Mark Denny
Mark W. Denny (born 1951) is a professor of biology at Stanford University. His research applies biomechanics, fluid dynamics, and probability to problems in marine ecology, particularly the physical constraints experienced by organisms living on wave-swept rocky shores.
His research on the intertidal zone of wave-swept shores has led to increased understanding of this habitat. His most publicized research is his work on locomotion of water striders, which led to the coining of the term "Denny's paradox" to explain a discrepancy between capillary-wave-based propulsion models and the observed performance of juvenile water striders.
In 2008 he examined greyhounds, thoroughbred horses and human athletes trying to find their maximum running speed. He predicted the fastest possible time for men's 100 metres will be 9.48 seconds. Denny has served on the editorial board of the Journal of Experimental Biology.
