Dr. Tippery is a native of Denver, Colorado and has also lived in Texas, Washington, and Connecticut. He earned a dual Bachelor's degree in Biology and Classics from the University of Dallas in Irving, Texas, and a Ph.D. in Ecology and Evolutionary Biology from the University of Connecticut. His research interests include aquatic plants, plant systematics (i.e., understanding relationships among species and ancestral changes in growth form), plant developmental morphology, and plant reproductive biology.
