Research Interests:
Professor Martin is interested in neuronal nutrient sensing mechanisms that are used to control food intake and obesity. Dr. Martin feels strongly and is passionate about the role of agriculture centers in partnership with biomedical sciences centers in developing the healthiest food production system available in the world.“Land-grant universities are at a crossroad that will likely take a major paradigm shift to become successful in the 21st century. What is needed is more attention to production, crop varieties and processing practices that improve the nutritional value of our food supply. In today’s global society it will be important to cultivate our best scholarly and creative approaches to dealing with the serious health issues which nutrition can impact, such as cancer, obesity, heart disease, diabetes, and malnutrition.” “Macronutrient-sensing mechanisms in the brain”
Current Projects:
- "Macronutrient-sensing mechanisms in the brain"
- Dietary Resistant Starch: The role of PYY and GLP-1 in energy balance
- Management of Core Laboratory for In vivo testing of bioactive compounds from Louisiana food products and botanicals.
- Development of High Through-put C. Elegans Bioassay of Bioactive Components from modified Food components and Botanicals
- Fermentable Fiber as a Calorie Restriction Mimetic: Nutrient Sensing and Lifespan.
- Neural regulation of protein ingestion
- Pre-biotic antimicrobial and histopathological effects of naturally occurring and synthetic oligosaccharidess on the gasto-intestinal system of animal models
