My research focuses on observations of the diffuse circumgalactic medium (CGM) — the outermost envelopes of galaxies. I seek to better understand the dynamical state of the CGM, and its connection to the star-formation/AGN activities of galaxies and the cosmic baryon cycle in general. My work heavily relies on data obtained by wide-field, integral-field spectrographs (e.g., VLT/MUSE), together with photometric and spectroscopic data from several different telescope such as the Hubble Space Telescope and the Magellan Telescopes.
I also have extensive experience in lens modeling of strong gravitational lensing clusters, with both parametric and free-form methods.
