Jeeseong C. Hwang (Fed)

Jeeseong Hwang is a research physicist in the Applied Physics Division of the Physical Measurement Laboratory at the National Institute of Standards and Technology (NIST). He joined NIST in 1994 as a National Research Council Postdoctoral Fellow, developing near-field optical scanning probe microscopy methods for nanoscale biomimetic materials and structures. Prior to NIST, he was a research scientist at Johns Hopkins University, where he performed super-resolution near-field scanning optical microscopy and other laser-based optical imaging studies in collaboration with AT&T Bell Laboratories. He earned his Ph.D. in physics from Michigan State University, where his thesis research focused on scanning probe microscopy of nanoscale quantum structures and metal surfaces.

Dr. Hwang’s research at NIST focuses on optics and photonics for optical imaging and quantitative molecular physics. His work includes the development and application of multimodal molecular imaging techniques, optical imaging standards and phantoms, and quantitative image analysis software.

Dr. Hwang was named a Fellow of SPIE in 2025. His professional service includes longstanding participation on the program committee for “Quality and Reliability of Biomedical Devices” at the annual SPIE BiOS Conference, where he has served since 2006. He received a NIST/Department of Commerce Silver Medal in 2008 for the development of an innovative nanotechnology tool for highly sensitive and selective optical detection of bacterial pathogens, and he received the Washington Academy of Sciences Award in Biological Sciences in 2012. He has authored more than 100 technical papers, delivered 65 invited talks, and holds six U.S. patents.
