Plant evolutionary ecology; geographic range limits and rarity; population dynamics and community structure.

Molecular phylogenetic studies of fungi and evolution of fungal life history stategies.

Plant molecular biology, genomics and biochemistry. Natural products and chemical ecology of forest trees.

The study of plant form using the techniques of comparative genomics, molecular developmental biology and evolutionary biology.

Ecology and evolutionary biology; the distribution of biodiversity and the challenges posed to its conservation through recent changes to the environment.

Genome evolution, spliceosomal intron evolution, parasitic adaptation - focusing on microsporidia, a highly derived group of parasitic fungi.

My research examines the effects of human activity on global biodiversity, with emphases on (1) the behavioral responses of animals to human presence, (2) the effects of anthropogenic disturbance on predator-prey and other species interactions, and (3) the socio-ecological dynamics of conservation and coexistence. This work involves large-scale data synthesis and meta-analyses, and local field studies in North America and Africa.

Systematics and evolution of vascular plants, focusing on using DNA sequence data to infer relationships at deep and recent levels of seed plant, angiosperm and monocot phylogenetic history.

Early eukaryote evolution, molecular phylogeny, protistology.

Marine invertebrate zoology, protozoology, evolutionary morphology & phylogenetics.

Utilizing a combination of molecular genetics, biochemical and genomics approaches to understand the natural resistance mechanisms of plants against microbial pathogens including fungi, bacteria, and viruses.

The biology of viruses that infect marine phytoplankton and bacteria, and the role of these viruses in population dynamics and geochemical cycles.

Aquatic and Insect Ecology and Evolutionary Biology

• ​​We investigate the effect of changing environments on insect and aquatic communities
• We use field and laboratory experiments, syntheses of published literature, and natural history collections to investigate ecological and evolutionary responses to climate and habitat change
• Our work is grounded in ecological and evolutionary theory and we tackle both basic and applied questions

Plant Cell Biology and Molecular Genetics; organization of the cytoskeleton and its role in cell wall formation, intracellular motility and growth anisotropy in the higher plant Arabidopsis thaliana and the characean algae; plant responses to abiotic and endogenous signals.

Plant molecular systematic and evolution; the evolution of asexual polyploid complexes in higher plants.

We are interested in how local resistance and systemic acquired resistance are regulated in plants.
