Louis J. DeFilippi, Ph.D.


Dr. DeFilippi performs investigations and analyses from a chemistry, biochemistry and microbiology standpoint. He often combines these scientific approaches and analyses with an understanding of OSHA, EPA and USDA regulations, as well as environmental processes, to draw his conclusions. Dr. DeFilippi specializes in a number of diverse areas, including regulatory compliance, patent infringement, safe operation of chemical, biochemical (enzymatic) and microbiological (fermentative) process and ammonia refrigeration, groundwater contamination and bioremediation. He is experienced in worker safety, accident prevention, and training on an industrial scale. He is skilled in laboratory research, analysis, measurements and data workup.
