Tiantian Nie

I am a visiting assistant professor in Department of Systems Engineering and Engineering Management at University of North Carolina at Charlotte.

I received my Ph.D. degree in Edward P. Fitts Department of Industrial and Systems Engineering at North Carolina State University in Dec. 2016, under the supervision of Prof. Shu-Cherng Fang. I received my BS degree in Department of Mathematical Sciences at Tsinghua University in Jul. 2012.

My curriculum vitae is here.
