I am a PhD candidate in Survey Methodology at the University of Michigan. My research focus is mainly concerned with finite population inference for Big Data as large-scale non-probability samples. Currently, I am working as a graduate student research assistant under the supervision of Professor Michael R. Elliott and Dr. Carol A. C. Flannagan at the Survey Research Center, Institute for Social Research. Read more . . .
