About me

I am a 4th-year Ph.D. student at Rutgers University, working with Prof. Waheed Bajwa. Before coming to Rutgers, I obtained my M.S. degree in Electrical Engineering from Duke University in 2011. My advisors were Prof. Robert Calderbank and Prof. Ingrid Daubechies. I received my B.S. degree in Instrument Science and Engineering from Shanghai Jiao Tong University in 2009. More information about me can be found at my Linkedin page.
