Brief synopsis of current research:
The ecological and evolutionary problems that underlie my research interests include the convergent evolution of morphology, the manner by which organisms have adapted to their physical environment, and the physical aspects of energy transfer through ecosystems. At present, I am interested in the biofluid mechanics of inorganic carbon uptake in macrophytes, benthic-pelagic coupling in benthic bivalves, and hydraulic habitats in riverine environments.

(1) Mass transfer and the ecophysiology of benthic producers and consumers in aquatic ecosystems (funded).
(2) The effects of flow on aquatic plant productivity (funded).
(3) Biophysical structuring of habitats in Riparian Ecosystems (funded).
(4) Abiotic pollination mechanisms in aquatic plants (unfunded).
(5) The effect of biased random walks on spatial patterns (unfunded).
