Oscar de Santiago

Oscar came from Queretaro, Mexico, and obtained his MS and PhD degrees at Texas A&M. Oscar worked on developing on-site parameter identification methods and applying them to extract force coefficients from fluid film bearings and SFDs.

Oscar is a happy father and a loving husband. The picture shows him with his women: Adriana and Adrianita.

Thomas Soulas

After receiving his engineering degree in France, Thomas came to Texas A&M University in 2000 to work with Dr. San Andres on seal and process fluid bearings analysis, in partnership with the French spacecraft engine manufacturer Snecma. His experience in College Station was most rewarding. Thomas obtained his Master of Science degree in Mechanical Engineering in 2001, Thomas started as a Rotor Dynamics Engineer at Dresser-Rand, in Olean, NY, in 2002. In 2004, he was appointed Supervisor of the Rotor Dynamics Group at Dresser-Rand, a world leader in energy solutions for the oil, gas and chemical industries. His parents, brother and sister live in Perpignan, in the South of France.

Miller Robison

Originally from the arid plains of Texas, moved to sunny California to work in Solar Turbines and Rocketdyne. Back at Solar in San Diego, Miller plays with lots of gas turbines, name the size! Miller is the tallest boy in the picture.
