Tianjiao Chu, PhD

Associate Professor Department of Obstetrics, Gynecology & Reproductive Sciences University of Pittsburgh



A major goal of Dr Chu’s research is to develop a sophisticated statistical model for next-generation sequencing and to examine the limitations of this technology, exploring its applications as a diagnostic tool. He also uses informatics tools to analyze mRNA and protein datasets.
