It is often said that we are what we eat. Understanding how diet can affect physiology is my main research interest. To study the mechanisms by which diets modulate the function of the gastrointestinal tract we use in vitro and in vivo models. Our in vivo models are based on feeding animals with different diets, nutritional supplements or novel feed ingredients to evaluate how these nutritional manipulations change the epithelial cell composition, local immune response, expression of nutrient sensing molecules and hormone secretion of the digestive tract. We also use cell lines and enteroids (intestinal organoids or “mini-guts”) as in vitro models to understand the mechanisms of action of specific nutrients. We are also using swine enteroids as a model to study bacterial pathogens that cause disease in pigs. I believe that understanding the effects nutrients have on the function of the intestine will help us design better and healthier diets to improve human and animal lives.
Because research is better in collaboration, I am part of the Integrated Animal Systems Biology team.
Ongoing studies in my laboratory include:
- Effect of dietary fiber on intestinal cell differentiation and digestive function
- Effect of high fiber diets on the local intestinal immune response
- Effects of organic and inorganic zinc sources on the intestinal epithelium function
- Effects of diet viscosity on nutrient digestibility, intestinal cell differentiation, mucin production, and nutrient transporters in the swine intestine
- Use of swine enteroids as in vitro model of normal and pathological gastrointestinal physiology
- Use of enteroids to define the mechanisms of Lawsonia intracellularis pathogenesis
