Johanna Nagy

Johanna Nagy is the Warren E. Rupp Assistant Professor of Physics at Case Western Reserve University, where she leads the Nagy Lab in the Department of Physics. Her work bridges experimental cosmology and astronomical instrumentation, focusing on precision measurements of the Cosmic Microwave Background (CMB) to unravel cosmic evolution and particle physics.

• Ph.D., Case Western Reserve University (2017)
• B.S., Stanford University (2010)

Her research probes the early universe through CMB radiation, utilizing balloon-borne (SPIDER, Taurus) and ground-based (CMB-S4) experiments. She designs low-temperature detectors, optics, and calibration systems to enhance data accuracy, with applications in studying cosmic inflation, reionization, and fundamental particles.

Recent publications emphasize advancements in CMB instrumentation, optical systematics, cryogenic architectures, and diffraction-limited imaging from stratospheric platforms. Collaborative projects like CMB-S4 and SuperBIT highlight her interdisciplinary approach.

• Warren E. Rupp Assistant Professor of Physics

The Nagy Lab operates in Rockefeller Building 203 (Office) and 16 (Lab), focusing on detector development, calibration, and data analysis for CMB experiments. Her team contributes to global collaborations, including SPIDER, Taurus, and CMB-S4.
