Education

Ph.D, Poultry Science, Texas A&M University
M.S., Animal Science, Prairie View A&M University
B.S., Animal Science, Prairie View A&M University

Research Interests

Environmental and waste management including air quality, molting of layer/breeder, and insect control. 

Academic Program 

Extension responsibilities include adult education programs in Nutrient Management Planning and Agro/Bio- security seminars. Coordinator of the Deep South Poultry Conference held at the Rural Development Center, Tifton, Georgia. Involved in the preparation and judging of 4H and FFA poultry judging contests as well as contributing to programs that assist county extension personnel.

Research programs focus on environmental and waste management issues associated with the poultry industry including air quality. Other areas of focus include the effectiveness of induced molting in broiler breeder and commercial layer flocks and darkling beetle control in broiler houses.
