Roger T. Hanlon
Roger T. Hanlon is senior scientist at the Marine Biological Laboratory and also holds a faculty position at Brown University in the Department of Ecology and Evolutionary Biology.
Hanlon is a leading expert on cephalopod (octopus, squid, and cuttlefish) behavior, especially their camouflage abilities, which are unmatched in the animal kingdom. His laboratory conducts field studies of cephalopods as well as a wide range of laboratory experimentation to quantify field observations, including their mechanisms of visual perception and sensory integration as well as the functional morphology of the complex skin that produces the changeable body patterns. Hanlon’s laboratory is highly collaborative and works at multiple levels of integration: from molecules to behavior to whole organisms (the lab’s primary focus) to ecology.
He has authored 230 scientific papers and co-authored two books: Octopus, Squid and Cuttlefish: A Visual Scientific Guide to the Oceans Most Advanced Invertebrates (2018) and Cephalopod Behaviour (2018).
