Dr. Morris' research focuses on devising and developing new engineering technologies for the food production and packaging industries. In conjunction with the Beckman Center for Advanced Research, using ultrasound and optically computed tomography, the University of Illinois Packaging Laboratory has developed experimental technologies that are being used to evaluate defects in package seals and structures for use in preventing post-processing contamination. Current technology has been developed that can image defects as small as 0.00025" in opaque material, with higher resolution available at higher frequencies. Further research is aimed at improving signal processing capabilities as well as investigating the nanoscale transport of contaminants into food package structures. Other research is directed at packaging operations in small to medium sized companies that are often pressed to increase capacity without having sufficient capital to do so. Using computer modeling and simulation, the University of Illinois Packaging Laboratory has demonstrated that it is both feasible and profitable to implement operational modifications to increase productivity. In a major food company's packaging plant, analysis and restructuring of machine operation protocols resulted in a $1.6 million per year increase in production, with no additional capital investment. Using cryptographic techniques as well as advanced optical information technologies, preliminary investigations are being conducted into the feasibility of providing high security verification markings for structures such as food and pharmaceutical packages. This research is directed at determining whether or not it is both possible and practical to include information verifying shipment source and contents during distribution.
