Here is Yongkun Zhang (张永坤), a Ph.D. in Astrophysics from the National Astronomical Observatories, Chinese Academy of Sciences (NAOC).

My research primarily focuses on fast radio bursts, radio signal processing, and the application of machine learning in astronomy. I have also explored various other fields, including using turbulence analysis techniques to study the large-scale structure of the Milky Way from a dynamical perspective with star clusters. I am particularly interested in developing innovative methods to solve complex problems and continuously learning new technologies and tools, some projects can be found in Section Outreach and Other Experience. For more information, please visit Research page and .

As a Chinese astronomer specializing in Radio Astronomy, my interests span transient phenomena, radio astronomy, machine learning, signal processing, and star formation. I possess strong skills in Python, TensorFlow, PyTorch, and web scraping. I am fluent in English and Chinese (native) and proficient in Japanese (N2).

Outside of my professional work, I enjoy engaging in photography, which you can find in my Gallery. Additionally, welcome comments at the bottom of the page.
