Dr. Hammerschlag's research centers broadly on the behavioral ecology and conservation physiology of marine predators. His current and future research has three primary foci: (1) understanding how predator-prey interactions structure marine communities (2) determining the habitat use and migratory patterns of large coastal sharks using biotelemetry and (3) understanding the underlying behavioral, physiological, morphological and biological mechanisms driving the movement decisions of marine predators. Other research interests include understanding how toxins biomagnify up the marine food chain and evaluating the susceptibility of different fishes to human threats (e.g. fishing and habitat destruction) and how best to mitigate these risks.
