I'm currently a PhD student at the MIT Kavli Institute for Astrophysics and Space Research, advised by Prof. Kiyoshi Masui. My research mainly focuses on using radio telescopes to study the evolution of the universe. Here are the research areas and science questions that I think about:

Recent data from radio cosmology experiments can help answer these questions. Neutral hydrogen, the most abundant element in the universe, emits radio waves with a wavelength of 21 cm. This 21-cm signal carries important information on the universe's expansion history and is highly sensitive to dark energy.  However, the foreground radio emissions from the Milky Way are orders of magnitude brighter than the 21-cm signal, making its detection difficult. I have developed a new class of foreground removal algorithm called Hybrid Foreground Residual Subtraction (HyFoReS) to overcome this challenge (arXiv:2203.07184) and have demonstrated the effectiveness of the algorithm in both simulations (arXiv:2506.09170) and real data (arXiv:2408.08949). With the CHIME collaboration, I'm currently working on detecting the 21-cm auto power spectrum, a major step toward CHIME's ultimate science goal of constraining the dark energy equation of state using neutral hydrogen. 

Radio experiments are detecting mysterious bright transient events called fast radio busts (FRBs). The dispersion of their radio signal is a direct measurement of electrons along the line of sight. Extremely challenging to observe with conventional approaches, these electrons in the intergalactic medium account for most of the baryons in the universe. Their distribution is highly sensitive to galaxy feedback, a poorly understood process in galaxy evolution and cosmic structure formation. Along with my undergraduate mentee and graduate student colleague, I have developed simulations to cross-correlate FRB dispersion with galaxies using IllustrisTNG  (arXiv:2506.03258), offering insights on how systematic errors of radio experiments affect the detection of cosmic baryons. Using the second CHIME/FRB catalog, I have made the first significant detection of large-scale cosmic baryon distributions by cross-correlating FRB dispersion with galaxies in Fourier space, finding evidence for strong galaxy feedback that drives baryons out of galactic halos (arXiv:2506.08932).



My past work includes helioseismology with Dr. Edward Rhodes and pulsar timing array with Dr. Stephen Taylor and Dr. Michele Vallisneri (see arXiv:1904.05355).

I'm a member of the Canadian Hydrogen Intensity Mapping Experiment (CHIME).
