Born in Northern Ireland and educated at Oxford University, Christopher Earls Brennen was a member of the Mechanical Engineering Faculty at the California Institute of Technology for over 40 years and retired as the Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering in 2005. At various times he also served as Master of Student Houses, Dean of Students, Executive Officer (Department Chair) of Mechanical Engineering and Vice-President for Student Affairs at Caltech. As a teacher he was the recipient of a number of teaching awards including the prestigious Richard Feynman Prize. He is the author of  over 250 scientific papers and of three sole-authored books, “Hydrodynamics of Pumps”,  “Cavitation and Bubble Dynamics”, and  “Fundamentals of Multiphase Flow”, all currently published by Cambridge University Press. The first has also been translated into Japanese, Chinese and Farsi and the second into Chinese. He is also the author of popular interent guides to the sport of canyoneering. Brennen has also served as a consultant to numerous private companies and government agencies including the Nuclear Regulatory Commission, Brookhaven National Laboratory, Lawrence Livermore Laboratory, and Batelle (Hanford) among many others.
