Graham convenes the Masters of Science Communication Outreach program. His research, teaching and engagement focusses on science communication and informal science learning. His current research and engagement investigates international capacity building and co-design in science communication. To this end, Graham founded the Science Circus Africa project which has trained 499 staff and reached 73,000 people in 10 African countries. He is currently widening his focus to the Asia-Pacific, primarily through ANU's Science Circus Pacific project. Graham also researches emotional and motivational aspects of science communication, particularly in settings like science centres, science shows and hands-on workshops, and using these methods to engage with social and environmental issues, along with teaching in these areas. He is an avid aficionado of science shows and has performed shows and delivered training globally.
