Biography

Professor Emeritus Dr. David Parkhurst is a mathematical biologist with expertise in physiological plant ecology and statistics. He joined SPEA in 1973, a year after the school was founded, and served on the faculty for 32 years.

Parkhurst's research interests involve physiological plant ecology, including transfers of carbon dioxide and water between leaves and atmosphere and among the cells within leaves, both in relation to leaf structure. He also explores how mathematics and statistics apply to environmental issues such as analysis of concentrations of indicator bacteria at swimming beaches. Currently, Parkhurst recently analyzed data for coliform bacteria in the aqueducts leaving New York City's Kensico reservoir in relation to counts of gulls, geese, and other waterfowl there.

Since retiring in 2005, Parkhurst has cultivated his garden and started beekeeping. He is treasurer of the Bloomington Food Policy Council, and has just been appointed to the City of Bloomington Environmental Commission (on which he also served for 14 years long ago).
