About the host

who is binge thinking?

Technically, anyone and everyone is Binge Thinking. Guests are from all walks of life. They are mostly Australian, but the show is striving to include as many international guests as possible. To date, we’ve had guests from Nepal, Japan, America, Canada, New Zealand, and The Gambia.

Binge Thinking is brought to life each fortnight by sibling duo Caspar and Nina Roxburgh. The two are true millennials themselves, meaning Binge Thinking 'walks the walk' while 'talking the talk'. Caspar is the founding father and host of the show. He started the series when he was 27 after getting frustrated by a lack of younger voices in the global media. He’s now a ripe old age of 30 years old. Nina is the formidable architect (aka producer) of your regular Bingeing, and sits at a young 27 years old.  


By day, Caspar is an agricultural scientist who works on improving food security and agricultural land management of developing countries. His passion is to end hunger and rural poverty in the 21st century through more honest and open information sharing and storytelling. He does this by helping people achieve food security and economic empowerment through sharing meaningful and practical knowledge that can improve the amount of food and income available to them. Caspar specialises in the sustainable intensification of smallholder farms in the developing world. He is currently Research & Storytelling Director of Oikoi Pty Ltd - a socially oriented research and technology company working throughout the Asia-Pacific. His work has been published in academic journals and books, and he has spoken at international forums in North America, Europe, Africa and Australia. Caspar's work has been recognised through both awards and scholarships. He has lived and worked in Mozambique, the United States, Thailand, Japan, and, of course, Australia - where he currently resides. You can read more about his work here

What does he know?

Caspar completed a Bachelor of Agricultural Science (Honours 1st Class) and a Bachelor of International Development at La Trobe University and then spent four years doing a PhD at the University of Queensland which was conferred in early 2017. He worked for one year as a post-doctoral research officer at the Queensland Alliance for Agriculture & Food Innovation studying smallholder maize production in Eastern and Southern Africa. During this time Caspar co-authored a book Understanding Household Diversity in Eastern and Southern Africa (2019) that provides an assessment of livelihoods and associated development pathways for communities of Ethiopia, Kenya, Tanzania, Malawi and Mozambique. After this, he began work with the AgTech startup Oikoi Pty Ltd. He is currently Research & Storytelling Director. His role as Research Director involves designing, managing, and reporting on scientific research for governments, NGOs and private industry. His work as Storytelling Director involves producing photogaphy, prose, film, audio and overarching communciations strategies for programs that are changing the world.
