I am currently seeking a qualified student to begin Fall 2014 with research in the area of:


Quantitative Analysis of Detrital Mineral Data


We are working on a new method for comparing detrital age distributions. We use bootstrap resampling (n = 100, resampled 1000 times) to generate a statistical range of expected variability for small subsets when drawing a sample of ages from large compiled datasets representing hypothesized “source areas” (a Predictive Range). Comparisons of detrital samples to these resampled distributions allow us to identify the age components in the samples that remain unexplained by drawing from the source distribution, as well as quantification of how large the mismatch is.  Comparisons performed based on this method result in a single-value quantitative measure of similarity that has a statistical basis, and provides an assessment of the age components that are responsible for the mismatch.


Beginning fall 2014, I’d like to mentor an M.S.-level graduate student through a project to formalize the statistical algorithm and write a program using the language R.
