Dr. Charles Choi

Charles received his Ph.D. in Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign in 2011. His thesis research was on the study and development of label-free optical biosensors.

Charles is working in the Biochemical Science Division at NIST as a NRC postdoctoral fellow where he is developing dual-mode sensing capabilities consisting of surface plasmon resonance (SPR) and surface-enhanced Raman scattering (SERS) with nano-structured sensors. This work enables detection of a wide range of analytes (chemicals, proteins, bacteria, etc.) in a single sensing platform.
