My research focuses on marine and freshwater eel life history, biology, and behavioral ecology, and especially on eel larvae, called leptocephali. I analyze catch data of leptocephali in relation to ocean current patterns to learn about the biodiversity, spawning areas, larval distribution strategies, and recruitment mechanisms of eels. The potential effects of ocean-atmospheric changes on eel recruitment is also a focus, and I collaborate on otolith, isotope, migration, and genetic studies.
