Systematics, population biology, biogeography, and ecology of fungi.
 
My research program centers on the systematics, ecology and evolution of higher fungi and the mutualistic symbiosis that some of them form termed mycorrhizae. Four long-term projects are currently receiving most of my attention:
i) A survey of mushrooms and related fungi of the Costa Rican tropical oak forests. Goals of this study are to:
a) develop the first comprehensive survey of higher fungi from the neotropics; b) build scientific infrastructure in Costa Rica through training of graduate students and improving facilities; and, c) screen fungi for anti-AIDS and anti-cancer compounds. ii) A survey of mushrooms and related fungi occurring in northern Illinois and Indiana to determine species composition, distribution and host specificity and to assess the effect of air pollution on fungi in the region. iii) Comparison of biogeographic relationships between macrofungi of eastern North America and temperate eastern Asia. Goals of this study are to document macrofungal diversity in China and to determine the taxonomic similarity of the two regions based on detailed morphological analyses and analysis of DNA sequence data of selected taxa. iv) A monographic study of the genera Hydnangium, Laccaria, and Podohydnangium. This work is designed to test various theories of speciation, coevolution (with their obligate tree symbionts) and biogeography of fungi that form ectomycorrhizae. These projects entail an active field work component as well as laboratory studies that include micromorphological analyses (computer-aided light microscopy, SEM and TEM), examination of in vitro culture morphology, pairing studies and DNA sequencing. These interrelated projects are providing information on fungal ecology and biology that are crucial to temperate and tropical forest management and conservation.
