David Dankworth, PhD, is distinguished scientific advisor at Exxon Mobil, and visiting research scholar at Princeton University. Dave is a chemical engineer trained at Rice University (BS 1986), University of Cambridge (CPGS 87, Churchill Scholar), and Princeton University (PhD 91, Hertz Fellow). His dissertation and early industrial work focused on hydrodynamics, design, and behavior of multiphase chemical reactor systems. He joined Exxon in 1990, initially working on a number of reactor scale up and design projects related to new lubricant additive and chemical products. He also was involved in development of reactor hardware enabling the economic production of ultra-low sulfur fuels, which was deployed commercially throughout the 1990's and 2000's. He is the inventor on over 20 U.S. and international patents.

Currently, David manages downstream process engineering at ExxonMobil, which provides technical expertise supporting operations and project development at ExxonMobil refineries around the world. Additionally, in his management career, David has led a range of global technology groups within Exxon and ExxonMobil, including heat transfer, combustion, energy conservation, catalytic cracking, and hydroprocessing. He also has played roles in operations as technical manager of the Ingolstadt refinery in Germany, and managed regional engineering support for both Europe and Canada. He has been in his current role as global refinery process engineering manager since 2009.

Dave's continuing interests are in the areas of chemical reactor engineering, process intensification, global Energy supply, corporate and industry strategy, and technical organization effectiveness. Dave currently lives in Great Falls, Virginia, is married to Pamela Williams, and has three sons. Dave enjoys backpacking, and recently accompanied a crew of Boy Scouts on a two-week trek at Philmont Ranch in New Mexico.
