Dr Graham Walker is a science communication teacher, researcher and practitioner based at the National Centre for the Public Awareness of Science (CPAS) at the Australian National University, where he convenes Postgraduate Coursework. He works at the interface of science communication and informal STEM learning, capacity building and co-development, emotion and motivation, and communication of social and environmental issues, particularly in informal learning contexts like science centres, science shows and hands-on workshops. Graham has been involved in science communication capacity building throughout the Asia-Pacific, Africa and the Middle East since 2003. He founded Science Circus Africa which, through dynamic partnerships with African organisations, has trained more than 500 staff and reached 73,000 people in 10 African countries, and more recently the DFAT-supported Science Circus Pacific. He is an avid aficionado of science shows and has performed shows and delivered training globally.


Research interests

- Science centres and informal science learning methods, e.g. science shows, hands-on workshops, interactive exhibits, making and tinkering, etc.

- Application of informal science learning methods to socioscientific issues such as climate, environment and health.

- Emotion and motivation in science communication and informal science learning

- Science communication capacity building, training, international development and cross-cultural codesign - especially in Africa, the Pacific and Asia.
