我的研究聚焦超导探测器及其多通道低噪声读出,面向空间天文观测与精密测量中的微弱信号探测问题。I study superconducting detectors and multiplexed low-noise readout, with a focus on faint-signal detection for space astronomy and precision measurement.

现于清华大学精密仪器系开展研究。博士毕业于荷兰格罗宁根大学,期间在荷兰空间研究所(SRON)从事 TES 阵列频分复用读出研究;随后在清华大学天文系开展科研与博士后工作。研究贯穿超导器件、低温电路、室温电子学、数字反馈与系统验证。I am based in the Department of Precision Instrument at Tsinghua University. I earned my Ph.D. in Astrophysics at the University of Groningen, working on TES-array readout at SRON. I subsequently conducted research and postdoctoral work in Tsinghua's Department of Astronomy. My work spans superconducting devices, cryogenic circuits, room-temperature electronics, digital feedback and system validation.

在既有 TES 阵列与 FDM 读出研究基础上,进一步探索超导量子计算中的复用测控、低温互连与低噪声放大,关注从器件物理到系统扩展的共性问题。Building on TES-array and FDM research, I am exploring multiplexed control and readout, cryogenic interconnects and low-noise amplification for superconducting quantum computing.
