Projects I'm currently involved in:
SDSS-III: Sloan Digital Sky Survey III
APOGEE: Apache Point Observatory Galactic Evolution Experiment
The Schiavon models for single stellar populations. Send me an email if you
want me to generate customized models for you.
EZ_Ages: A code devloped by Jenny Graves from Lick Observatory, that uses my models
to determine the light-weighted ages and abundances of Fe, Mg, C, N, and Ca for stars in
early-type galaxies from absorption lines in their integrated spectra.
Integrated spectra of Galactic globular clusters You can download the spectra
from that website. Send me an email in case you want calibrated Lick indices
measured in the cluster spectra.
