Feixiong Cheng is a postdoctoral research fellow with a dual appointment at the Center for Cancer Systems Biology, Dana-Farber Cancer Institute at Harvard Medical School, and Center for Complex Networks Research at Northeastern University, Boston, United States. His PhD research focuses on the development of novel computational biology and network pharmacology approaches and tools for systems drug design. From April 2013 to October 2015, he was trained as Postdoctoral Research Fellow at Department of Biomedical Informatics, Vanderbilt University Medical Center in Nashville (USA). His current research interests are focused on development of cutting-edge computational methodologies and infrastructure in the field of network medicine, an emerging interdisciplinary approach that applies systems biology and modern network science methods. The primary goal of his current research is to combine tools from genomics, network science, systems biology, bioinformatics, electronic medical health, and computational biology to address the challenging questions towards understanding of various complex diseases (e.g., cancer, autoimmune diseases, and cardio-oncology), which could have a major impact in identifying novel genomics-driven diagnostic biomarkers and therapeutic targets for precision medicine.
