Moldovan scientists – among the most respected scientists in the world

Stanford University in the USA annually compiles a list of “2% of the most respected scientists in the world” (World’s Top 2% Scientists). The list for 2022 includes four scientists from Moldova — Doctor Habilitatus in Physical and Mathematical Sciences Ghenadii Korotcenkov, Doctor Habilitatus of Technical Sciences Oleg Lupan, Doctor Habilitatus of Technical Sciences Valentin Oleshchuk, and Doctor Habilitatus of Physical Sciences Denis Nika.

The top 2% of scientists in the world in their fields by citations, according to the ranking of Stanford University professor John Ioannidis, is compiled on the basis of an updated international database of scientific publications and their citation level. Currently, the total number of scientists worldwide with at least five publications registered in the international database exceeds 9 million people.

Moldovan scientists entered the top in the following disciplines:

• Doctor of Science in Physics and Mathematics, Professor of the State University of Moldova Ghenadii Korotcenkov, Laureate of the Prize of the Academy of Sciences of Moldova in 2019, Laureate of the National Prize of Moldova in 2022 – is among the Top 2% of scientists in the sections Applied Physics / Analytical Chemistry in the cluster of Physics and Astronomy;

• Doctor of Science in Engineering, Professor of the Technical University of Moldova Oleg Lupan, Laureate of the National Prize of Moldova in 2018 – is among the Top 2% of scientists in the Applied Physics/Nanotechnology sections in the Physics and Astronomy cluster;
• Doctor of Science in Engineering, Chief Researcher at the Institute of Energy (affiliated in 2022 with the Technical University of Moldova) Valentin Oleshchuk, Laureate of the Academy of Sciences of Moldova 2021 – is among the Top 2% of scientists in the sections Electrical Engineering and Electronics/Energy in the Engineering Sciences cluster ;
• Doctor of Physical Sciences, Professor of the State University of Moldova Denis Nika, Laureate of the Prizes of the Academy of Sciences of Moldova for young scientists in 2010 and 2013, Laureate of the Prize of the Academy of Sciences of Moldova in 2016 in the field of physics – is among the Top 2% of scientists in the sections Applied Physics/Nanotechnologies in the Physics and Astronomy cluster.

Each researcher has made a significant contribution both to the development of his field of knowledge and to the promotion of the image of the Republic of Moldova beyond its borders, including through broad international cooperation in the field of international scientific and technical cooperation.

Ghenadii Korotcenkov

In particular, Professor G. Korotchenkov, a world-class specialist in the field of materials science, gas sensors, and thermoelectricity, has experience in successful cooperation with colleagues from the USA, Spain, and the Czech Republic. It should be especially noted the long-term work of G. Korotchenkov for more than 11 years as a visiting researcher at two well-known universities in South Korea, performing (on a modern element base) research and development of a new generation of gas sensors and detectors for monitoring the environment. G. Korotchenkov is the author of more than 600 publications (which include more than 30 review publications and more than 40 chapters in generalizing monographic works), continuing to cooperate as an executive editor in a number of prestigious foreign publications in this field.

Oleg Lupan

Professor O. Lupan is a world-class expert in the field of solid-state physics, microelectronics, nanoelectronics, and nanotechnologies while remaining the most cited scientist among all Moldovan researchers and developers (more than 13,000 citations of his work, including more than 7,500 citations over the past five years ). O. Lupan is also the author of a number of patents for inventions in the field of nanotechnology and nanocomposite materials, awarded high awards at a number of prestigious international salons and expositions. Research work of the group of the Technical University of Moldova under the leadership of O. Lupan has been carried out in recent years in close cooperation with partners from the USA, France, and Germany.

Valentin Oleshchuk

Dr. habil. V. Oleshchuk is engaged in the research and development of alternative methods and methods of control and modulation of powerful semiconductor converters of electric energy parameters for variable electric drive systems and the renewable electric power industry, being the Chief Researcher and Leader (from the Moldovan side) of 15 international research projects and programs in this areas. For more than eight years he has worked as a visiting research professor at a number of leading universities in Canada, the USA, Denmark, Italy, and Spain. The results of V. Oleshchuk’s work were reported and presented at representative scientific forums in more than 40 countries on all five continents.

Denis Nika

Professor D. Nika, the youngest representative of Moldovan science from the above four researchers, is a specialist in the field of physics of nanoscale structures, including the study of graphene-based structures, including the analysis of the thermal conductivity of graphene structures. He has a large number of publications in high-ranking publications in this field, including co-authorship with colleagues/partners from the United States of America. D. Nika is thus a promoter of the development in Moldova of the aforementioned promising area of research, the founders of which received the Nobel Prize in Physics in 2010.
