Positions

  • My general interests lie in the modelling of the chemistry and transport of trace gases in the troposphere using state-of-the-art atmospheric models.
  • Recently, I have been involved in the attribution studies of sources and sinks to greenhouse gases using forward and inverse modelling techniques.

Overview

OverviewText1

  • Steven studied for a B.Sc (Hons) in Physical Chemistry from 1991 to 1996 from the University of Malawi (Chancellor College). He then moved to Cambridge University, Sidney Sussex College, where he studied for a PhD in Atmospheric Chemistry under the supervision of Professor Roderic Jones from 1997 to 2000. His thesis was titled ~Studies of Atmospheric Surface Ozone using a Novel Solid-State Sensor~. After this he moved to Imperial College London where he worked with Dr Michael Jenkin. His research was in the development and application of models of tropospheric chemistry using both highly detailed and reduced chemistry schemes. In 2006 Steven moved to Bristol University's Atmospheric Chemistry Research Group where he was involved in the the development and implementation of Secondary Organic Aerosol (SOA) schemes in a global (3-D) model (STOCHEM). Recently Steven worked in the School of Earth, Atmospheric and Environmental Sciences (SEAES) at the University of Manchester where he has was involved with the development and implementation of a reduced atmospheric chemistry scheme in the chemistry version of the Weather Research Forecasting (WRF) - WRF-Chem. In August 2012, Steven moved to Australia where he is currently working with Prof Peter Rayner as a greenhouse gas inverse modeller in Melbourne University's School of Earth Sciences.

Supervision Statement

  • I develop and run state-of-the-art atmospheric transport models that simulate the evolution of trace gases ranging from pollutants such as ozone and oxidants (VOCs) to greenhouse gases such as CO2 and CH4 in the lower atmosphere. I am also interested in the evolution of aerosols and their role in regulating climate. I also use atmospheric inverse modelling techniques to attribute sources and sinks to greenhouse gases.
