David began his career in 1980 with the Chemicals Research Division of Conoco at Ponca City, Oklahoma.He developed an enduring interest in mixing and agitation while performing development work with VCM and PVC processes operated by Conoco Chemicals.In 1984, he switched research focus to the production and use of high purity aluminas made as a coproduct from the Ziegler alcohol process.Following the DuPont purchase of Conoco, Vista Chemical Company was formed from Conoco's chemical assets and David moved with the R&D Department of the new company to Austin, TX, in 1989. Vista Chemical Company became CONDEA Vista in 1994 after its purchase by the German conglomerate, RWE-DEA.In 1995, David moved to Lake Charles, Louisiana, as part of a pioneering group of researchers that provided direct technical support to manufacturing processes located there and served as a conduit to rapidly implement R&D advances in the plant.The success of this group led to a similar assignment at the alcohol and alumina plant in Brunsbuttel, Germany. From 1997 to 2000, David led a team of scientists in optimizing numerous production processes and trained them in the field of technology support.He returned to Lake Charles in 2000.The CONDEA chemicals business was sold to Sasol, Ltd., in 2001, and CONDEA Vista became Sasol North America.Currently, David is responsible for worldwide technology and customer support of the high purity alumina business for North American products.He also is a global agitation and mixing consultant within Sasol.

David is a co-inventor on four U.S. Patents.He has four publications in reviewed journals.He organized and co-chaired an AIChE session on industrial mixing.Recently, he taught portions of an Industrial Chemistry graduate class for chemistry students at McNeese State University.He is a member of the American Institute of Chemical Engineers and the American Chemical Society.David resides in Lake Charles, Louisiana.
