I am an astronomer studying the nuclei of active galaxies, using multiwavelength observations across radio, optical, and X-ray regimes.

I am currently an Associate Professor at the Guangdong Technion – Israel Institute of Technology (GTIIT). I was a Lady Davis Postdoctoral Fellow at the Technion – Israel Institute of Technology from 2021 to 2026. I completed my Ph.D. in Astronomy at the University of Padova in Italy from 2016 to 2019. Beyond academia, I enjoy hiking, swimming, skating, and painting.

I have published 43 papers, of which 11 as the first author, in the high-impact astronomy and astrophysics journals, including ApJ, A&A, and MNRAS. The total citation is about 6000 and the h-index is 21 in Google Scholar.

I have been approved 15 observational programs as a Principal Investigator (PI) using international facilities, including VLBA and VLA in the US, EVN in Europe, e-MERLIN in the UK, ATCA in Australia, uGMRT in India, and Gemini in both the US and Chile, with a total time of about 480 hours.
