Series expansions in lattice statistical mechanics

Finite lattice method: Initial proof of validity, various algorithmic improvements, extensive applications, overall review [Nucl Phys B, (Proc Supp), 47, 180-187 (1996)]. (MORE).
Contributed to implementation of corner-transfer-matrix method of series expansions.

Inversions of CO2

Development of mass-balance inversion technique.
Development of Bayesian synthesis technique that became de facto standard for CO2 inversions.
Wrote first book on inversions of trace gas concentrations: Inverse Problems in Atmospheric Constituent Transport (CUP, 2002).
Head of modellng group in CSIRO integrated program of CO₂ modelling and measurement that formed the basis of Federation Fellowship offer to Roger Francey (Offer subsequently declined by CSIRO).

Projections of future CO2

Systematic uncertainty analysis through Bayesian calibration.
Coordinated group performing projections of CO2 as input to IPCC report in Radiative Forcing of Climate Change.
Methodological developments on the analysis of the Brazilian Proposal as part of the Experts Group convened by SBSTA (Subsidiary Body for Scientific and Technical Advice) under the Framework Convention on Climate Change.

Other
