Past research:
His first research assignment upon joining the Station was to evaluate the role of plants in reducing noise outdoors. Other research studies have been on the mechanics and strength of plant cells and hydraulic transport of solutes in rivers.

Current research:
Current research is centered on the aerial dispersal of spores and pollen in the atmosphere. The approach is to combine elements of meteorology and biology to derive aerobiological models for predicting probabilities of disease spread by plant-pathogenic fungus spores and for evaluating the transfer of genetic information in the environment by airborne pollen. Applications are to regional management of plant diseases and to deployment of genetically-modified crops.
