I have a variety of technical interests to maximize the capability of existing observational facilities (especially JWST/NIRCam WFSS) to chart the unexplored scientific domains and innovative parameter spaces, specifically in extragalactic astronomy and the high-redshift Universe. I am (co)-leading multiple JWST programs since Cycle-2 (2023) as PIs and co-PIs, totalling more than 1,000 telescope hours. Through the combination of both calibration and scientific observations, I wish to demonstrate the new technical feasibilities and new scientific opportunities to support the research from the broader community of observational astronomy.

Such technical interests have been driving my scientific researches to be highly diverse, and my refereed publications cover the areas from Milky Way star-forming regions (NASA news blog) to the cosmic redshift frontier (ESA news blog). My main research focuses on the spectroscopic census of star-forming galaxies around the Epoch of Reionization, which requires multiple techniques including space-telescope imaging, slit and slitless spectroscopy, radio interferometry, and sometimes the cosmic magnifiers (gravitational lensing). Through the technology development and data exploration, I gain interests in a variety of phenomena and physics, including but not limited to active galactic nuclei (AGN), circumgalactic medium (CGM), chemical abundance, cosmic star formation, cosmic reionization, dust, galaxy evolution, galaxy kinematics, gravitational lensing and microlensing, interstellar medium (ISM), large-scale structures, quasars, quenching, stellar population, submillimeter galaxies, supernovae and transients (in alphabetic order).

I am more than happy to talk with you to discuss new scientific explorations that can capitalize our technologies and data.
