Research Interests

My research has focused on several key questions:

  • How do the compositions (i.e., dust, gas, stars) of the first galaxies compare to those of local galaxies, and is there a continuous evolution of these properties?
  • What are the relative effects of mergers, in- and outflows, and secular accretion on the baryon cycle, gas content, and star formation of these galaxies?
  • How can we improve current models and analysis techniques to maximize the yield of the relatively limited observations of high-redshift galaxies?

To tackle these open issues, I conduct observations of z>4 galaxies with current instruments (e.g., ALMA, JVLA), characterize their kinematics with tilted ring models and morpho-kinematic analysis, and derive gas masses through SED models and line tracers.

Galaxies in the Infant Universe Were Surprisingly Mature

Oct 27, 2020

Massive galaxies were already much more mature in the early universe than previously expected. This was shown by an international team of astronomers—including researchers from the Kavli Institute for Cosmology (KICC) and the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) — who studied 118 distant galaxies with the Atacama Large Millimeter/submillimeter Array (ALMA).
