As a lecture-line faculty, I do not maintain a research laboratory. My interests, however, are in ornamental horticulture, green roof gardening, urban ecology, biodiversity, the flora of the Cape Region, and ornithophily. I have worked on the systematics of Melianthaceae focusing on Melianthus, an enigmatic shrub from Southern Africa with unusual black and brown nectar, and am currently exploring Leonotis, a polyphyletic genus that ranges from S. Africa into Ethiopia. My doctoral research was based locally at Van Cortlandt Park where I increased the floristic count from 355 taxa to 1117 taxa, and rising . In addition, I have work experience from three botanic gardens on three continents coupled with 30 years as a rooftop gardener in Manhattan. At Lehman, I have worked with the Minority Association of Pre-health Students for 10 years.
