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 can and will include international guests as time goes by.

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, at a ripe 28 years old. Nina is the formidable architect (aka producer) of your regular Bingeing, and sits at a young 25 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. He does this by helping people achieve food security and economic empowerment through sharing knowledge. Caspar specialises in the sustainable intensification of smallholder farms in the developing world. 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, California and, of course, Australia - where he currently resides.

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 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 (In press) that provides an assessment of livelihoods and associated development pathways for communities of Ethiopia, Kenya, Tanzania, Malawi and Mozambique.
