Celesta Lim Chang serves as an Assistant Professor in the Department of Physics and Astronomy at Seoul National University since 2023, specializing in condensed matter physics with emphasis on nanoscale phenomena and photonics through advanced electron microscopy techniques.
Her academic background includes:
- Ph.D. in Physics from Cornell University (2020)
- B.S. in Physics from Yonsei University (2014)
Research focuses on utilizing scanning transmission electron microscopy (STEM) for picometer-scale structural and chemical analysis of oxides, alongside pioneering methods to create freestanding membranes that reveal novel behaviors as 3D materials approach 2D states. Key investigations span nanoscale physics, photonics, 2D materials, and oxide semiconductor properties.
Recent publications (2021-2023) demonstrate consistent high-impact contributions across Nature Nanotechnology, Nature, and Science Advances, revealing strong thematic continuity in epitaxial growth mechanisms, 2D material synthesis, and defect engineering in oxide systems with direct relevance to next-generation semiconductor devices.
Key recognition includes:
- NSF Graduate Research Fellowship (2015-2020)
Currently establishing her research program at SNU, she directs laboratory operations in rooms 23-108/109 with active recruitment of graduate students for microscopy-based materials research, supported by institutional startup funding and prior NSF fellowship resources.
Experimental facilities focus on aberration-corrected STEM instrumentation for atomic-scale materials characterization, complemented by specialized sample preparation techniques for freestanding membrane studies as detailed on her research portal https://www.celestachang.com/.
