One of Professor Choo's research interests lies in understanding the underlying mechanisms of surface-enhanced Raman scattering (SERS). An unbiased, accurate understanding of the SERS mechanisms will lead to the design and fabrication of nanoscale SERS structures with superior yet uniform Raman enhancement for numerous useful applications. To elucidate the origin of SERS, well-established micro/nanofabrication techniques and creative experimental approaches are combined with numerical simulations and theoretical analysis. The present research effort focuses on assembling an AFM-Raman system that enables the simultaneous observation and correlation of SERS hotspots and the enhancing surface geometry at nanoscale resolution.

Choo received BS and MEng in Electrical and Computer Engineering from Cornell University (1996 and 1998, respectively) and PhD in Electrical Engineering and Computer Sciences from University of California, Berkeley (2007). He has worked at Kionix, Inc. in Ithaca, NY and was a post-doctoral fellow at the Berkeley Sensor & Actuator Center (BSAC) and the Lawrence Berkeley National Laboratory (LBNL), where he worked on micro-/nano-scale optics and surface-enhanced Raman spectroscopy. Choo is a recipient of the Sevin-Rosen Funds Award for Innovation (2007) and the Lim Pre-Doctoral Prize (2003).
