A native of the Quad Cities area of Iowa/Illinois, he obtained a Bachelor of Science degree from Northern Illinois University in the field of meteorology, and M.S. and Ph.D. degrees from Purdue University in the field of agricultural meteorology/climatology.

Dr. Andresen has professional experience as an agricultural meteorologist with the National Weather Service and with the USDA's World Agricultural Outlook Board in Washington, D.C., where he was involved in international crop/weather impact assessment and production estimation. He currently serves as director of MSU's Agricultural Weather Office and associated extension/outreach activities, including Administration of the Michigan Automated Weather Network (MAWN), a network of automated weather stations designed to provide quality, detailed weather data to the state's agricultural industry over the Internet.

The primary focus of Andresen's research has been the influence of weather and climate on agriculture, especially within Michigan and the Great Lakes Region. Current and past themes include; climatological trends and potential impacts, impacts associated with potential future changes in climate, weather and risk management in agricultural production systems, winter hardiness and mortality of crops and insects, and the measurement and use of weather data for determination of plant disease risk.
