Research Interests

I am generally interested in how plants function and how their function is related to their structure.  More specifically, I am interested how trees respond to herbivory and how their response is related to their structure.  For example, is there a link between the ratio of roots to shoots (leaves and stems) and stomatal closure in response to herbivory?  In the greenhouse, this work has involved studying different tree species, varieties of beans and varieties of tobacco with different root to shoot ratios and their responses to herbivory.  In the field, I have been collaborating with Dr. Richard Wilkens at Dowling College to study the effect of crown structure on bear oak’s response to herbivory.  We have also collaborated on a study to determine the effect of successive defoliations in one season on whole tree physiology of large white oaks.  These studies have been taking place in the Pine Barrens region of Long Island.  Very recently, I have been collaborating with Dr. Maurizio Mencuccini at the University of Edinburgh on a study to determine the effect of age on whole tree physiology.  This study addresses a fundamental question regarding what determines maximum growth in trees.  With the exception of the work in Scotland, all of my work has relied heavily on student participation.  In some cases, students have been included as co-authors on papers as a result of their efforts.
