Project U-Pb and Trace Elements in Apatite

Principal Investigator:

I am working to measure high precision (better than 5% uncertainties) 206Pb/238U ages on natural apatites. Trace element concentrations in apatites include Li, Cl, S, F, Mg, Fe, Sc, Y, REE, Hf, Th, and U, and are reproducible to better than 5% (1sigma). I have been working with several groups to analyze natural apatites, as well as Jonathan Payne's group analyzing trace elements in conodonts.

Project Family study of emotional and cognitive brain function in first degree relatives of depressed probands, Stanford University and Sydney Medical School (5/15/2014)

Principal Investigator:

Data acquisition for 101 relatives and 101 non-relative matched controls is complete. Opportunities exist for graduate students and post-doctoral fellows to analyze the data in new ways, for publication.
This study was funded by the Australian Research Council from 2007-13. The aims of the study were as follows:
The aim of this project is to understand vulnerability for depression in individuals. By understanding how depression develops, we can develop prevention and early intervention strategies.
