Stochastic processes, mathematical biology, evolutionary theory (especially the levels of selection problem), community assembly, co-evolution and the evolution of virulence. My favorite study systems are the human microbiome, human financial markets, social media, and more.

Most datasets are described using the elementary basis - variables correspond to observations on the tips of the phylogeny.
I recently developed a method that allows researchers to describe their data in terms of variables corresponding to differential abundances along edges of the tree. "Phylofactorization" is a matrix factorization and constrained factor analysis where "factors" are putative functional ecological traits that arose along an edge in the tree. There's an R package on github and a tutorial

Patterns of Pathogen Spillover
Which pathogens spillover, which non-human reservoirs do they tend to come from, and how can we combine information at multiple scales ranging from reservoir ecology to human behavior for honest assessments of spillover risk?
