As a public health precaution due to COVID-19, all Smithsonian museums are temporarily closed. We are not announcing a reopening date at this time and will provide updates on our websites and social media.
My research interests focus on the taxonomy, phylogeny and macroevolution of echinoderms, primarily sea urchins and sea cucumbers. I describe new species, infer relationships among varied taxa, and study the evolution of body plans and the processes that have influenced the geographic distribution of major groups through time.
