Research Overview

My research concerns the low temperature properties of nanoscale structures. In particular, quantum dots and nanoelectromechanical resonators. At low enough temperatures, quantum mechanical phenomena can dominate the behaviour of these structures. I am interested in how this can be exploited to build new solid-state devices to advance computation, metrology, and sensing. I am currently working on techniques to measure nanoscale devices at temperatures below 1 millikelvin.
