Current research

If you are interested in a PhD project on the role of fire in global carbon cycle regulation or new technologies for CO2 separation, and if you have an Hons I degree in applied maths, physical chemistry, chemical engineering or equivalent, you are welcome to contact me or drop in to JD #27 room 1192 for a chat. 

Project I: New Endex technologies for carbon management.

The next 50 years will be the era during which the world's fuels and emissions must be decarbonised. Endex thermoreactive principles [1] underpin new high efficiency systems for separating carbon from fuels and flue gases. In collaboration with Imperial College London, the University of Leeds, CanMet Energy, and an industry partner, I am developing a suite of Endex carbon capture technologies.

Project II: The CharXive Archives and the role of fire in global carbon cycles.

Endex principles also underpin carbon capture from the atmosphere and have been used by nature for millions of years: the mechanism behind thermal decomposition of biomass is an Endex thermochemical oscillator that governs the distribution of carbon between the global solid black carbon reservoir and the atmospheric CO2 reservoir. This research aims to elucidate this mechanism.

Project III: Non-classical thermal ignition.

A grave threat to security is the use of liquid peroxide bombs by terrorists, and it seems grimly inevitable that their use as mass murder weapons will increase. My research on Endex systems has led to the finding that oscillatory thermal instability is the initiator of thermal runaway in liquid peroxides and also was the primary cause of the Bhopal disaster.
