Researcher's projects

I am an applied mathematician and physical chemist with broad research expertise in nonlinear and complex dynamical systems. 

Current research is on the origins of life. In a series of papers we have elucidated the role of hydrogen peroxide in mediating the RNA world, proto-metabolic systems and the development of biological homochirality.

Anomalous thermal fluctuation distribution sustains proto-metabolic cycles and biomolecule synthesis
Physical Chemistry Chemical Physics, January 2020, DOI: 10.1039/c9cp05756k

In this paper we report an extraordinary fluctuation distribution of time-varying states in stochastic reactive media that may reflect transient non-Boltzmann populations of internal quantized modes. This result has far-reaching implications with respect to the physical chemistry of complex nonequilibrium molecular systems. It says that such systems must be dynamically far from equilibrium in order to sustain net synthetic capability and chemical evolution.

My ARC Future Fellowship FT0991007 project involed a suite of applications of thermochemical instabilities and oscillations, and second law thermodynamic analysis of such systems. 

The next 50 years will be the era during which the world's fuels must be decarbonised. Endex thermoreactive principles, which I co-invented in the mid 1990s, are providing a novel technology for separating carbon from fuels and flue gases. I am developing a suite of Endex decarbonation technologies in collaboration with an industry partner, Calix Ltd, and with collaborators from Imperial College London, and the FP7 ASCENT Program. 

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. My research is elucidating this mechanism.

Oscillatory thermal instability can also initiate thermal explosions. 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 found that oscillatory thermal instability is the initiator of thermal runaway in liquid peroxides and also was the primary cause of the Bhopal disaster.
