Prof. Dr. Engin Özkan | Number Theory | Best Researcher Award

Head of the Department of Mathematics | Marmara University | Turkey

Prof. Dr. Engin Özkan is a distinguished mathematician specializing in number theory, combinatorics, and polynomial structures of number sequences. His research explores the properties and transformations of Fibonacci, Pell, Jacobsthal, and Lucas-type sequences, along with their applications in finite groups and algebraic structures. Through his extensive academic career at leading institutions in Turkey and abroad, including Marmara University and The Ohio State University, he has contributed significantly to the development of generalized number sequences and their combinatorial representations. Prof. Özkan’s studies advance the theoretical foundations of sequence polynomials and trace formulas, bridging classical and modern mathematical theory.
