The overall goal of Dr. Gerrard’s laboratory is to maximize the production of high quality meat. Three distinct yet related approaches have been utilized to attain this goal. Ongoing studies range from understanding the basic biochemistry involved in the transformation of muscle into meat, to applied studies involving technology transfer for monitoring fresh meat quality. In addition, Dr. Gerrard’s research includes fundamental studies focused on understanding muscle growth and development, which directly affects ultimate meat quality. This multidisciplinary approach to meat science spans several domestic and international laboratories.
