Hao Harry Feng, PhD

Assistant Professor
Department of Population and Quantitative Health Sciences
School of Medicine
Population and Cancer Prevention Program
Case Comprehensive Cancer Center

Dr. Hao Feng develops and applies biostatistical and bioinformatics approaches to better understand high-throughput omics data. He utilizes epigenetic data to define biomarkers, predict and classify disease subtypes. His approaches has wide applications in cancers and neurological studies, such as liver cancer, Alzheimer’s Disease (AD) and PTSD. He also has collaborated in researching how Zika virus alters transcriptome, and how environmental radiation exposure induces epigenetic variables that inform lung cancer. 

Working in industry and academic medicine, he has developed Bayesian methods to study tumor growth inhibition and has developed statistical models for the analysis of genetics data, with applications to cancer immunology and trauma research.

Research Interests

My research interests include biostatistics, bioinformatics and computational biology. My main focus is to develop and apply biostatistics and bioinformatics methods to better understand high-throughput omics data, with an emphasis on applications in cancer. I utilize epigenetic data to define biomarkers, classify cancer subtypes and predict disease in cell-free DNA. I developed a number of open-source software tools that are freely available on Bioconductor and R-CRAN, with over 10,000 downloads annually. These tools have been widely used in studies on various cancer types. I collaborate closely with physicians and wet-lab researchers to decipher signals from cancer genomics and epigenomics data.
