Prior to this position, Dr. Sako was an Engineering Specialist, a Senior Engineering Specialist, and an Aerospace Fellow. Dr. Sako has made signi?cant contributions to the ?elds of structural dynamics, numerical analysis, and time series data analysis. His development of the ?ltering approach used to separate the more rapidly varying wind features from more slowly varying components is used on several launch vehicle programs to develop turbulence forcing functions for atmospheric ?ight loads analysis. Dr. Sako also developed an approach to remove tones from wind tunnel buffet test data; the approach was used, for example, on NASA’s Space Launch System (SLS) program. His developments have also made signi?cant contributions to the assessment of the internal dynamic properties of rocket engines, pogo stability of launch vehicles, and the development of forcing functions for loads analysis. Dr. Sako developed state-of-the-art time series analysis and mode parameter identi?cation tools that have been used to analyze data and identify structural dynamic parameters on numerous operational systems. The time series data analysis tool is used to assess ?ight and ground vibration test data. The mode parameter identi?cation tool is used to extract mode parameters from launch vehicle and satellite mode survey test data, as well as ?ight data. Dr. Sako’s developments are used routinely to assess data from operational launch and space systems. Dr. Sako has published 25 technical papers, and written 100 corporate technical reports. He has taught graduate classes in numerical analysis, engineering mathematics, and signal processing. Dr. Sako has earned numerous awards and letters of commendation, including The Aerospace Corporation’s President’s Award, Division and Group Achievement Awards, and several Program Recognition Awards. Dr. Sako’s B.A. and M.A. degrees are from the University of Hawaii, and his Ph.D. is from UCLA.voir moins
