He completed a master’s degree in physics with Dan Walls at Auckland University in 1995, and a PhD with Peter Knight at Imperial College, London, in 1998. While at Auckland he was introduced to classical continuous measurement theory by Sze Tan, and the recently developed field of quantum continuous measurement by Howard Wiseman. He continued to work on this subject during his PhD, and then joined Los Alamos National Laboratory to work on quantum feedback control with Salman Habib in a collaboration with Hideo Mabuchi. His work currently focuses on Quantum Measurement, Feedback Control, and Quantum Nano-Electro-Mechanical Systems.
