphere in the leading universities and world scientific centers.

In 1994 Leonid Tanin was elected Chairman of the Belarusian Society of Biomedical Optics in the Belarusian branch of SPIE (USA).

Andrei L. Tanin is Associate Professor, from 2010-2015 a director of State Establishment "Republican Scientific and Practical Center of Neurology and Neurosurgery" of the Ministry of Health of the Republic of Belarus, a chief neurosurgeon of the Ministry of Health of the Republic of Belarus.

After graduating from Minsk State Medical Institute Andrei Tanin began studying at clinical residency and afterwards he entered postgraduate studies in the neurosurgical department of the Research Institution of Neurology, Neurosurgery and Physiotherapy of the Ministry of Health of the Republic of Belarus. In 2003 he successfully defended candidate dissertation "Restoration of the function of peripheral nerves after neuroraphy under the influence of laser hemotherapy".

Andrei L. Tanin is one of those who developed a completely new in modern medicine speckle-optical diagnostics and laser hemotherapy in treatment of peripheral and central nervous systems. With his participation the monograph "Laser hemotherapy in the treatment of diseases of peripheral nervous system" was published.

Since 2015 he has been the associate professor of the department of neurology and neurosurgery of State Educational Establishment "Belarusian Medical Academy of Postgraduate Education", a leading researcher at the State Establishment "Republican Scientific and Practical Center of Neurology and Neurosurgery." He was awarded the badge "Excellence in Health Care of the Republic of Belarus", diplomas of the Ministry of Health of the Republic of Belarus and the National Academy of Sciences of Belarus.

His main research interests are related to the problems of surgical treatment of intracerebral hypertensive hemorrhages, supratentorial gliomas and damage to peripheral nerves.
