Siqiang Luo (骆思强)

HI! I am Siqiang Luo (骆思强 in Chinese). I am currently a 3rd year Ph.D. student in the database group at University of Hong Kong, co-supervised by Prof. Ben Kao and Prof. Reynold Cheng. Before that, I got my bachelor's and master's degrees from Fudan University (with Prof. Shuigeng Zhou).
