Heyang Long

I am a Presidential Fellow and fifth-year graduate student at The Ohio State University, Center for Cosmology and AstroParticle Physics (CCAPP). I work with Prof. Christopher Hirata on a variety of topics in cosmology and astrophysics to study the structure, composition and evolution of the Universe and help the precision measurements of it. I received my B.S. at Physics in Nanjing University. In leisure time, I am enthusiastic about photography, stargazing, cooking spicy food and petting my sweet little cat Batian (霸天).
