My laboratory research focuses on molecular mechanisms responsible for muscle growth, development, and their relationship to inferior muscle meat quality. Our primary goal is to generate information that can be used by breeders enhance efficient production of high quality poultry meat. There is some evidence that intensive breeding of food animals for rapid growth rate and high feed conversion over the past several decades has led to inadvertent selection for traits which have led to meat quality problems, such as pale, soft, exudative (PSE) meat. We have developed a turkey skeletal muscle oligonucleotide microarray to investigate differences in gene expression from normal and PSE turkey meat samples. More recently, in a complementary approach, we have used RNA deep sequencing to analyze the transcriptional profiles of turkey muscle samples to determine the molecular basis for the differences in meat quality.
My laboratory is also engaged in studies on lipid oxidation and antioxidant chemistry, particularly in muscle food products. We are interested in identification of compounds from natural products that may serve as antioxidants in processed food products.
