I am a first-year PhD student in theoretical physics at Sun Yat-sen University, working under the supervision of Professor Chengcheng Han. My research interests are in cosmology and fundamental physics, with a focus on dark matter, large-scale structure formation, and primordial black holes (PBHs). I have previously worked on topics related to the evolution of large-scale structures and dark matter phenomenology. Recently, I have been exploring PBH formation and their connection to early-universe physics. I am particularly interested in cosmic inflation and primordial perturbations, and how they can provide insights into the origin of structure in the universe.
