Professor Demchenko received his M. Sc. in Chemical Engineering from the D. I. Mendeleyev University of Chemical Technology of Russia, Moscow (1988) and his Ph. D. in Organic Chemistry from the N. D. Zelinsky Institute of Organic Chemistry, Russian Academy of Sciences, Moscow (1993). He was a post-doctoral fellow at the University of Birmingham, (UK) and a research assistant at the Complex Carbohydrate Research Center at the University of Georgia before joining the UMSL faculty in 2001. He was appointed Curators' Professor of Chemistry and Biochemistry in 2014.
