Research Interests
Optoelectronics and Biomedical Imaging
My current research is to develop molecular imaging techniques
based on optical methods for study of biological systems. I am also interested
in development of new materials and devices for terahertz generation and
detection, and application to imaging biological systems.
One of my recent projects is optical coherence imaging (OCI) on tumor tissue. OCI provides direct images without computed reconstructions, and is depth-gated, making it possible to fly through scattering tissue as a succession of optical sections. The work was reported in Physics Today (Physics Today, vol. 56, p.9, September 2003) and Science (Science, vol. 301, p.568, 1 August 2003).
