Research
Symbiotic stars, stellar outbursts, and the time-domain sky.
My research focuses on how interacting binary systems change during outbursts. I combine long-term spectroscopic monitoring, photometric observations, and multi-wavelength analysis to study their evolution.
Symbiotic stars & interacting binaries
I study hot- and cool-type classical symbiotic outbursts, including YY Her, CM Aql, and TCP J18224935−2408280. Monitoring across orbital phases helps trace the evolution of the hot and cool components.
Novae & time-domain astrophysics
I follow the spectral and photometric evolution of nova eruptions, from the fast nova V1674 Herculis to recurrent systems such as RS Ophiuchi and M31N 2008-12a.
Multi-wavelength analysis & research software
I connect optical and X-ray observations, model spectral energy distributions and continuum components, and develop tools for spectroscopic reduction. My semi-automated HFOSC pipeline has been used in five published papers. My interests also include machine learning for classifying stellar outbursts and astronomical light curves.
