Welcome to my academic website! I am Zhenjie Liu, and I am a 5th year PhD student in the School of Physics and Astronomy at Shanghai Jiao Tong University. My research primarily focuses on using weak gravitational lensing to probe the nature of dark matter halos, explore the properties of galaxy clusters, and constrain cosmological parameters. I am particularly interested in
- Weak gravitational lensing as a probe of cosmology and large-scale structure;
- Dark energy, modified gravity, and other extensions beyond ΛCDM;
- Shear measurement techniques, data processing, and statistical analysis.
You can find a list of my publications below, including recent studies on halo ellipticities, the dependence of halo properties on central galaxy characteristics, and novel methods for cosmology inference from shear-shear correlations. I am always eager to discuss new ideas and collaborations, so please feel free to reach out if you find my research interesting!
