Degree PhD
Job type Research
Research Area(s) Biological Oceanography, Marine Ecology , Biological Oceanography, Marine Ecology
Research Activities I have a broad interest in systematics, evolution and diversity of the modern Asteroidea. Currently working on undescribed species from deep-sea settings in the Indian and Pacific Ocean. Although I focus on the Goniasteridae I am familiar with all groups and have published on nearly all of them. 
Skills/Expertise Systematics, Paleobiology, and evolution of the Asteroidea, Echinodermata (starfishes)including taxonomic identification, biodiversity, macroevolution, and ecology of asteroids
Comments Always looking for specimens to add to the NMNH collctions, and happy to help with identifications, especially where faunas are poorly known.
