BAE Profile: Bradley Marks


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
