Sixu Li, Ph.D. Student at Gatech
I am Sixu Li ("Sixu" is pronounced as "si-hsu" or "sue-hsu"), currently a Ph.D. student at the Georgia Institute of Technology. I received the B.Eng. degree at the University of Electronic Science and Technology of China in 2021.
I have published several papers in peer-reviewed journals & conferences, including TCAS-I/II, TBioCAS, ICCAD, ISCA, MICRO, etc. I have led & participated in several tape-outs in 28nm, 40nm, 55nm, and 65nm.
My research interests are
