  We briefly review the scientific contributions of the late Prof. Ru-Keng Su
in his academic life. In the area of intermediate and high-energy nuclear
physics, Su explored various topics in high-energy nuclear physics and particle
physics, inclusively about the finite temperature field theory, effective
models for nuclear and quark matter, soliton, and quasiparticle models, among
others. In gravity and cosmology, Su's research primarily embraces black hole
thermodynamics, quasinormal modes, cosmological microwave background radiation,
modified theories of gravity, and AdS/CFT correspondence and its applications.
Besides, many aspects of Su's distinguished impact on the Chinese academic
physics community are discussed. We also summarize the biographical and
academic career of Su. This article is an elaborated version of the memorial
article that will be published in
