Research Interests: Grain quality, marketing and distribution; value-added to grain through quality specification and traceability. Physical and chemical properties of biological materials, chemical and electronic instrumentation, near-infrared reflectance analysis, chemometrics, metrology, statistics of very large databases.

Public and private policy development-biotechnology policy, international Standards, marketing incentives, and supply organizations. Country grain elevator management practices.  Quality management systems and ISO.   Food system traceability.

Brief description of current research:

The instrumentation and product quality program presently includes areas of work: Near infrared spectroscopy calibration development and validation methods; Development of chemometric tools for calibration and standardization (uniformity) of multivariate measuring instruments; Testing of new applications for near infrared spectroscopy; Analysis, application, and mining of data generated from NIRS instruments; Training of international collaborators in NIRS methods.

The central theme of the certification, traceability and infrastructure projects is that application of auditable quality management systems with full traceability will create customer satisfaction in high value markets, improve operational efficiency and respond to security/safety threats; Development of ISO 9000 quality systems for agricultural industries; Analysis of constraints for isolation and traceability of grains
Supply Chain Conference in 2009; Stewardship of Transgenic Products-Traceability Protocol for Producers; Training in Storage and Biosecurity Issues.
