Griffiths has worked in various aspects of food processing and post-harvest systems’ engineering in the past.  At present, he directs a research program focused on engineering and optimization of innovative processing strategies to maintain food, feed and pet-food quality, and prevent mycotoxin contamination, especially for grains. Research scope encompasses development of novel techniques for detection, decontamination and detoxification of harmful grain molds and mycotoxins; study of kinetics of grain quality degradation and mold/mycotoxin development during storage; mathematical modeling, optimization and improvement of classical on-farm in-bin grain drying, storage, chilling and aeration systems; and grain processing byproduct value-added processing and utilization.
