Biography
Arliss Winship is a researcher at the Marine Mammal Research Unit at the UBC-Fisheries Centre. He completed a Master of Science degree at the Marine Mammal Research Unit in 2000. His current research is primarily focused on bioenergetic modeling of Steller sea lions.

Specifically, he is developing bioenergetic models that can be used to estimate the amount of food that Steller sea lions consume and explore the relationships between food consumption and other components of a Steller sea lion's energy budget (e.g., growth and reproduction). His other research interests include population modeling and estimation of diet composition.
