Research
Statement of Research:
I'm working on reconstructions of the probability distribution of the climate of the past, conditioned on observational proxy data, such as tree ring width.
Reconstructions by Bayesian hierarchical modeling allows for the incorporation of nonlinear proxy-climte relationships, as well as for the natural integration of the many sources of model and data uncertainty.
This work is being carried out through the U of A Laboratory of Tree Ring Research. My advisor is Mike Evans (now at U. Maryland Dept. of Geology).
