Report of visit Prof. James Keener

by Mark Peletier, CWI Amsterdam,

During the month of June, Professor James Keener (University of Utah) was an honorary visitor of the Centre for Mathematics and Computer Science (CWI) in Amsterdam.

Professor Keener is a specialist on mathematical aspects of physiology (see e.g. his book, in collaboration with James Sneyd, Mathematical Physiology, Springer, 1998). During his stay in Amsterdam he was actively involved in a variety of current research projects at the CWI (see, and also spawned a couple of new ones. As an example, a conversation with Frank Bruggeman (VU-Amsterdam) sparked a new research project on the relation between ultra-sensitivity, scaffolding, and diffusion in signal-transduction processes. As another example, combination of work that Professor Keener had started earlier, and interests present at the CWI, led to a collaborative project on mechanical aspects of biofilm growth.

In addition to these informal activities, Professor Keener presented a series of lectures entitled Cardiac Electrophysiology and Arrhythmias in which he gave a basic introduction to wave propagation in cardiac tissue, and analysed both the normal function and a number of well-known arrhythmias in terms of the spatial properties of the associated wave patterns. He was also a speaker at the first MAS Crossroads Colloquium Modelling and Analysis in the Life Sciences (June 7 2000, at the CWI-Amsterdam).
