CURRICULUM VITAE

Oct. 2019- present
Assistant Professor
I study the behavior and physiology of marine predators using cutting-edge bio-logging techniques. I design and deploy novel marine biologging tags to understand the foundations of animal movements and quantify the kinematics of dynamic movements. I am also interested in the roles elasmobranch predators play in the energetic budgets of coastal ecosystems.

Hopkins Marine Station, Stanford University
2015- 2019
Research Scientist
I studied the movement and behaviors of large marine predators. I used cutting edge technologies (i.e., Saildrones, Wavegilders, camera tags, etc.) to describe the trophic and ecological interactions of top predators at remote atoll communities and pelagic habitats and I developed new techniques with these technologies for protection, monitoring, enforcement and management of remote marine protected areas.
Hopkins Marine Station, Stanford University
2011- 2014
Post-doctoral Researcher
I developed novel quantitative methods to assess population abundance of marine species to inform conservation strategies. Studied the physiology, population abundance and status, behavior, and movement of three species of warm-bodied lamnid sharks (Carcharodon carcharias, Isurus oxyrhincus and Lamna ditropis) using unique approaches with electronic and natural tagging techniques. Developed innovative tools to affect the intersection of science, education and the public.

Post-doctoral Researcher
Designed and developed a novel external tag that creates an artificial ambient magnetic field around fish in their natural environment and in controlled conditions to determine how sharks navigate during migrations using earth’s magnetic field and local foraging events using small-scale magnetic anomalies.
Determined energetic costs of migration, breeding and overwinter survival in free-living songbirds. Energetic expenditure is measured via heart-rate telemeters and behavior via continuous active tracking and focal sampling.
University of California, Davis
2004-2009
Developed methods to quantitatively assess data-poor marine species. Led a research team off northern California to determine life history, physiology, genetics, migration and an abundance estimate of white sharks, Carcharodon carcharias. Conducted the first quantitative assessment of thresher sharks (Alopias vulpinus) off California.

Shark Population Assessment Researcher
Analyzed diet composition from the Atlantic Sharpnose, Rhizoprionodon terraenovae, and Scalloped Hammerhead, Sphyrna lewini, to develop a model of early age and growth and feeding behavior. Conducted mark-recapture study on Bonnethead shark, Sphyrna tiburo. Analyzed shark vertebrae to gauge the relationship between age and growth for studies contributing to stock assessments.
