We study the evolution of the earliest stars and galaxies that formed soon after the Big Bang by measuring the chemical abundances of old, metal poor stars and also simulating the formation process of galaxies like the Milky Way.
I am an Assistant Professor in the
at the Massachusetts Institute of Technology (MIT), Cambridge, MA, USA.
I am also a member of the MIT Kavli Institute for Astrophysics and Space Research.
My research interest broadly cover the early universe, the beginning of the chemical evolution and the formation of the first stars and galaxies. There are two major topics.
Stellar Archaeology: the most metal-poor stars, chemical evolution of the Milky Way and dwarf galaxies, stellar kinematics and galactic structure, supernova nucleosynthesis and neutron-capture processes, nuclear astrophysics, stellar evolution, stellar abundances, spectroscopic observations and analyses
Near-field cosmology: The first stars, early star and galaxy formation, galaxy assembly on small scales, the formation of the Galactic halo, the age of the Universe
For my work, I go observing with the 6.5m Magellan telescopes in Chile several times per year.
