Research
Dr. Dickson has developed a predictive model to estimate the growth of salmonellae during the cooling of beef carcasses. This model was used during an evaluation of proposed USDA regulations, to determine the relative probability of salmonellae growth under a variety of cooling conditions. Dr. Dickson's studies of bacterial attachment, carcass washing and sanitizing have been applied to animal processing environments, resulting in the development of an inexpensive, technology neutral process which is very effective in controlling enteric pathogens on animal carcasses. Dr. Dickson has been involved in a variety of training courses, including hosting four International Atomic Energy Agency training fellowships in his laboratory, and teaching the principles of meat microbiology and HACCP to food industry audiences in Japan. He also traveled to the People's Republic of China and Singapore, evaluating meat processing systems. Dr. Dickson served on the National Academy of Science's panel on review of the use of scientific criteria and performance standards for safe food, where he served as chair of the Meat and Poultry sub-committee.

Extension
Dr. Hurburgh is the professor-in-charge of the Iowa Grain Quality Initiative
(GQI), a cutting-edge grain quality information (and research) program. Current
issues of GQI include public and private development of biotechnology policies,
standards, marketing incentives, and supply organizations. The GQI also is
developing country grain elevator management practices, TQM management,
and ISO certification for agriculture.
Research
Dr. Hurburgh is also the professor-in-charge of the Grain Quality Laboratory,
which provides analyses of the chemical and physical properties of grain,
primarily corn and soybeans. This lab is recognized as a world leader in basic
measurement science. Dr. Hurburgh's research interests include the physical
and chemical properties of biological materials, chemical and electronic
instrumentation, near-infrared reflectance analysis and sensors, chemometrics,
metrology, and statistics of very large databases.
Other Professional Interests
The Iowa Grain Quality Initiative and the Grain Quality Laboratory provide
leadership for rapidly growing specialty grain markets. By pursuing ISO 9000
and other certification systems, U.S. food producers can achieve important
competitive advantages. Additionally, precision sensing combined with rigorous
quality control documentation can be used to restructure markets and to meet
more individualized needs.
