Our work spans three research themes:
1) DNA metasystematics: We gather biodiversity data through the analysis of marker genes from bulk samples (water, soil, and sediments). We pioneered this technique for benthic macroinvertebrates, used widely as bioindicators of aquatic ecosystems.
2) Biodiversity transcriptomics: We develop comparative transcritpome-based approaches for non-model organisms to gain insights on evolution of transcriptomes and understand molecular responses at ecological scale.
3) Bioinformatic approaches for biodiversity genomics data: We develop and test taxonomic assignment approaches for many taxonomic groups and marker genes, and develop tools to enhance analysis of metabarcoding and biodiversity genomic data through machine-learning methods and refined analysis.

My work spans five major axes of research:
1) The shape of the Tree of Life, including the relationships amongst species and the factors that influence the shape of this tree.
2) Major transitions in evolution, especially the frequency of transitions, the rate at which reversals occur, and the consequences of such transitions for molecular evolutionary patterns and speciation rates.
3) Evolutionary trends, with a focus on whether there are large-scale patterns in the history of life.
4) The diversity and integrity of freshwater ecosystems, including the diversity, distributions, traits, and origins of species.
5) The diversity of polar life, which I study using DNA barcoding to discover the true extent of arctic species diversity.
