Upon completing his doctorate, in the Spring of 1996, he moved to Los Angeles, California, to join an aerospace materials consulting firm. In the Fall, Olivas was offered a senior research engineer position at the Jet Propulsion Laboratory (JPL), Quality Assurance Section, in Pasadena, California. His research included the development of tools and methodologies for nondestructively evaluating microelectronics and structural materials subjected to space environments. Shortly after, he was promoted to Program Element Manager of the JPL Advanced Interconnect and Manufacturing Assurance Program. This NASA sponsored research effort included scientific investigations aimed at evaluating the reliability and susceptibility of state-of-the-art microelectronics for use in future NASA projects. Additionally, he was the JPL lead for the NASA Safety Reliability and Quality Assurance Nondestructive Evaluation (NDE) program and was the sole NASA representative investigating applications of NDE to microelectronics applications. Through his career, he has authored and presented numerous papers at technical conferences and in scientific journals and is principal developer of seven inventions.
