I'm an Astronomy graduate student at Columbia University since 2019. I am also supported by the Doctoral Student Fellowships at the American Museum of Natural History since the Fall of 2021. I spend half of my time on obtaining stellar ages from large stars surveys (e.g. Kepler, TESS, APOGEE, LAMOST etc.) with a focus on gyrochronology calibration and the other half on Galactic Archaeology.
My work focuses on obtaining stellar ages through gyrochronology and spectroscopy. In particular, I have dedicated a lot of my time calibrating gyrochronology relations for low-mass old stars.
Stellar age catalogs I created that are publicly accessible:
Gyro-Kinematic ages (29,949 Kepler ages; available here): We combined kinematic properties (verticle velocity), temperature, magnitude from Gaia, and rotation periods from Kepler to estimate gyro-kinematic ages.
Spectroscopic ages and red clump membership (64,317 APOGEE ages: available here):
We used The Cannon) to obtain stellar ages and red clump membership from APOGEE spectra. These stellar ages are then used to study the properties of the high- and low-α disks.
Recently, my work in galactic archaeology has been on analyzing simulations or comparing simulations to Milky Way data in order to understand the formation history of our own Galaxy. I mainly focus on the importance of radial migration and obtaining birth radii for stars.
