Biosketch

My research interests aim to understand the molecular mechanisms governing prostate cancer progression and therapeutic resistance. My background is in prostate cancer biology, ubiquitination, epigenetics and transcriptional gene regulation.The experimental approaches used in my laboratory include molecular cell biology, biochemistry,  transgenic mouse prostate cancer models (PTEN or Hi-Myc), and various genome-wide approaches (e.g. RNA-seq, ChIP-seq, ATAC-seq PRO-seq, Hi-ChIP, et al). We have also established stable collaboration with the experts in prostate cancer pathology or systems biology. Our studies reveal key roles for histone demethylase, ubiquitin ligases and oncogenic transcription factors in prostate cancer progression, and further understanding their mechanisms is critical towards identifying new targets and developing new rationale therapies for the advanced prostate cancer.
