Research interests: Phytocoenology (phytocoenotic structure of forest communities: methods of study, geographical and ectopic patterns, theoretical and applied aspects, classification of coenoelements); forest science (forest-forming process, natural and anthropogenic dynamics of forest ecosystems, ground-based environmental monitoring, stationary studies, problems of Far East forestry); biology, ecology and biomorphology of forest plants; consortium ties (influence of wild animals on vegetation, conservation of habitats of Red Book animals); problems of forest biodiversity (natural restoration of vegetation in areas disturbed by fires and mining operations; invasions of tree and shrub species); primary forest productivity; rational environmental management.
I graduated from the forestry faculty of the Primorsky Agricultural Institute with a degree of engineer forestry. The total experience in scientific organizations is 51 years, including 11 years at the Magadan Forest Experimental Station (FES) of Far Eastern Forestry Institute, the rest of the time in the system of the Far East Branch of the Russian Academy of Sciences: the Institute of Biological Problems of the North (IBPN), the Mountain Taiga Station (MTS) and the Botanical Garden-Institute (BGI). At the Magadan FES, I was engaged in researching the consequences of forest fires, the biological forest stability at the northern limit of growth and the forests primary productivity, at the IBPN I studied the primary productivity and phytocoenotic structure of the forests, restoring the plant cover in disturbed areas. Since 1992, in Primorsky Territory, I have continued researches by the phytocoenotic structure of derived forests of Southern Primorye, including anthropogenic seabuckthorn communities. Supervised research on the ecological profiles "Snow Valley" (Northern Okhotsky Sea-coast) and "Mountain-taiga" (Southern Primorye), created in the main types of derived forests to study the reforestation process and ground monitoring. In 1984, I defended dissertation by the specialty 03.00.05 - botany at the degree of candidate of biological sciences, in 2005 – at the degree of doctor of biological sciences. From 2005 to 2012, I taught part-time as a professor at the School of Pedagogy of the Far Eastern Federal University (FEFU) in Ussuriysk; over the years, opposed candidate and doctoral dissertations, was the executive editor of collections of scientific papers and monographs, and supervised undergraduate and graduate students.

For more than 10 years, I have been acting as chairman of the State Attestation Commissions in the specialty "Ecology" in the School of Pedagogy of the Far Eastern Federal University and (or) in the specialty "Forestry" in the direction "Forest science, forestry, forest management and forest inventory" in the Institute of Forestry and Forest-Park Management of the Primorsky State Agricultural Academy. I participate in the work of scientific and practical conferences of various levels in Russia and abroad. I am a member of the editorial board of the Siberian Forestry Magazine , a reviewer of the magazines "Forest Science" and " Messenger NESC FEB RAS" and the electronic magazine "Bulletin of the BGI FEB RAS"; recommended as a candidate member of the Expert Council of the Russian Academy of Sciences by natural sciences from the Far East Branch of the Russian Academy of Sciences. During the work, 133 works have been published, including four monographs, and three electronic lecture courses of academic disciplines for environmental universities: biogeocenology, general ecology and flora of the Far East (short course).
