Hannah was a graduate fellow of the Gump Station and conducted her field work for her dissertation at UC Berkeley Department of Integrative Biology in Moorea. She then was lucky enough to have a joint post-doc at the University of California Santa Barbara with the Santa Barbara Coastal Kelp LTER and the Moorea Coral Reef LTER and worked with Sally Holbrook and Russell Schmitt in Moorea for two more years. Hannah then spent a year as the Friday Harbor Labs post-doc at the University of Washington, before coming back to work in Moorea at CRIOBE as the Attaché Temporaire de Recherche et d'Enseignement. She taught an undergraduate Marine Biology field course for UCLA at the Gump Station in 2008. In April 2009, Hannah now has a position as a research scientist at the West Vancouver Lab of the Department of Fisheries and Oceans Canada with adjunct status at Simon Fraser University, and will continue to work in California and Moorea, as well as British Columbia.
Hannah is currently working on a project with BioCode collecting and identifying organisms associated with an increasing abundant tropical alga, Turbinaria ornata. This alga forms large rafts that drift from island to island and this may present a new dispersal vector for these, as yet unidentified associated organisms.
