Dr Christie studied at UMIST in Manchester, obtaining his PhD in optical sensor technology in 1990.  He then spent 15 years as a research fellow, gaining experience in associated techniques (lasers, electronics, computing). Having a keen interest in aviation, he also obtained a private pilot’s licence. In 2005, he joined Dr Bennett at the University of Manchester in studying dispersion of pollution from commercial aircraft.

He moved to CATE with Dr Bennett in 2007 and has since worked on many aspects of aviation and the environment. In particular, he has worked closely with our European colleagues in the ECATS network.
