I have 50 years of experience, and specialize in the field of chemistry with specific knowledge in the areas of phosphorus chemistry, organophosphorus-containing catalysts and toxicity of organophosphorus compounds. I have published on such topics as organophosphorus chemistry, organophosphorus catalysts and biodiesel and drying oil production from plant oils. After 50 years I continue to have a remarkably inventive (over a dozen patents and a national prize for inventiveness) and productive (over 420 publications and 5 books) career.
