A detail oriented and science minded chemical engineer by trade, I excel at process optimization, thinking outside of the box and coming up with creative ways to solve problems, save energy and increase cash flow. I have experience in mineral & metal processing & refining, bio-refining and bio-products, corrosion analysis, water treatment and waste water handling. I have an extensive analysis skill set that includes concrete statistical knowledge as well as formal education on experimental design & stimulus/response screening & optimization. I have an entrepreneurial background, and perform well in small, highly robust teams as well as individually or part of a larger group. Perhaps most importantly however, I have proven experience transforming these skills into dollars - as shown by my project portfolio, containing new product lines, reduced operating expenses, extensive research results and extensive hard payback dollars generated.
