I obtained by PhD in astrophysics in 2011 at Peking University (PKU), where I worked with Prof. Xiaowei Liu on nebular astrophysics. During my PhD, I did quantum-mechanical calculations of atomic data (mainly the effective recombination coefficients) for astronomical spectroscopic observations. This program was carried out in close collaboration with atomic physicist and astronomers from the University College London (UCL). From 2011 to 2013, I was a postdoc researcher at the Department of Astronomy at PKU, also at Kavli Institute for Astronomy and Astrophysics (KIAA-PKU). From 2013 to early 2016, I was a postdoc at Instituto de Astrofísica de Andalucía (IAA-CSIC) in Granada, Spain, where I worked with Dr. Martín A. Guerrero on the UV and optical observations of planetary nebulae using the Hubble Space Telescope and the ground-based telescopes, including the 10.4 m Gran Telescopio Canarias (GTC), the flag-ship facility at Observatorio del Roque de los Muchachos (ORM, La Palma) of Spain. Currently, I am a postdoctoral fellow of University of Hong Kong (HKU), working with Prof. Sun Kwok at the Department of Earth Sciences. I am also affiliated with the Laboratory for Space Research (LSR) of HKU directed by Prof. Sun Kwok. My research is multi-wavelength studies of planetary nebulae, and currently mainly focuses on 1) morphological studies of Galactic planetary nebulae, and 2) galaxy evolution using PNe as tracers of chemistry and kinematics.
