Alexander Osadchiev graduated from Faculty of Mechanics and Mathematics at Lomonosov Moscow State University in 2009. Since 2009, he is working at Shirshov Institute of Oceanology, Russian Academy of Sciences. In 2013, he defended PhD thesis titled "Dynamics of spreading and variability of river plumes in the Coastal Zone." In 2021, he defended Habilitation thesis titled "Structure, dynamics, and variability of river plumes."

Research interests include physical oceanography of coastal and shelf seas, river plumes and estuarine processes, anthropogenic impacts on marine systems.

Main research areas:

1. Structure and circulation of major water masses (freshened surface waters, Atlantic and Pacific waters, cold dense waters) in the Eurasian Arctic seas.
2. Propagation and transformation of river runoff in the sea, impact of these processes on the hydrological structure and dynamics in coastal and shelf areas.
3. Development of applied numerical models: forecasting the timing of sea ice formation and melting in the Arctic Ocean, assessment of strength characteristics of sea ice cover in the Arctic Ocean, the propagation of riverine pollutants in the sea.

Alexander Osadchiev published more than 100 scientific papers and the monograph "River Plumes" (in Russian). His h-index (Scopus) is 24, number of citations (Scopus) is ~1500. Alexander Osadchiev participated as PI in grants received from the Russian Science Foundation, the Russian Foundation for Basic Research, the Ministry of Education and Science of Russia, and international projects. He organized and participated in more than 40 oceanographic research cruises in the Arctic, Pacific, and Atlantic oceans. He is the Scientific Director of the program "Floating University of the Institute of Oceanology of the Russian Academy of Sciences - Moscow Institute of Physics and Technology".

In 2023, Alexander Osadchiev opened and headed the Arctic Oceanology Laboratory at Moscow Institute of Physics and Technology. He supervised two dozen undergraduate and master's theses for students from MIPT, Lomonosov Moscow State University, and Russian State Hydrometeorological University. He supervised one defended PhD dissertation, and four more are in preparation for defense.

Member of the Expert Group on Capacity Development of the Intergovernmental Oceanographic Commission of UNESCO. Member of the section "International Scientific Cooperation in Marine Activities and Ocean Development" of the Scientific Expert Council of the Marine Collegium of the Russian Federation. Member of the Working Group of the Floating University scientific and educational program of the Interdepartmental National Oceanographic Commission of the Russian Federation.

He is actively involved in popularizing science, the author of the popular science book "This Unknown Ocean," and runs the popular science Telegram channel "The Ocean Around Us."

Awards:

1. The Russian Presidential Award in Science and Innovation for Young Scientists (2022) is awarded for achievements in the study of oceanographic processes in the seas of the Russian Arctic, which are of great importance for economic activity in the waters of the Northern Sea Route.
2. Moscow Government Award for Young Scientists (2020) – for a series of works devoted to the study of the distribution and transformation of river runoff in the coastal and shelf zones of Russian seas.
3. Medal of the Russian Academy of Sciences with a prize for young scientists for the best scientific work (2018) - for a series of works devoted to the study of the influence of continental runoff on hydrophysical processes and water quality in the coastal zone of the sea.
