Biography

Natalie joined UNE in September 2015 as a Post-Doctoral Research Fellow. Her main area of interest is broiler nutrition, particularly focusing on feed enzymes and carbohydrate chemistry. She completed her doctorate thesis (2010-2014) and a year as a Post-Doctoral Research Fellow and Lecturer (2014-2015) at Nottingham Trent University, England. Her current research focuses on non-starch polysaccharides and the effects of xylo-oligomers in broiler chickens.

Research Interests

  • Impact of dietary fibre on poultry health and perofmance
  • Assessing factors that cause variation in feed ingredients used in poultry diets, particularly focussuing on non-starch polysaccharides and phytate
  • The use of xylanases to produce xylo-oligomers and the effects of xylo-oligomers on gut microflora and performance in broiler chickens
  • Alternative feed ingredients for use in poultry feed formulations
  • The influence of gastrointestinal pH on nutrient bioavailability and the intestinal microbiota in poultry
  • Evaluating phytate and xylan ‘susceptibility’ to the effects of enzymes and assessing factors that influence  reactivity and enzyme efficacy
  • Developing in vitro models to determine digestibility of poultry diets

Research Supervision Experience

Principal Supervisor 2 PhD and 2 Masters students
