Research interests

I am a supervising marine ecosystem research coordinator with NOAA's Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division in Honolulu, Hawai`i. I have a Bachelor’s of Science from the University of Michigan, and a Masters of Environmental Management from the Duke University Nicholas School of Environmental and Earth Sciences. I'm also an external PhD candidate at Curtin University, Department of Environment and Agriculture, based in Perth, Western Australia.

From 1995 – 2002, I was involved in a variety of marine science programs, including phytoplankton/cyanobacteria research at the Heinz Steinitz Marine Biological Laboratory in Israel, a fellowship at the Bermuda Institute of Ocean Sciences examining coral disease frequencies, a Sister Exchange Program between the Chugach National Forest in Alaska and the Magadan Marine Preserve in Russia, and commercial fisheries research as a NOAA Fisheries Observer in Alaska.

Between 2002 – 2012, I worked primarily with NOAA, with research focused on an array of projects ranging from marine debris mitigation in the Papahānaumokuākea Marine National Monument to shallow water benthic habitat/reef fish assessments in Hawaii and the US Pacific Territories (American Samoa/Guam/the CNMI).

Since 2012, my interests remain focused on coral reef fishes, particularly deeper water (mesophotic) coral reef fish communities, roving predator demographics, size structure/species composition of fishery targeted species, and the effects of fishing pressure.


  Please note that only publications relevant to mesophotic reefs are indexed.
