Principal Investigator

Dr. Hansen He

Senior Scientist, Princess Margaret Cancer Centre, University Health Network
Professor, Department of Medical Biophysics, University of Toronto
Joey and Toby Tanenbaum Brazilian Ball Chair in Prostate Cancer Research, University of Toronto

Dr. He is an experimental and computational biologist at Princess Margaret Cancer Centre. His research program focuses on understanding epigenetic mechanisms underlying cancer development, progression and therapy response, with the aim of identifying epigenetic biomarkers and therapeutic targets to improve treatment outcomes of cancer patients.

Dr. He obtained his PhD in molecular biology and bioinformatics at the Institute of Biophysics, Chinese Academy of Sciences in 2008. He then received postdoctoral training under the joint supervision of computational biologist Dr. Shirley Liu and cancer biologist Dr. Myles Brown at the Dana-Farber Cancer Institute and Harvard University. Dr. He was recruited as a scientist at the Princess Margaret Cancer Centre and assistant professor at the Department of Medical Biophysics, University of Toronto in 2013. He was promoted to senior scientist and associate professor in 2018.

Dr. He is recognized internationally for three discoveries that include pioneering the use of chromatin dynamics to predict transcription factor binding, elucidating the roles of noncoding RNAs in cancer biology and illuminating epigenetic vulnerabilities in cancer cells. Dr. He has authored over 70 publications at high profile journals including Cell (2018, 2019), Nature Genetics (2016, 2020) and Nature Cell Biology (2020). The translational research in Dr. He’s laboratory has resulted in one phase II clinical trial and two patents. Dr. He has received many distinctions and recognitions, including a number of new investigator awards from national funding agencies, as well as being named a rising star in prostate cancer research.

Postdoctoral Fellows


Dr. Yujuan Wang

Postdoctoral Fellow

Yujuan obtained her PhD from Beijing Normal University. She is currently joining the project of prostate cancer m6A profiling to carry out some validation experiments. Next, she is going to carry out a series of CRISPR screens in cancer cell lines, including but not limited to targeting RNA m6A modifications.


Dr. Xin Xu

Postdoctoral Fellow

Xin completed his first postdoc program at the Institute of Microbiology, Chinese Academy of Sciences. After that, he joined He lab in October 2016. Currently, he is working on identifying functional circRNA in prostate cancer, and aim to provide new improved biomarkers and therapy targets that will lead to better diagnosis and treatment of prostate cancer.


Dr. Xinpei Ci

Postdoctoral Fellow

Xinpei obtained her PhD degree in Genetics at Nankai University, China, and received a two-year joint training at Emory University, USA. Her PhD work studied the role of a prostate cancer suppressor gene by using genetically engineered mouse models. She completed her first postdoc training under the supervision of Dr.Yuzhuo Wang at the Vancouver Prostate Centre, UBC, where she utilized patient-derived xenograft models to identify and study driver genes in prostate cancer hormonal therapy resistance. Xinpei joined Dr. Hansen He’s lab in December 2020 and is currently working on epigenetic mechanisms involved in neuroendocrine prostate cancer.


Dr. Tianyi Chen

Postdoctoral Fellow

Tianyi attended Purdue University for college where she majored in Math and Biology. After graduation, she worked as a Research Associate at Indiana University Bloomington for about two years before attending graduate school at Duke University in 2016. For her PhD, she worked on liver regeneration project in which she applied single-cell omics analysis and molecular genetics to understand how mammalian liver orchestrates its effective tissue recovery in response to acute injury. Tianyi joined He lab in September 2022. Outside of the lab, she enjoys reading, hiking, running, and playing with her cat.


Dr. Chengpeng Gui

Postdoctoral Fellow

Chengpeng acquired his MD degree in major of Urological Surgery at Sun Yat-sen University, China. His MD work studied the role of circCHST15 in renal cell carcinoma progression using in vitro & in vivo experiments and mining a genetic predictive model through multi-omics bioinformatics analyses. He seeks to identify and study circular RNAs in prostate cancer precision therapy. He is currently working on circRNA database building, circulation mechanisms and circRNA interaction with TF involved in neuroendocrine prostate cancer.


Dr. Jiaying Li

Postdoctoral Fellow

Jiaying obtained her MD from Sun Yat-sen University, majoring in Urology Surgery. She is currently joining the project of circular RNA in prostate cancer and is going to carry out series experiments.
