Research Interests

Research at Small Colleges
     The role and value of research varies with the institution.  The purpose for conducting research at a PhD granting institution is much different than is the purpose at a liberal arts university.  In the former case, research is used to attract and train graduate students, to help fund the department, to bolster the university's reputation, to satisfy the investigator's curiosity, and to enhance his standing in the field.  In the latter case, research is useful for teaching the principles of scientific investigation, for giving the students real experience with asking manageable questions of nature and coaxing answers from her, and for providing the faculty member with a reasonable means of satisfying his own curiosity as well.
Students in Research
     Some students benefit greatly from prolonged, close work with a professor on a research project.  Careful, individualized mentoring generally is most possible in a teaching environment, where a faculty member has fewer students and less at stake in the outcome of a project than at a research university.  I have seen several examples of undergraduates doing "research" in major research labs; they rarely saw their professors and usually were just assigned routine support tasks for the graduate students and post-docs.  It is doubtful whether they learned very much.  At a teaching university, however, the professor and undergraduate student can busy themselves more with the process of discovery.  A seemingly simple thing like learning how to design and carry out a controlled experiment can greatly improve a student's understanding of how the validity of conclusions depends upon the quality of the data, and how the quality of the data in turn is subjet to the limitations of the methods.  This understanding is at the center of experimental science and often is best learned slowly and sometimes falteringly, without too much being at stake for the student or the professor.

My Projects
         My research interests include a large number of potential projects which can be completed by one or two undergraduates, with luck and hard work, within a year.  In three instances in the past five years, these projects have resulted in publication in refereed journals.  I think it is important to give undergraduates meaningful projects -- that is, ones which don't simply reinvent the wheel.  In that way the students are engaged on the edge of knowledge, which adds excitement, challenge and the potential of publishing in a respectable journal to the project.  I have well-established projects which deal with Bacillus thuringiensis spores and hydrocarbonclastic bacteria from a unique oil seepage site.  A dozen or so undergraduate students have been involved in these projects.  Additionally, I have recently been involved in study of the ecological connection between phytopathogenic bacteria and Tardigrada, again with involvement of undergraduate students.  Most of these students involved in meaningful research have come away with a better understanding of the scientific process and improved laboratory skills.
