He is a former Visiting Researcher from the University of Gdańsk, Poland, under the Marie Curie research fellowship. He has over ten years’ experience in QSAR, machine learning, and chemometric modeling studies in the field of drug design, toxicity prediction, and physicochemical property modeling. To this date, he has published over 70 research and review articles, 18 book chapters, and 2 QSAR textbooks. He is acting as a Reviewer for 50 peer-reviewed journals and has performed over 230 reviews. Prof. Jerzy Leszczynski is Professor of Chemistry and President’s Distinguished Fellow at JSU, Mississippi, USA. His research activities include studies of the nature of chemical bonds, theoretical predictions of molecular potential energy surfaces, structures of weakly bonded complexes, properties of DNA fragments, interactions of explosives with soil, properties, and toxicity of nanomaterials. He has published more than 1000 refereed papers in leading journals and more than 80 book chapters. He has edited and co-edited more than 50 books and has advised 31 students who already received their Ph.D. degrees. He has been cited almost 34,000 times and carries an H-index of 88 (Google Scholar). Among his international awards are: a Guest Professorship, Chinese Academy of Sciences, Shanghai, China 2002; an Honorary Doctorates, Dnipropetrovsk National University, Ukraine 2003, and Wroclaw University of Technology,  Poland 2013, Award of the Academic Council of the Taras Shevchenko National University (TSNU) of Kyiv, the most distinguished TSNU recognition, Ukraine 2013,  the Maria Sklodowska Curie’s Medal (Medal for prominent chemists working permanently abroad) Polish Chemical Society, Poland 2007, Honorary Doctorates, Wroclaw University of Technology, Poland 2016. He has been shortlisted for European Academy of Sciences 2002; International Academy of Engineering,2003; Ukrainian Ecological Academy of Sciences, 2003; and European Academy of Sciences, Arts and Humanities, 2004. He received White House Award in 2001 and the USA Presidential Award in 2009.
