Hi, I am Pei-Chen Peng. I am a postdoctoral scientist at Cedars-Sinai Medical Center, working with Dr. Simon Gayther in the Center for Bioinformatics and Functional Genomics. My research interest lies in computational genomics. I use statistical and machine learning methods, to analyze large-scale omics data. My work focuses specifically on understanding gene regulation in cancer development.

I obtained my Ph.D. in Computer Science from University of Illinois at Urbana-Champaign (UIUC) in 2018, advised by Prof. Saurabh Sinha. I hold a M.S. and a B.S. in Computer Science from National Taiwan University in 2013 and 2011 respectively. I received NIH K99/R00 Pathway to Independence Award and Google Anita Borg Award. I was also recognized as a Rising Star in EECS.

Research Interests

Bioinformatics and Computational Biology. Machine learning and statistical modeling of heterogenous multi-omics data to improve the prevention and treatment of cancer and other diseases.
