I joined the University of Nottingham Malaysia in 2013 and was promoted to Associate Professor in 2017. This followed time at the University of Cambridge where I completed my PhD (2008-2012) and a short post-doctoral appointment (2012-2013). My undergraduate studies were at the University of Leeds (2003-2006) and before starting my PhD research I worked at the Bermuda Institute of Ocean Sciences (2006-2008).
I am Course Manager and Admissions Tutor for our BSc Environmental Science.
I currently convene, and teach all or much of, the following modules: Dissertation in Environmental Science, Global Environmental Change: Part 1 and Part 2, and Environmental Modelling. I also teach parts of Global Environmental Processes.
I am interested in various aspects of atmospheric and climate science, often in the context of tropical Asia. My research mainly involves a combination of computer models and observational datasets.
A recent focus has been on the rapid long-range transport of atmospheric pollution from East Asia towards the tropics (paper). This mechanism appears to have important implications for regional air quality (paper) and for the stratospheric ozone layer (paper).
I am also closely involved, now as Director, with Mindset - UNMC's Interdisciplinary Centre for Environmental Studies. One aspect of this research has concentrated on how the public views "haze" episodes (paper) and urban air pollution (paper).
Past research considered emissions of biogenic trace gases from the oceans in Southeast Asia (paper) and their subsequent transport towards the stratosphere (paper) where they can influence ozone layer chemistry.
