Research Interests:

Research interests include tree physiology, nursery production, reforestation, establishment of plants in harsh environments, mycorrhizal symbiosis, and seed biology. Most of my work is with conifers, but increasingly my interests include native shrubs and tropical woody plants. I have over eight years experience in research with the forest industry, with work focused on reforestation and nursery production. I have been at NMSU 11 years, including three years as the Head of the Horticulture Department.

I teach Introductory Plant Science; Nursery Operation; Research Orientation and Perspectives.
