Ph.D. in Bioengineering, University of California-Berkeley and San Francisco, 2006

Research Statement:
We study how electrons, photons and ions commute between solid-state nanoscale electronic/photonic systems and soft-state nanoscale biomolecular systems. The created hybrid nanobionics will be used for the applications of healthcare, renewable energy and environment protection. My current research projects include: 1. designing, modeling and fabrication of nanoscale light harvesting devices to concentrate and enhance electromagnetic field for energy conversion and biomolecular sensing applications; 2. designing and fabrication of nano-bio hybrid molecules by conjugating endogeneous biomolecules with artificial nanophotonic molecules for nucleotide and enzyme imaging and manipulations; 3. Label-free living cell spectroscopic imaging facilitated by micro and nanoscale optoelectronic devices.

Teaching Statement:
I am teaching ECE450, "lines, fields and waves" in spring 2009 semester and this course is about the applications of classic electromagnetic theory in state-of-the-art microwave communications, optoelectronics and photonics. Besides theoretical and applied electromagnetics, I am interested in teaching courses related to micro and nanofabrication, solid-state electronics theory and applications. I am also designing a new graduate course that will help engineering students to study molecular and cell biology using familiar engineering modeling, analysis, and characterization methods.
