During my tenure at University of North Carolina at Chapel Hill, I taught several courses:

• Environmental Protection -- This was a very large undergraduate course that covered the full breadth of environmental science and protection.  The course emphasized the science behind all issues of environmental degradation as well as environmental health effects on humans.  It was very well received by the students and a complete joy to teach.

• Environmental Health (residential) --This course emphasized the human health effects of environmental degradation.  It was a graduate course taken by most of the graduate students in the School of Public Health.  This was very difficult for me to teach because my main interest in in the health of environments not humans.  Nevertheless, it seems to have been successful in informing the students of the human health consequences of changes in the environment.
• Environmental Health (online, distance learning) -- Toward the end of my career the environmental health course was modified and offered as an online course.  This was one of the first online, distance learning courses at the University.  I had as many as 150 students in 10 time zones around the world!  It was very exciting to develop and improve this course.

• Biology for Environmental Sciences -- This course was designed for environmental engineers and scientists who had very little background in biology.  The course was mainly environmental microbiology and ecology.  I emphasized my practical experience in working with these kinds of systems.  We considered drinking water treatment, wastewater treatment, and water pollution.  Many of these budding environmental engineers tour their first wastewater and drinking water treatment plant while taking this course.
• Limnological Courses -- Early in my career, I developed and taught a graduate course entitled "Limnological Methods and Analysis".   This course was largely a field course that emphasized the techniques used to characterize aquatic systems as well as the interpretation of the results of such analyses.  It was largely taught in a Socratic style.  I believe it was my best course, but fewer of our graduate students were interested in such field studies.  I briefly taught a basic linmology course as well.
