Field of Study

Professor Yang's research area is biophotonics—the imaging and extraction of information from biological targets through the use of light. His research efforts can be categorized into two major groups – Chip-scale microscopy imaging and Time-reversal based optical imaging.

Chip-scale microscopy - Prof. Yang's group is developing a number of technologies aimed at transforming the conventional microscope into chip-scale, automated and cost-effective formats. His group is the pioneer of the first chip-scale microscope system - the optofluidic microscope. The self-imaging petri dish, ePetri, is the group's most recent major innovation in this research area.

Time-reversal based optical imaging - Prof. Yang's group is working on the use of 'time-reversal' techniques to undo the effect of tissue light scattering. This work has the potential to enable greatly improved depth-penetration and resolution improvement for deep tissue optical imaging. It also opens up the possibility for performing incision-less laser surgery and precision cancer therapy.

Prof. Yang joined Caltech in 2003. He is an Electrical Engineering and Bioengineering professor. He has received the NSF Career Award, the Coulter Foundation Early Career Phase I and II Awards, and the NIH Director's New Innovator Award. Discover Magazine included Prof. Yang as one of the top 20 scientists under 40 in their list of Best Brains in Science 2008.
