Sam Arnold

Hi, my name is Sam, I am from the Netherlands.

My previous research has been on a variety of different systems and species, including squid taxonomy, the role of sponges in reef metabolism, coral propagation, reef photogrammetry, and more. As a PhD candidate at the lab, my research focusses on how heatwaves and changes in complexity influence the neurophysiology, behavior and cognition of multiple functional groups on coral reefs. 

When I am not working I love to spend my time in the water; swimming and diving. When I am not in the water I enjoy going on hikes and reading.
