Board Certification: Diplomate of the American College of Poultry Veterinarians (ACPV)
Extension responsabilities:
Broiler nutrition & management, and nutrient & waste management.
Educational programs under my coordination:
The Poultry Decision Makers Workshop Series: Mathematical Modeling & Operations Research in Poultry Production
The Carolina Poultry Nutrition Conference, Poultry Nutritionists Round Tables, Workshops and Seminars hold periodically throughout the state and abroad.
Topics include:
1) Broiler nutrition & feeding, and broiler health & management;
2) Effects of broiler breeder management and nutrition on broiler performance;
3) Effects of hatchery and incubation management on broiler performance, bone development and welfare:
4) Evaluation of efficacy of feed additives and nutritional factors that affect enteric health and meat quality. This includes evaluation of coccidiostats, antibiotics, probiotics, prebiotics, symbiotics, crystalline amino acids, vitamins, trace minerals, and vaccines against Eimeria spp.
5) Technologies to improve broiler house air quality and reduce gas emissions.

Research Interests:
My research goals are:
1) To understand mechanisms of nitrogen and amino acid utilization, to improve efficacy of low crude protein diets in broiler chickens and minimize nitrogen environmental impact, including air emissions;
2) To develop computerized growth models to be used as tools to determine economical optimal management practices and feeding programs;
3) To evaluate feed additives, feedstuffs, feed processing methods, and their effects on intestinal pathobiology, specific immunity against Eimeria spp., gut microbiota dynamics, and microbial uricase activity;
4) To estimate the optimum dietary electrolyte balance and mineral requirements for optimum performance;
5) To improve the understanding of avian bone development and leg disorders in broilers and turkeys.
