Clinical Molecular Specialist
Dr. Shi joined the GGC Molecular Diagnostic Laboratory as a Clinical Molecular Specialist in 2017. She is mainly responsible for data review of clinical testing and research and genetic variant interpretation. Additional responsibilities include investigating novel testing methodologies and participating in the development of new diagnostic assays and procedures.
Dr. Shi is certified in Molecular Biology (MB) by the American Society of Clinical Pathology. Her clinical research work in the Molecular Diagnostic Lab at the University of Texas M.D. Anderson Cancer Center focused on identifying low prevalence mutations using circulating cell-free DNA for cancer diagnosis. Her postdoctoral research included signaling pathway studies of the central regulation of glucose homeostasis through gut-brain peptide by using knockout and pharmacogenomics mouse models and metabolomics study by using a 3D-cultivated mini-gut model. She has numerous publications in prestigious journals, has been awarded by the American Physiological Society, has one funded grant (2016-2019), and two patents being filed.
