Since joining Schlumberger in 1997, David’s career has encompassed a variety of assignments as both an engineer and a manager related to research and development (R&D) and manufacturing of oilfield equipment. In his various roles, David has worked for two different business segments (Drilling & Measurements and Artificial Lift) and six different R&D centers in the U.S., the U.K., and Singapore. He currently serves as the Research Director for Mechanical and Materials Sciences where his group conducts basic and applied research supporting Schlumberger’s business segments.

David's technical expertise is in the general area of machine and system design with an emphasis on solid mechanics and advanced materials. David graduated from the University of Illinois in 1991 with a BS in Aerospace Engineering and received his MS and PhD degrees in Mechanical Engineering and Materials Science from Rice University in 1993 and 1995 respectively. David is a licensed Professional Engineer and a member of the American Society of Mechanical Engineers (ASME) and the Society of Petroleum Engineers (SPE).

David’s professional experience has been primarily focused on engineering and technical management related to new product development. He has lead the development of state-of-the art, technologies for slim-hole rotary steerable drilling tools and electric submersible pumps for extreme high temperature environments as well as advanced materials for zonal isolation and stimulation. This work has allowed David to interact closely with Business Development and Field Operations teams to develop breakthrough technologies for some of the oil and gas industry’s most challenging problems. These projects have received four “Performed by Schlumberger” awards and have been nominated for various industry awards for technical innovation. In addition to R&D, David has a keen interest in operations research and manufacturing technology to enable efficient and cost effective manufacturing operations.

David has authored or co-authored several technical papers for professional journals, industry publications and conference proceedings and has received numerous patents for many of his inventions. He has developed and taught technical courses on machine design for downhole oilfield equipment and has been an invited speaker on the topics of new technology and manufacturing for many professional society and industry events.
