Degree: Ph.D., Purdue University, 1993; M.S., Purdue University, 1992

Professional Positions:

Assistant and Associate Professor (1993-1999), Department of Biological and Agricultural Engineering, University of Arkansas

Research Interests:

Food engineering. The overall goal is to develop improved methods for design and operation of manufacturing systems for ready-to-eat food products, with a primary emphasis on improved microbial safety.  Current research focuses on modeling microbial inactivation, transport, survival, and growth for critical foodborne pathogens and products (e.g., Salmonella in low-moisture foods, E. coli O157:H7 on fresh produce, Salmonella in meat and poultry products). 

Instructional Activities:

BE 101 – Introduction to Biosystems Engineering

BE 350 – Heat and Mass Transfer in Biosystems

BE 478 – Food Engineering: Solids
