Systematics & Biodiversity
Understanding of the phylogenetic relationships and evolution among plants and fungi
Biodiversity resources such as the L.H. Bailey Hortorium are becoming ever more important for genomic study of biodiversity and evolution. The Hortorium's mission includes systematic studies of wild and cultivated plants, ethnobotany, molecular systematics, paleobotany, phylogenetic theory, biodiversity studies, and pharmaceutical studies of tropical plants.
- Chelsea Specht investigates the processes and patterns involved in the evolution and diversification of monocots, with a focus on the Zingiberales.
- M. Alejandra Gandolfo’s research centers on paleobotany, answering questions about the origin of angiosperms, the evolution of seed plant characters, and evolution of floras in the Southern Hemisphere.
- Kevin Nixon focuses on evolution and systematics of angiosperms with emphasis on the Fagaceae. He has also written software packages used for phylogenetic analysis.
- Jeff Doyle’s research concerns the origin and evolution of polyploidy in plants, also focusing on legume systematics and the evolution of nodulation
Cornell's long history as a center of mycology and the study of fungal diversity and taxonomy is carried on by the faculty and staff associated with the Cornell Plant Pathology Herbarium
- Kathie Hodge works on the biodiversity and ecology of fungi with a focus on insect-associated and food-spoilage fungi and is a national expert on fungal identification and poisoning
Soil Properties & Impact
Understanding soil properties and their impact on plant productivity, and soil microbial communities
Understanding the properties of soils, soil impact on plant productivity, and the soil microbial communities is foundational to both environmental conservation and food security.
- Dan Buckley investigates the soil microbiome and its impacts on ecosystem health, the plants we grow, the water we drink, and the air we breathe.

Understanding how microbes and other organisms interact with plants leading either to beneficial interactions or disease
