Dr. Yelizaveta Chernysh started her professional career in 2013 as an assistant in the Department of Applied Ecology at Sumy State University (SSU), Ukraine. She is currently an associate professor in the Department of Ecology and Environmental Protection Technologies at SSU. She also works as a head of the International Innovation and Applied Center "Aquatic Arteria".

In June 2019 she successfully defended the thesis on “Scientific basis of environmental synergetic approach to phosphogypsum recycling to reduce manmade load on environment” for the degree of Doctor of Technical Sciences in Ecological Safety. The defense was held at the session of Dissertation Council D 55.051.04 at Sumy State University. Previously, she obtained her Ph.D. in Ecological Safety, with a thesis on “Sewage sludge utilization by sulfidogenic association of microorganisms”. She had obtained her Master's in Ecology and Environmental Protection in 2010 (with a thesis on “Simulation of sewage sludge biotransformation for energy purposes” in 2010, and her Bachelor's in Ecology in 2009 (with a thesis on “Environmental aspects of hydrogen energy”), both also from Sumy State University.

In the framework of the Erasmus⁺ program, Dr. Yelizaveta Chernysh took part in the international seminar "Materials and Environment", University of Koblenz-Landau (Germany) in June 2016.

During October 2016, she received an internship under an individual grant from the Government of France at the Laboratory of Automation and Technology of the University of Claude Bernard, Lyon, France.

In 2018, she carried out scientific research training at the Institute of Environmental Engineering of the Technical University of Košice, Slovakia, under the National Scholarship Programme of the Slovak Republic.

Dr. Chernysh was awarded a scholarship of the Cabinet of Ministers of Ukraine (2018).

In 2019, she was awarded two international scholarship programs: the Matzumae International Foundation and the German Academic Exchange Service scholarship program. Support under these programs was provided to Chernysh Ye. scientific research at Chubu University (Kasugai, Japan) and Technical University of Berlin (Berlin, Germany) respectively.

Her research activity focuses mainly on technologies and processes of environment protection, in particular the biotechnologies of waste recycling, with special attention being paid to the pre-treatment and utilization of waste/by-products for bioconversion with the production of bio-based products (biogas, bio-fertilizer, bio-sulfur, etc.). The sphere of her scientific interests also comprises the theoretical and practical aspects of the synergetic concept of nonlinear ecosystems processes, which include the estimation of anthropogenic impact.

Yelizaveta's publications reflect her research interests in the biotechnology of waste recycling and non-linear modeling of ecosystem processes. She has international publications on this subject, and technical solutions have already been confirmed by patent documents. She teaches several courses on the safety of the vital activity, biotechnology, environmental biotechnologies, basics of bioethics and biosafety, environmental economics, and municipal environmental activities.

Over the period of scientific and pedagogical activity (2011-2021) Yelizaveta Chernysh has 158 scientific works, including 7 collective monographs (books), 1 textbook, 58 articles in scientific and foreign peer-reviewed editions, 19 articles in the editions indexed by international scientometric databases Scopus and / or Web of Science, 4 patents for utility model and 3 patents for invention, 66 abstracts of reports in the conference proceedings.

She is a member of the International Editorial Advisory Board of the Cambridge Scholars Publishing (UK) and a reviewer of the scientific publications International Journal of Energy for a Clean Environment (ISSN Print: 2150-3621; ISSN Online: 2150-363X); the Journal of Solid Waste Technology and Management (ISSN: 1088-1697); the International Journal of Hydrogen Energy (ISSN: 0360-3199); the Journal of Engineering Sciences (ISSN Print: 2312-2498, ISSN Online: 2414-9381). She is also a member of the Solid Waste Association of North America (USA), Hong Kong Chemical, Biological & Environmental Engineering Society (China), and International Association for Technological Development and Innovations (IATDI) (Ukraine).
