About Me

I began my career in 1975 at Ohio Northern University as an Assistant Professor and then Associate Professor of Chemistry. Before moving to UNC Asheville in 1998 to fill the Phillip G. Carson Distinguished Chair of Science, I spent 15 years at Lyon College as the W. C. Brown, Sr. Distinguished Professor of Chemistry and Head of the Mathematics and Natural Sciences Division. I established the Pre-Health Professional Advisory Committee and served as the Director of the Pre-Health Professions from 1999 to 2008. From 2008-2011, I spent three years as a rotator at the National Science Foundation. I have spent my entire career teaching at liberal arts colleges because I believe they offer the most effective educational environments.

I am passionate about the critical role of student-faculty research in teaching chemistry to undergraduates. I believe that student research with a faculty mentor is the highest form of pedagogy. I have conducted research in the summer with undergraduates for 45 consecutive years and most of my publications have undergraduates as co-authors. I am co-author of a booklet commissioned by the Council on Undergraduate Research (CUR) titled “How to Get Started in Research at Undergraduate Institutions” that is now in its second edition. I wrote a chapter titled “Setting up and Managing a Research Program and Laboratory” for CUR book titled “How to Get Started in STEM Research with Undergraduates”.  I also wrote a chapter titled “Evolution of Undergraduate Research as a Critical Component in the Education of Chemists” in Sputnik to Smartphones: A Half-Century of Chemistry Education, Mary Virginia Orna, editor, Chapter 12, 2016, pp 219-238. ACS Symposium Series, Volume 1208.

Recently, I and other members of our department were invited to write a chapter titled “Transformative Impact of a Comprehensive Undergraduate Research Program on the Department of Chemistry at the University of North Carolina-Asheville ” in a book titled Best Practices for Supporting and Expanding Undergraduate Research in Chemistry, Bridget Gourley and Rebecca Jones, editors, Chapter 13, 2018, pp 227-241. ACS Symposium Series, Volume 1275.

Teaching Interests

I am a physical chemist who teaches Foundations of Physical Chemistry, and I take great pride in trying to be an effective educator. I also teach General Chemistry, First Year Seminar courses, and advanced courses in Atmospheric or Environmental Chemistry.  I have been honored with the following three teaching awards at UNC Asheville:  Distinguished Teacher Award in the Natural Sciences, Distinguished Teaching Award for the University, and the Board of Governors Teaching Award.

Research Interests

My primary research interests are in understanding the reaction mechanisms for both unimolecular and bimolecular processes and measuring/calculating rate constants for halocarbons that are (a) being considered as replacement compounds for CFCs or (b) are currently in use and will be banned in 2020 or 2030. In collaboration with Professor George Heard we have been funding between 7-9 students for 10 weeks of research each summer. My research has been supported for 26 consecutive years by grants from the Chemistry Division at the National Science Foundation and has generated over $3 million in external support. In 1992, I received the prestigious Chemical Manufacturers Association Catalyst Award for outstanding achievement in promoting undergraduate chemical education, in 2014 I was honored with the American Chemical Society Award for Research at an Undergraduate Institution, and in 2018 I was given the CUR Fellows Award in honor of our “internationally recognized research program involving undergraduates”.
