Mr. Graham is a Project Engineer for The University of Tulsa (TU) serving primarily the TU Fluid Flow Projects (TUFFP) and TU Paraffin Deposition Projects (TUPDP) consortia within the Petroleum Engineering Department. This consortium consists of sixteen international oil companies and focuses it’s studies on fluid flow and paraffin deposition. His responsibilities include working with Master and Ph.D. students to develop innovative measurement systems and sensors; plus teach and transfer practical instrumentation and control knowledge to students. He has an Associates Degree in Electrical/Electronics and has over 23 years of experience in the application and development of instrumentation devices and systems. He is currently working on his Bachelors in Political Science. Prior to coming to TU, Scott was the Program Coordinator for the Electrical/Electronic program of study at Oklahoma State University (OSU) – Okmulgee. In addition to the administrative responsibilities of his position, he served as the advisor to the ISA student section and taught the Process Measurement and Control classes. He served in that position for five years.

Scott began his career working as a roustabout for Conoco NGP in Carlsbad, New Mexico. Later as an instrument technician Scott designed and installed automation systems for gas processing plants. He also performed new electrical construction and assisted in putting together an electrical/instrumentation training program classes for Conoco's associate engineers in New Mexico and West Texas.

In 1992 after working for Conoco and gaining experience elsewhere, his career lead him to operate his own company based in Broken Arrow, Oklahoma. Through Panel-Tek Inc., he designed, manufactured, and marketed chemical injection equipment, and electronic controls for the petroleum industry. From this work he holds several patents related to measurement of crude oil and related processes. The products produced included such items temperature and pressure measurement devices, flow computers, and data acquisition equipment. In 1997 Emerson Electric purchased Panel-Tek where he stayed on as Operation Manager for two years.

Scott enjoys working with students to help them to develop and master the technical skills needed to function in today’s marketplace.
