Research Interests

My interests in biology are diverse, but are founded in my training in plant physiology, biochemistry, and molecular biology. During my professional career I have studied the cell biology of amoebae, the physiology of Yersinia pestis (the bacterium that causes bubonic plague), the physiology and metabolism of the plant hormone indoleacetic acid and its derivatives, the role of cytokinins in the leaf morphology of Australian mistletoes, nitrogen fixation by bacterial symbionts in root nodules of soybean plants, and salt tolerance in celery and its wild relatives. During a sabbatical leave (2003-04) at the Research School of Biological Sciences at the Australian National University (Canberra, Australia), I became involved in a proteomics project, developing protein profiles of developing primary roots of Medicago truncatula.  I returned there in 2006 where I joined a project investigating the proteome of a transgenic strain of pea, modified to deter insect seed predators.

Although I officially retired in August 2005, I continued to teach courses in plant biology and biochemistry until 2008.  More recently I team-taught Natural History in the 21st Century: Galapagos Islands with Professor Sandra Madar in December 2011.  I also taught Intermediate Biochemistry in the spring of 2012.  In 2013 I taught Introductory Biochemistry, then team-taught Introductory Biochemistry with Professor Brad Goodner in the spring of 2014. 

In lieu of teaching, I am cataloging and preparing a website that will illustrate Hiram College's collection of plant fossils.

Traveling with Hiram College students to places of interest to biologists has been an important part of my teaching. I co-led three 12-week study abroad trips to Australia and one 3-week trip to New Zealand. In addition, I have visited the Galapagos Islands which led to a Hiram College trip there in 2003.  Since retiring I have been able to participate in Study Abroad programs to the Galapagos Islands (2006, 2009, and 2011), and to South Africa (2009). Photographs and accounts of some of these trips can be found on the Field Photos page.

Personal Interests

My other interests include outdoor sports and activities (sailing, hiking, biking), swimming, music, and gardening.  I have served as an assistant coach for the Hiram College men's and women's swim teams and I am a long-time member of the College's Chamber Orchestra, playing violin and viola.
