  • Houston

Dr. Eason has a specialized background in the areas of mechanical vibrations, dynamics, and finite element analysis, in addition to hands-on experience in oil and gas drilling and manufacturing. Within his doctoral research, Dr. Eason used numerical, experimental, and analytical methods to identify the complex non-linear interactions in a structural vibration absorber. He also developed a computational method used to increase the efficiency of analyzing the global dynamic behavior of mechanical systems. Dr. Eason’s Master’s degree research identified and quantified measurement errors resulting from the presence of higher harmonics in the response of an atomic force microscope probe.

Dr. Eason’s oil and gas experience includes roles in field operations and business development. Prior to his graduate studies, Dr. Eason worked as a Logging While Drilling (LWD) Field Engineer on both land and offshore drilling rigs. He was responsible for monitoring and interpreting real-time drilling data from surface and downhole equipment. Dr. Eason was also a founding member of FracEnsure, a start-up company specializing in uniquely identifiable nano-particles used for long-term, long-distance tracking of hydraulic fracture fluids. His specific contributions included constructing a field implementation strategy which included an assessment of material injection and logistics as well as developing the business model and marketing materials. He has also contributed to the technical development of a start-up company specializing in produced water filtration and maintains an active role on the board of advisors for the Global Energy Safety Institute.

In his work at an advanced prototyping facility, Dr. Eason executed all stages of prototype design from initial concept to finished product. He is proficient in computer aided design (CAD) and has hands-on experience in manual and computer-controlled (CNC) precision manufacturing including milling, turning, and plasma cutting.
