Research Interests

In order to be prepared for the consequences of environmental change on wildand cultivated plants, it is important to understand how plants respond developmentally and physiologically to conditions in the environment. My interests and research foci have been the modes-of-action of herbicides and the effects of temperature on the development and physiology of root systems using physico-chemical techniques and computer image analysis. I have recently completed studies which suggest that the environment has influences on internal timing mechanisms (biological clocks) which regulate stage specific developmental events beyond what can be attributed to thermodynamic considerations. I will be continuing studies on the effects of temperature and other environmental factors on the developmental anatomy and physiology of roots.

I am also interested in studying a wide variety of wild and ornamental plants that are currently growing where toxic materials are known to be present as a result of the previous landfill activities. It is my intention to begin studies on site that are designed to explore the effects of these conditions on root development and other aspects of plant development.

Finally, I have performed research on Arundo donax, the species used by woodwind musicians for the reeds of their instruments, on behalf of a major manufacturer of clarinet and saxophone reeds. Although it is not available publicly, this study revealed that a correlation exists between anatomical organization and the performance qualities of this material. I have recently begun interacting with members of the American Doublereed Society with the intention of performing a similar study for oboe and bassoon reeds. This work reaffirms my belief that science and art are not mutually exclusive.
