Abdullahi Muhammad Sirajo

Brief Biography

Muhammad Sirajo Abdullahi received his PhD in Applied Mathematics from King Mongkut's University of Technology Thonburi under the supervision of Prof. Poom Kumam (KMUTT, Thailand) and co-supervision of Prof. P. Christopher Staecker (Fairfield University, USA). He was a COMSATS/NMC Fellowship recipient (2014-2016) and Petchra PraJom Klao PhD Research scholar (2017-2020). Dr. Abdullahi has interest in algebra, analysis, geometry, topology, and their intersections. His research works revolved around digital topology and topological fixed point theory with their applications. Dr. Abdullahi is also currently interested in applied and computational topology – topological data analysis.

Area of specialization:Digital Topology, Fixed Point Theory and Applications
