Brief description of current research:

S. Elwynn Taylor is recognized throughout Iowa for his extraordinary efforts as an Extension Educator.  He is a recipient of the Iowa Distinguished Service to Agriculture award.  He is internationally known as a scholar of Bio-Meteorology and served as the Technical Editor of the Korean Journal of Forest and Agricultural Meteorology.  His contributions to the three-fold mission of the Land Grant University (Research, Teaching/Advising, and Extension) demonstrate the breadth of his expertise.

He is the recipient of the “Excellence in Extension Education” and “Excellence in Economic Education” awards.  He received the Iowa Regent’s professional achievement award. In 2003 he received the “Distinguished Service to Agriculture” award presented by the Iowa Farm Bureau (joining 3 other Iowa State University professors in this honor: William G. Murray (1987), Neil E. Harl (1992), and Louis Thompson (1995)).

Dr. Taylor is responsible for statewide leadership in the development and implementation of extension education and information programs in agricultural climatology.  I also have teaching responsibilities and full responsibility for off-campus graduate and undergraduate courses in Meteorology/Climatology.  Budgeted time during past 5 years: 100% Extension Education, divided between Integrated Pest management and Extension Teaching.  Advisor to 34 graduate students and member of more than 100 graduate committees during Iowa State University tenure.  Member of the Faculties of Agronomy, Ecology and Evolutionary Biology Program, and the Water Resources Program.
