About Charles "Chris" B. Keil

After graduation from Wheaton College in 1987 Chris worked on National Toxicology Program research projects prior to attending graduate school at the University of Illinois at Chicago.  During his time in Illinois Chris was a member of the Illinois Army National Guard.  After his graduate studies Chris began teaching in the Environmental Health Program at Bowling Green State University in Ohio.  While there Chris taught a variety of environmental health classes including: Industrial Hygiene, Air Quality, Environmental Assessment Methods, Epidemiology, Industrial Ventilation and others.  Chris was also adjunct faculty in the Occupational Hygiene Program at the University of Toledo Medical Center where he taught and directed student research. 

During the summers while Chris was at BGSU he also taught at the Wheaton College Science Station in the Black Hills of South Dakota.  He was himself a student there in 1985 and finds some of his deepest professional and personal contentment in the vibrant Christian living and learning community that exists there each summer.

Chris enjoys working internationally and has taught short courses and done research in Ethiopia a number of times.  He has also taught in Norway, Germany, Hungary and Moldova.

Chris  enjoys hiking, outdoor activities, model building and playing strategy games.  He and his wife Maureen both enjoy gardening, traveling, and spending time with students.

Research

Chris’s research centers around the topic of environmental pollution assessment.  He is currently doing work on the transport of indoor air pollution.  Recently has worked on projects on the measurement and statistical interpretation of pollutant levels in Addis Ababa drinking water, shallow wells in Northwest Ohio and indoor and outdoor air pollution in Ethiopia.

Chris has also done research in science education.  He was one of the directors of a NIH funded project that developed and implemented problem based learning units addressing locally pertinent environmental problems in 5th through 9th grades.  The project demonstrated that contextualized, interdisciplinary hands-on / minds-on learning improves students environmental awareness, standardized tests scores and scientific process skills.
