I have been a member of the Zooniverse citizen science project team since the launch of the first Galaxy Zoo site in 2007. Zooniverse is a collection of online projects that allow volunteers from all over the world to contribute to meaningful, cutting- scientific research. Zooniverse volunteers have contributed to more than one hundred published studies – the project maintains a growing list at Zooniverse Publications.

My work with Zooniverse has led me to become an expert in understanding citizen scientists – who they are, why they choose to volunteer, and what they gain from their participation.
