Christina Williamson, nano-particles instruments

Christina Williamson has exhibited sustained scientific and engineering excellence while passionately pursuing a scientific vision involving improving, modifying, and calibrating a set of unique instruments to measure the size and number of newly formed atmospheric nano-particles. She is operating these instruments during a set of challenging, global-scale airborne measurements to produce a unique dataset that maps out regions of new particle formation in the remote atmosphere, and using these observations to challenge and improve the global models that simulate important but uncertain climate processes. She has seen this multi-year effort through instrument development and testing, four around-the-world measurement campaigns, and the analysis and publication of results. Additionally, she has served as a vocal advocate to the public and a range of scientific communities, maintaining and contributing to blogs, a twitter feed, and presenting at numerous conferences.
