My research contributes to a growing effort to improve our understanding the historical and contemporary determinants of genetic structure in plant pathogens and fungi forming mutualisms with plants (mycorrhizae). My research has linked molecular techniques, in combination with field and laboratory experiments, to address questions at local and landscape scales including: (1) What are the contributions of historical, biological or ecological factors that promote population divergence and speciation? (2) How are communities organized and what are the factors contributing to structure and function?
Currently, I several research projects ongoing: 1) BioCode Moorea: collaborative project to barcode (tag all macrobiota and fungi with a DNA sequence); 2) hybridization of phylogenetic species of Armillaria mellea and , a wood decay pathogen, in eastern North America; 3) understanding historical factors affecting the genetic diversity of Russula brevipes (a mycorrhizal symbiont)in forests of North America
