Research interests ... simple List

Sampling techniques and methods
Phenology models
Crop yield-pest density functions
Insect population dynamics modeling
Information delivery methods

Research interests ... short narrative

My research is concentrated in three general areas. First, I am an interdisciplinarian in the Department of Ecosystem Science and Management. That allows me to use my quantitative and systems-level skills to work with colleagues in entomology, soil science, mineland reclamation, water quality, and rangeland ecology and watershed management. Second, I have various projects of my own that involve the development and use of various sampling projects, population models, and phenology models. Third, I enjoy writing computer programs that perform some useful tasks and some of those programs can be found on the World Wide Web (see below).
