Research and Professional Interests:

Gompertz kinetics, based on the idea that exponential processes generally proceed at exponentially changing rates, provides elegant models for description of numerous biological relationships. Recently explored examples appear in the list below.

Recording and interpretation of externally recorded biopotentials is conveniently done with suction electrodes. Simple apparatus using this method, which is especially suitable for teaching purposes, has been developed in this laboratory.
