From studies of solubility and divers breathing helium, to DOGS, then NCAR and NASA


Dr. Peter Hildebrand: "How did I get to where I now find myself? Holy Cow! It has been an eventful path, with role models, mentors, a few fumbles, and a lot of love for the study of Mother Nature. At Chicago, learning about how a bubble chamber works; seeing Sputnick go overhead on that first day; learning about the course for crazies: weather modification, which then spurred me on to "dig and discover". Realizing we could actually build the most advanced weather radar ... perhaps ever ... and then doing it. And finally coming to participate in the penultimate set of space observations of Earth. What a ride! What is next?"

My Story: A Tale of Three Continents


In this talk, Dr. Lau tells the story of how world events, and the culture and education systems of three major continents, Europe, Asia and North America, shaped his upbringing, career goals and work ethics. He talks about his experience as a kid growing up under a colonial education system with strong Chinese cultural influence, his aspirations to pursue a career in physics, and how he accidentally entered the field of atmospheric sciences in the US. Then he discusses the evolution of NASA from a pure science (as far as he is concerned) to a mission oriented agency from the early 1980’s to present, with respect to his early work on air-sea interaction modeling (his PhD thesis), monsoon cold surges, ENSO instability; how he rediscovered the 40-50 day oscillations (a.k.a., the MJO) and the Pacific heating dipole from satellite observations; involvement in the formulation of the TRMM; how to make a time series sing; participation in TOGA-COARE and leading the SCSMEX monsoon experiments, and more recently, circumstances leading to the formulation of the “Elevated Heat Pump” (EHP) hypothesis on aerosol-monsoon climate interactions, and the Ying-Yang of floods and droughts occurrence under climate change. Finally, he talks about his decisions to take on positions as the Branch Head (now Lab Chief) in 1991, and then Chief of the Laboratory for Atmospheres (now Deputy Director for Atmospheres) in 2003, which marked two major bifurcations in his professional career. Dr. Lau has found the right balance and enjoyed his roles in both management and in science research. He is fortunate to have the diverse expertise, and the best and brightest minds around at NASA to bounce off new ideas on science, projects and missions.
