Ellis Cumberbatch earned his PhD in Applied Mathematics at the University of Manchester in 1958, under the renowned Sir James Lighthill, Fellow of the Royal Society. His dissertation foretold the design of an ocean-going ship hull that would allow it to travel in excess of 230 miles per hour. Since that time, his mathematical contributions and research interests range from differential equations and fluid mechanics to semiconductors and industrial modeling. He has published widely and supervised research conducted under grants from the National Science
Foundation and Douglas Aerospace Corporation.
Cumberbatch arrived in Claremont in 1981, after holding positions at the California Institute of Technology, the Courant Institute of Mathematical Sciences, Leeds University, and Purdue University. With Jerry Spanier, he revitalized the Institute of Mathematics Sciences, implementing an applied focus that thrives to this day. He created the PhD program in Engineering and Industrial Applied Mathematics; his vision and foresight were instrumental in starting the Financial Engineering program, the PhD in Computational Sciences, and the Claremont Center for Mathematical Sciences. He has served as dean, department chair, and director of the Mathematics Clinic.
