Overview

As professor and former chair of the Department of Horticulture, I am active in research and extension activities on production and handling of locally-grown cut flowers, as well as physiological disorders of vegetables and teach two 400-level courses.

Research Focus

My major research focus is on production and physiology of cut flowers and herbaceous perennials, with a minor emphasis on physiological disorders of vegetables, such as the effects of flooding on vegetable crops. Recently, we have investigated the temperature conditions in high tunnels (unheated plastic-covered greenhouses) and studied practical ways to moderate those temperatures.

Outreach and Extension Focus

High tunnel production of horticultural crops, especially cut flowers is a current interest, and the production of cut flowers in the Northeast. Growth and function of vegetable crops under New York conditions, especially as stressful conditions such as abnormally high temperatures occur, also require some attention. Extending knowledge about use of high tunnels for season extension and productivity of horticultural crops is becoming an important focus.

Instruction Focus

I teach a 400-level course on Physiology of Vegetables and Flowers (Hort 462), and coordinate the teaching of a mineral nutrition course (Hort 455) to senior undergraduates and graduates. I occasionally lecture in several other courses on photography, vegetable production, intercropping in the tropics, and season extension.
