Abba Gumel was a full professor in the Department of Mathematics, University of Manitoba and uses mathematical theories and methodologies to gain insights into the qualitative behavior of non-linear dynamical systems arising from the mathematical modelling of phenomena.
He was a Full Professor in the Department of Mathematics, University of Manitoba, before becoming Foundation Professor of Mathematics at Arizona State University in 2014. He uses mathematical theories and methodologies to gain insights into the qualitative behaviour of non-linear 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) diseases of public health and socio-economic interest.
