Research Interests

My research program integrates phylogenomics, community ecology, and conservation biology to interrogate these fundamental mechanisms of diversification, using lichen-forming fungi as a premier model system. While lichens have traditionally been viewed through a morphological lens, I utilize genome-scale data to deconstruct the 'holobiont,' revealing how hybridization and symbiotic partner-switching drive ecological success in extreme environments. By resolving the evolutionary histories of hyper-diverse clades and modeling the resilience of 'cryptic' lineages, my work aims to bridge the gap between organismal natural history and theoretical evolutionary biology, providing predictive frameworks for biodiversity in the Anthropocene.
