Biography
Dr. Xia Yang received her Ph.D. in Molecular Genetics and Bioinformatics from Georgia State University and had postdoctoral training in Systems Genetics at UCLA. She was Senior Research Scientist at Rosetta Inpharmatics/Merck & Co. and Director of Systems Biology at Sage Bionetworks prior to returning to UCLA as a faculty member.
Research Interests
Our research focuses on developing and applying multitissue multiomics systems biology approaches to dissect the molecular networks underlying diverse complex diseases, ranging from cardiometabolic diseases to neurodegenerative and neurological disorders, and utilize the systems level networks to guide precision medicine. Through integration of genetic, transcriptional, epigenomic, proteomic, gut microbiota, and phenotypic data from human and rodent populations, we investigate how complex interactions between genetic and environmental risk factors perturb tissue- and cell-specific gene networks which in turn induce variations in disease susceptibility. Subsequently, we use the causal molecular networks of diseases as the basis for therapeutic target identification and biomarker discovery.
