In the field: an interview with Roger Hanlon

Roger Hanlon is a Senior Scientist at the Marine Biological Laboratory, USA, where he investigates body patterning and colour change in cephalopods. After his undergraduate degree in 1969 at Florida State University, USA, he joined the US Army and travelled before completing his MSc (1975) and PhD (1978) at the University of Miami Rosenstiel School of Marine and Atmospheric Sciences, USA. After a NATO Postdoctoral Fellowship at the University of Cambridge, UK, in 1981, Hanlon joined the Marine Biomedical Institute, University of Texas Medical Branch, where he became a full Professor, before joining the Marine Biological Laboratory in 1995. Hanlon talks about the seminal experience in his early 20s that inspired his career and the methods and equipment he uses to study cephalopod camouflage and communication across the globe.
