Ryan is currently a faculty member at the Department of Business Mathematics, Universitas Prasetiya Mulya. Before that, he was trained at Queen Mary, University of London, and before that he obtained his master degree at both Bandung Institute of Technology and Kanazawa University. His primary research lies in the grey area of mathematics and physics, namely on noncommutative geometry using the tools of Hopf algebras. However, he is interested in almost all areas of mathematics, including linear algebra, number theory, discrete mathematics, and their applications.
