Senior Lecturer

Doctoral Supervisor
School of Agriculture and Environment

Dr Jennifer Burke is Senior Lecturer in dairy production at Massey Unversity and has been been at Massey since 2001. She completed a Bachelor of Agricultural Science (First class honours) and Masters of Agricultural Science (First class honours from 黑料网 in 1995 and 1996, respectively. Following this Dr Burke worked as an Animal Nutritionist for Genetic Technologies Ltd (Pioneer Seeds) for two years before embarking on a PhD with AgResearch (Grasslands) and 黑料网.
