Dr. Glaser is the lead scientist for the United States Environmental Protection Agency, National Risk Management Research Laboratory\'s (NRMRL) Biotechnology Research Program. His research is focused on the evaluation of technology and products to meet the criteria of sustainability. One aspect of sustainability assessment that he followed is the application of these criteria to transgenic crops. These crops can be viewed as environmental assets since they improvement to human health by avoiding the application of toxic pesticides for the grower. Hence, it is important to prolong the useful lifetime of the transgenic crop. The major threat to the longevity of these crops is the evolution of resistance in the pest population to the crop protectants. He designed a series of expert workshops and other information gathering means to assist the development of the analytical framework for the resistance management of transgenic crops. The NRMRL Biotechnology Program evaluated remote sensing for crop monitoring, resistance model testing & development, resistance detection methodology standardization, development of non-target effects field scale protocols, pollen effects management, and toxin testing standardization. A monitoring program capable of detecting pest damage in GM maize plantings has been completed for implementation by the EPA. A process patent was awarded for this technology. This research has continued the use of remotely sensed information to understand land-use change, ecological function, and processes within watersheds. Application of this inquiry to the bioconversion of corn starch to ethanol was conducted for an Illinois conversion facility and used to identify land-use change and potential ecological function for the operation. Lead scientist for the EPA Biosystems Research Program design and conducting research inquiry into bioremediation. As research leader in fungal technology for the treatment of soils and solids contaminated with hazardous waste, he received a joint recognition award from USDA and USEPA for the development of a field-scale technology based on the use of a lignin-degrading fungus for the treatment of hazardous chemicals polluting contaminated soil. He has led research teams to develop unique bench-scale testing facilities for the evaluation of bioslurry and compost treatments of hazardous waste contaminated soils and to permit evaluation of the two technologies using contaminated field materials. Participated in the EPA research effort applied to the EXXON Valdez oil spill in Prince William Sound, Alaska and was recognized by the award of the EPA Gold Medal. His recent research effort that focuses on the environmental degradation of polymers was published as a book chapter.
