I am an Associate Researcher at the Institute of High-Energy Physics (IHEP), Chinese Academy of Sciences, and the TIANFU Cosmic Ray Research Center. Previously, I was a Research Assistant Professor at the Yukawa Institute for Theoretical Physics (YITP), Kyoto University, and a Postdoctoral Scholar at Penn State University. My research focuses on multimessenger and high-energy astrophysics, particularly the origin, acceleration, and propagation of the highest-energy particles in the Universe. I am also a core developer of the Astrophysical Multimessenger Emission Simulator (AMES). My homepage is https://btheodorezhang.github.io/
