My research focuses on understanding galaxy formation and evolution across a range of physical scales. I use spectroscopy and full-spectrum stellar population modelling to characterize the stellar initial mass function (IMF), elemental abundances, and formation histories of galaxies, with much of my recent work focused on massive, quiescent galaxies. I work extensively with JWST observations and am involved in collaborations including SUSPENSE and IMFERNO, which use resolved and integrated spectroscopy to study the assembly and evolution of distant galaxies. I am also leading a JWST Cycle 5 NIRCam imaging program investigating the role of mergers in galaxy evolution. Additionally, I make use of large spectroscopic surveys, such as LEGA-C and SDSS. I am broadly interested in developing and applying observational and modelling techniques that connect the detailed properties of stellar populations to the physical processes driving galaxy evolution across cosmic time.

Tri Nguyen studies the distribution of dark matter on sub-galactic scales, using the internal kinematics of Local Group dwarf galaxies and perturbations in cold stellar streams to test dark matter models. He develops simulation-based inference and geometric deep learning methods to extract these constraints from next-generation survey data such as Rubin/LSST.

I am a Postdoctoral Fellow at the University of Toronto (David A. Dunlap Department of Astronomy & Astrophysics), and my passion lies in gravitational lensing — nature’s own cosmic magnifying glass. I focus on massive galaxy clusters, which bend and amplify the light of distant background objects, turning them into powerful natural telescopes. Through this lens — quite literally — I investigate how matter is distributed within these colossal structures, and push even further by testing different dark matter candidate models to understand what these clusters are actually made of.
One of the most exciting aspects of my work is hunting for individual stars at cosmological distances, objects so remote that they would normally be completely invisible to us, but which gravitational lensing brings briefly into reach. I combine photometric and spectroscopic analysis across the optical and infrared, making the most of the incredible capabilities of HST and JWST to catch and characterize these rare, fleeting detections.
My scientific curiosity doesn’t stop there. I have dabbled in CMB science using data from the Planck mission, exploring machine learning approaches to galaxy cluster detection, and I keep a keen eye on developments in cosmology and multi-messenger astronomy more broadly. I genuinely enjoy stepping outside my comfort zone and learning new things!
