Career overview
Richard undertook a degree in General Zoology (BSc Hons) at the University of Aberdeen, before working as a research assistant on the University of Cambridge’s meerkat project. He then completed a NERC funded MSc scholarship in Ecology at the University of Wales in Bangor, before taking up a research post at the Central Science Laboratory. He undertook a PhD at the University of Brighton on the impact of game ranch management on small mammal population dynamics, before becoming the CEO of the Badger Trust. Richard joined NTU in 2007 as a Lecturer, where he undertook a Post Graduate Certificate in Higher Education (PGCHE) and became a Fellow of the Higher Education Academy (FHEA).
