Dr Craig Bunt is the Inaugural Professor of Agricultural Innovation, University of Otago, New Zealand. In 1995 he completed his PhD in Pharmaceutical Sciences at the University of Otago. After a period as a Research Officer with InterAg, a veterinary pharmaceutical company, he became a Senior Lecturer in Pharmaceutics at the University of Auckland, and following this a Senior Research Scientist at AgResearch.
Craig's research focuses on bioactive delivery, and he is an author on over 120 research publications and 16 patents (6 granted in the USA). Craig has been awarded many honours and distinctions including an OECD fellowship, The Chiasma, Uniservices and Ideas Challenge prizes of the Spark Ideas Entrepreneurship Challenge, the Waikato Agribusiness Innovation Awards Supreme Winner and the Controlled Release Society's Outstanding Veterinary Paper.
Research
Craig has a wide range of formulations experience over many years, clustered around three key areas; Veterinary Pharmaceutics, Agriculture, and Nutraceuticals, currently with a strong focus on electro-spinning/spraying and 3D printing. He leads the Ag/Vet Controlled Release lab, which researches agri and veterinary controlled release formulations.
Craig is also a member of Food Waste Innovation, a University of Otago Research Theme which measures food waste, develops reduction strategies, applies innovative technology, and works to modify producer and consumer behaviour.
