I am a fourth year Applied Physics student in Professor Van Duyne’s group. Before coming to Northwestern University, I earned a B.S. in Physics from Nanjing University in China. As an undergraduate, I studied the optical nonlinearities of Au nano-triangles via Z-scan technique using a femtosecond laser. Currently, I am working on single molecule tip enhanced Raman spectroscopy and electrochemistry. In my spare time I enjoy cooking, sailing and badminton.
