Research Interests
My research interests focus on time-domain astronomy and transient phenomena in the universe. I am currently using radio and X-ray observations to study transient sources such as supernovae, tidal disruption events, active galactic nuclei.

Characterizing Transient Ultraluminous X-ray Sources
We serendipitously found a new transient ultraluminous X-ray source (ULX) in the Andromeda Galaxy (M31). Exploded in 2021, we characterized its spectral and luminosity evolution using multi-epoch X-ray observations from Swift X-ray Telescope and Chandra X-ray Observatory. This discovery expands the small population of known transient ULXs in M31 and highlights the value of regular X-ray monitoring of nearby galaxies. [Read the paper]
Radio Variability Search in Poststarburst (PSB) Galaxies
We are investigating radio variability in a sample of 5039 post-starburst galaxies (see Figure 1 of K. D. French et al. 2023) using observations from Epochs 1–4.1 of the Very Large Array Sky Survey (VLASS). By identifying variable sources within this population, we aim to better understand the physical mechanisms driving their activity: tidal disruption events, active galactic nuclei, or other phenomena?
X-ray Supernova Analysis Pipeline (XSNAP)
XSNAP is an open-source Python-based pipeline that streamlines every step of X-ray supernova data reduction and analysis, from raw event processing and spectral fitting to deriving CSM density profiles and progenitor star's mass loss rates. Pipeline is available in GitHub, PyPI, and a dedicated website. XSNAP and its application to SN 2024ggi are described in this paper.
