History

Dr. Wiskin's training is in mathematical modelling, differential geometry, scientific computation, quantum  and field theory. In the past, he has modelled such things as acetylcholine release from neurons, and with the aid of several on-campus computers he is presently modelling electromagnetic, acoustic and elastic classical fields in various media with microstructure. These models can be used to image biologically, environmentally and medically relevant characteristics. He is also applying differential geometric ideas, via the computer, to various problems in nonlinear systems theory and optimization.
