A favorite PLACE of mine.

My mugshot if you are interested.

Below is a live-camera view of my office.

Research Experience

I am a microbiologist whose graduate and postdoctoral training was in microbial physiology and molecular biology, and my research interest remains there. My research effort specifically focuses on how bacteria regulate their growth and how their mechanisms of growth regulation allow them to cope with their environment. I have been fortunate to have had a host of undergraduate and graduate students work in my laboratory. Of the research accomplishments of my laboratory, I think the following ring my bell the loudest.

While at Kansas State University I have received grant support from BioServe Space Technologies, AlliedSignal Aerospace, Eli Lilly and Company, The National Science Foundation, The Bureau of General Research at Kansas State University, Research Corporation, The American Cancer Society, Inc., Kansas Division, American Cancer Society, Inc., The Nitragin Company, S.C. Johnson & Son, Inc., Pharnum Companies, the Kansas Racing Commission, and the Kansas State University Research Foundation. A United States Patent has been granted for my rhizobial mutants which display enhanced nodulation.

Teaching Experience

I am in charge of teaching the Division of Biology's General Microbiology course. The course is a lecture (60%) laboratory (40%) course of 4 credit hours, and is the beginning course in the microbiology degree program. The course is offered in both the fall and spring semesters, and in the twenty plus years I have taught the course, over 8,000 students have enrolled. The course syllabus, sample exams, and lecture notes can be found on the Internet at the General Microbiology Homepage.

In the fall of 1997 I began offering a new, undergraduate, general education course in Public Health Biology. The course syllabus, assignment list, and lecture notes can be found on the Internet at the Public Health Biology Homepage.

I also assist in teaching the Division's beginning biology course, Principles of Biology.

In 1976 I was awarded a grant by NSF to develop, with the assistance of John Eads, an instructional technologist,an "Individualized Laboratory Course in Microbiology."
