Hello, I'm a Research Scientist at the California Institute of Technology (Caltech) and a Visiting Scholar at the Jet Propulsion Laboratory (JPL). I work on the modeling, analysis, and pipeline development for cosmology and extragalactic background science for the SPHEREx mission, scheduled to launch in early 2025.

My research aims to enhance our understanding of cosmology and extragalactic science questions using data from large-scale structure surveys. My work spans several areas within these themes, including (1) developing novel analysis algorithms to extract information from cosmological surveys, (2) constructing data-informed models to improve cosmological analyses, (3) analyzing existing datasets to derive constraints on cosmological and astrophysical information, (4) modeling foreground and systematic effects for future cosmological surveys, and (5) developing analysis pipelines and designing strategies to mitigate systematics in forthcoming large-scale structure surveys.

Currently, my research is geared toward preparing for the upcoming SPHEREx mission. In particular, I am focused on characterizing the systematic uncertainties in their cosmology pipeline, a critical challenge for one of their main goal of constraining primordial non-Gaussianity using its all-sky galaxy catalog. Additionally, I work on modeling the extragalactic background signal, which SPHEREx will probe with unprecedented high sensitivity and spectral resolution in the near-infrared.

A significant portion of my previous research has centered on "line intensity mapping," which utilizes the full emission field to map large-scale structures, unlike conventional redshift surveys that rely on resolved sources. Specifically, I developed strategies for mitigating foreground interference in line intensity mapping. Another key area of my past work involves studying the extragalactic background light, focusing on contributions from the intra-halo light, the diffuse stellar emission surrounding galaxies.
