Dave has a BS in Chemical Engineering from Texas A&M University, a PhD in Chemical Engineering from the University of California at Berkeley, and is a registered Professional Engineer in Colorado.  He has 20 years of experience in process engineering, techno-economic analysis, and scientific computing, spanning the renewable fuels, petrochemical, and semiconductor industries. His primary background is chemical process simulation, with related experience in conceptual design and front-end engineering activities for new chemical and biochemical processes. As the owner and principal engineer of DWH Process Consulting LLC, Dr. Humbird provides process design and engineering services to startups and companies with limited staff. Target industries include Renewable Fuels and Chemicals, Biorefining, and Synthetic Biology. Typical projects comprise a preliminary estimate of process ROI, based on Client, literature, or theoretical yields, original simulations in Aspen Plus, and preliminary CAPEX estimates in Aspen Capital Cost Estimator. Dave is also a frequent user and advocate of Aspen Custom Modeler, for first-principles design of individual unit operations, particularly bioreactors.  Contact Dave
