Research Interests

Areas of research interest focus on pre- and post-harvest methodologies that impact factors considered traits of value to the red meat industry and red meat animal producers.  Current programs of interest include:

1. Pre-harvest production and management factors that affect lean meat yield, quality and profitability for beef and pork
2. Identifying methods to increase the value of red meat products through muscle profiling
3. Cellular mechanisms responsible for meat tenderness and quality
4. Investigation of pre- and post-harvest food safety strategies

Courses Taught

-ADSC 1050 The Meat We Eat
-ADSC 3650 Introduction to Meat Science
-ADSC 6890 Advanced Meat Science
