# overview
Dr. Dara W. Childs, P.E. was Director of the Turbomachinery Laboratory from 1984 to 2018 and held the Leland T. Jordan Chair in Mechanical Engineering at Texas A&M University. He received B.S. and M.S. degrees (Civil Engineering, 1961, 1962) from Oklahoma State University, and his Ph.D. (Engineering Mechanics, 1968) from the University of Texas. He was named ASME Fellow Member in 1990 and received ASMEs Henry R. Worthington Medal in 1991. Dr. Childs' expertise is in dynamics and vibrations, with an emphasis in rotordynamics. He has conducted research and engineering projects for NASA, DOD, and private firms. Current research includes high-pressure testing honeycomb and hole-pattern gas damper seals; testing high-pressure laminar oil seals; force measurements in magnetic bearings using fiber-optic strain gauges. Dr. Childs has authored numerous reviewed publications related to rotordynamics and vibrations, and the book, Turbomachinery Rotordynamics. He is presently completing a new dynamics book entitled, Dynamics in Engineering Practice.
