How is marine biodiversity generated and maintained?

My research

I use genomics to understand the origins and persistence of marine biodiversity.

I am an evolutionary biologist working at the intersection of comparative genomics, phylogenomics, and marine conservation. My research uses cnidarians - corals and jellyfish - as model systems to investigate how new cell types evolve, how marine species diversify, and how interactions between animals and their microbial partners shape life in the ocean.

Research themes

Understanding biodiversity across biological scales

My work connects evolutionary processes within organisms to the ecological and evolutionary dynamics that shape marine communities.

Medusa in the Podocoryna life cycle

Cell-type evolution

How did animal cells and tissues evolve?

At NHGRI, I study the hydrozoan Podocoryna using genome resources and single-cell RNA sequencing to investigate cell-type diversity, differentiation, and the evolution of specialized tissues such as striated muscle.

Biodiversity & conservation

What processes drive speciation in marine invertebrates?

I apply phylogenomics and museum genomics to resolve species boundaries in Pocillopora corals, connecting evolutionary history to coral distributions and conservation.

Host–microbe interactions

How do symbioses shape animal biology?

My work investigates how host-associated bacteria and other microbes impact host physiology, immune responses, and evolutionary diversification.
