Abba Gumel is a Professor & The Michael and Eugenia Brin Endowed E-Nnovate Chair in Mathematics at the Department of Mathematics, University of Maryland, College Park. His research, which spans three main areas of applied mathematics (namely, mathematical biology, applied dynamical systems and computational mathematics), is focused on the use of mathematical modeling and rigorous approaches, together with statistical analysis, to gain insight into the dynamics of real-life phenomena arising in the natural and engineering sciences. The main emphasis of Gumel's work is on the mathematical theory of epidemics – specifically, he uses mathematical theories and methodologies to gain insights into the qualitative behavior of nonlinear dynamical systems arising from the mathematical modelling of phenomena in the natural and engineering sciences, with emphasis on the transmission dynamics and control of emerging and re-emerging human (and other animal) infectious diseases of public health and socio-economic interest.
