Areas of Teaching
Research Methodology and Statistics (HE4411)
Nutrition and Metabolic Processes (FN4471)
Nutritional Epidemiology and Statistics (FN9711)
My research fits under the umbrella of nutrition knowledge and education. It can be
split into two main branches:
Nutrition education and knowledge of health care professionals related to pregnancy.
Specifically, I am interested in health care providers’ experience with nutrition
within their practice and how it compares to current trends.
Student educational experiences and ways to improve student learning, academic performance,
