Dr Alexander Rozenblyum, currently, an Associate Professor of Mathematics at New York City College of Technology, CUNY, where he has taught a broad spectrum of courses from developmental to upper-level for the past 20 years. Graduated summa cum laude from Belarusian University, Minsk, Belarus, with a master's degree in mathematics. Worked as a researcher at the Institute of Land Reclamation and Water Management in Minsk, Belarus, creating mathematical models of water flow in drainage systems. Earned a PhD in mathematics from Belarusian University. Then moved to Grodno, Belarus, to take up a position as a professor of mathematics at Grodno University. Earned a doctorate degree in mathematics from St. Petersburg University, Russia. Research interests are in the theory of special functions of mathematical physics and the theory of representations of groups, and contemporary methods of teaching in mathematics. Alexander is the author of more than 50 scientific and methodological publications in mathematics, including a research monograph Multidimensional special functions in the theory of group representations (co-authored with his brother, Leonid). In his leisure time, Alexander likes to listen to classical music (he graduated from music school, class of violin) and play table tennis.
