Ziqiang is a PhD student in Liu Nian's Lab at Tsinghua University. His research focuses on the regulation and function of retrotransposons in the human genome. Ziqiang employs a variety of methodologies, including CRISPR/Cas9 genome-wide screening, next-generation sequencing, biochemistry, molecular biology, human genetics, and bioinformatic analysis. His work aims to elucidate the molecular mechanisms regulating human retrotransposons and to explore their biological and physiological functions, as well as their roles in human development and disease. One of his recent projects investigated the regulatory mechanisms of composite transposons in the human genome, specifically examining their roles in hematopoietic differentiation and hematopoietic aging.
