Research Field
I am an associate professor at the National Chung Hsing University with a research interest in ‘transient objects, including gamma-ray bursts and fast radio bursts and their host galaxies’. http://www.phys.nthu.edu.tw/~tetsuya/
We are working on extragalactic transients in astronomy, including mysterious fast radio bursts.
I am working on mysterious fast radio bursts to reveal their origins and to address key science in astronomy and astrophysics, including dark energy, dark matter, cosmic reionization, and testing general relativity.
I had 58 publications (11 first-author papers and 47 co-authored papers) in the last five years. Three papers were selected as press releases. Eight papers were featured by a total of more than 50 media.

Job Description
Contributing to the BURSTT project
Fast radio bursts (FRBs) are bright and instant radio pulses with extragalactic origins. FRBs are about 10 orders of magnitude more energetic than well-known pulsar populations, making them one of the most outstanding enigmas in astronomy. Taiwan is building a new radio telescope dedicated to finding FRBs in the local Universe, the Bustling Universe Radio Survey Telescope in Taiwan (BURSTT). The successful candidate will contribute to (i) developing the data analysis pipeline, (ii) constructing the main/outrigger stations, and (iii) participating in scientific discussions with new BURSTT FRB data under the supervision of Dr. Kai-Yang Lin at ASIAA and Tetsuya Hashimoto at NCHU. The student is also highly encouraged to interact with the local students and research scholars.

Job Description
Search for a gravitationally lensed fast radio burst in CHIME catalog 2
Fast radio bursts (FRBs) are coherent radio pulses with extremely high temperatures. The bright signals allow us to detect them at the cosmological distances. During FRBs' travel in the Universe, there is a chance for FRBs to encounter a significant gravitational potential, which might cause the ‘gravitational lens’. Some theoretical studies predict gravitationally lensed FRBs with a probability of ~0.03% for a strong galaxy-galaxy lens, 0.1% for a microlens, and a few % for hypothetical primordial black holes (if exists). However, there is no confirmed case of lensed FRB so far, mainly due to the limited number of FRB detections. If it is found, the scientific impact is extremely high. In 2026, the Canadian Hydrogen Intensity Mapping Experiment (CHIME) changed the situation. They released more than 4000 FRB detections along with their dynamic spectra, which are necessary for the analysis of lens search. Therefore, a few lensed FRB events could be found in the CHIME samples. This project aims to compute cross-correlation between FRBs' dynamic spectra to find a potential candidate for a gravitationally lensed event with CHIME catalog 2.
