I am a microbiologist/ecologist by training, and for 27 years I conducted laboratory-based research on molecular aspects of intracellular parasitism funded by NIH. I also teach courses in the medical school and in our school of public health (e.g., Parasitic Diseases; Medical Ecology; Ecology 101). Many of them deal with parasitism and its effects on large segments of the poor that live in the tropics. Controlling soil-based transmission cycles of helminthes that cause significant health problems throughout the world is of prime importance to me.

I left the lab in favor of working on more globally relevant projects that address some these important problems. Since it is generally agreed agriculture is solely responsible for so much environmental disturbance and serves as the interface for the transmission of geohelminths, one area of focus of mine has been on how to raise food without further encroachment into natural ecosystems.

I have established The Vertical Farm as a theoretical construct to look at the possibility of agricultural sustainability within cities. The idea grew out of a class project to measure the effects of rooftop gardening in New York City on reducing the dome of heat that develops over us each year. From that original idea, I expanded the concept to include urban agriculture and finally to multi-story indoor farming. I have given this project to my students in my course, "Medical Ecology."
