Helen Masey O'Neill (Edited By) Helen, known as Nell, graduated from the University of Nottingham with a BSc in Nutritional Biochemistry before going on to do her PhD, researching the influence of storage and temperature treatment on nutritional value of wheat for broilers. She progressed to postdoctoral research along with undergraduate teaching in equine science and animal nutrition at Hartpury College and later the University of Nottingham. This included supervising undergraduate and postgraduate projects which lead to her gaining accreditation with the Higher Education Academy in 2010. Teaching commitments continued into 2010-11. Nell's postdoctoral research at Nottingham included involvement in two DEFRA Link funded projects in feedstuff evaluation for pigs and poultry. Nell joined AB Vista in June 2010 as Research Manager where she is involved in managing research and development and regulatory trials for various AB Vista products.
