Bachelor of Science, Biology, Dartmouth College, 2005
Ph.D. Hopkins Marine Station, Stanford University, 2013

My PhD work at Hopkins Marine Station (completed April 2013) used various chemical tracers, including stable isotopes and Fukushima-derived radionuclides, to examine the migration patterns and trophic ecology of pelagic predators in the North Pacific Ocean. 

I am currently an NSF Post-Doctoral Scholar working collaboratively with researchers at the University of Hawaii, NOAA, and Stony Brook University.  I am based at the School of Marine and Atmospheric Sciences at Stony Brook University, where I continue work using chemical tracers (stable isotope analysis (bulk and compound-specific), mercury, and Fukushima-derived radiocesium) to elucidate migration patterns of Pacific predators, particularly Pacific bluefin tuna Thunnus orientalis.  We are investigating the potential transport of radiocesium from Fukushima in a broad suite of predators including marine mammals, salmon, turtles, sharks, and various tuna species.

Our group also studying the dymanics of radiocesium flow in marine biota close to the Fukushima plant.  By reconstructing food webs and measuring Cs activity in water, sediment, and organisms at various trophic levels, we are examining the role of sediment as a persistent source of Cs to marine organisms.
