Three fourth-year graduate students in electrical and computer engineering received the annual Yan Huo *94 Graduate Fellowship, supporting their work in wireless communication devices, quantum technology and photovoltaic materials.
Atsutse Kludze focuses on high-speed and efficient system architectures for future communication and sensing networks, especially within the millimeter wave and sub-terahertz frequency range. His work applies electromagnetic and wireless communication theory to experimental evaluation and prototyping. He is also a Semiconductor Research Corporation Research Scholar, GEM Employee Fellow and recipient of the Department’s 2023 Pramod Subramanyan *17 Early Career Graduate Award. Two of his publications have won best paper awards: at ACM MobiCom 2023 and USENIX NSDI 2023. Prior to joining Princeton, Kludze received his B.S. in electrical and computer engineering from Cornell University. He is advised by Yasaman Ghasempour.
Chengyu Wang studies emergent interaction phenomena in ultra-pure gallium arsenide (GaAs) 2D carrier systems. In particular, he focuses on topological electron liquids called fractional quantum Hall states, which emerge from strong electron-electron interactions. Chengyu has been studying the purest GaAs 2D carrier systems at very high magnetic fields and extremely low temperatures. He has discovered a new class of exotic fractional quantum Hall states which could lead to applications in fault-tolerant topological quantum computing. Chengyu is from Taizhou, China. Before joining Princeton, he earned his bachelor’s degree from Fudan University. He is advised by Mansour Shayegan and works closely with researchers in Loren Pfeiffer's lab.
Zhaojian Xu studies photoelectrochemical degradation of halide perovskite materials and devices. In particular, he works on understanding halide segregation in mixed-halide perovskites under external stress. He intends to use the findings from his work to address the stability issues of perovskite — a leading challenge in advancing solar-energy technology — and accelerate their commercialization. Before joining Princeton, Xu earned his bachelor's degree in physics from Peking University. He is advised by Barry Rand.
