Biographical Info
Research
I am interested in understanding how our Galaxy formed and evolved by analyzing the chemical abundance patterns of stellar populations across the Milky Way. I primarily use data from the Apache Point Observatory Galactic Evolution Experiment (APOGEE).
I completed my B.A. in astronomy and physics in 2013 at the University of Virginia where I worked with Steve Majewski on SDSS APOGEE observations of the Sagittarius dwarf galaxy (Sgr).
My work with APOGEE carried over into graduate school at NMSU where I work with Jon Holtzman on improvements to the APOGEE data reduction pipeline, including the characterization of neutron-capture element lines in the APOGEE spectral region. I have published work on the detailed chemical abundance patterns of Sgr, and am currently working on studying the chemical abundance patterns of the Milky Way, with a focus on stellar ages from carbon and nitrogen abundances.
