Welcome! I'm Ruancun Li
Postdoctoral Fellow at Max Planck Institute for Extraterrestrial Physics
Postdoctoral Fellow at the Max Planck Institute for Extraterrestrial Physics (MPE). My research focuses on high-energy astrophysics, supermassive black holes, accretion disks, changing-look active galactic nuclei (AGNs), and galaxy evolution.
Research Areas
High-Energy Astrophysics
Supermassive black holes, accretion disk physics, and tidal disruption events (TDEs).
Galaxy Evolution and Structures
Active Galactic Nuclei (AGN), feedback mechanisms, and galactic dynamics.
Data Analysis & Machine Learning
Line decomposition, Gaussian process time series analysis, and image structure decomposition.
