Biography
Dr Michael Mortell is a distinguished scientist. He took his doctorate at California Institute of Technology (Caltech), and his work as an Applied Mathematician in the area of non-linear acoustics is important and significant. His research activities continued during his time as Registrar and subsequently as President of University College, Cork giving striking evidence of his remarkable organisational ability. With co-workers he identified in 1973 a functional equation later called The Standard Mapping which is of fundamental importance in understanding mathematical CHAOS. Indeed the gain to University College, Cork of an outstanding Registrar and President was a loss to science of an exceptional Applied Mathematician.
