Qing Kay Li, M.D., Ph.D., FCAP, Associate Professor
Dr. Li received her M.D. from Tianjin Medical University and her Ph. D. in Cell and Molecular Biology from the Cleveland Clinic Foundation. In addition to providing diagnostic services for surgical pathology and cytopathology, her research is focused on the early detection of lung and prostate cancers, and the separation of aggressive tumors from non-aggressive lung and prostate cancers using state-of-the-art molecular approaches. Recently, we have identified hundreds of proteins and genetic biomarkers in the airway fluid (bronchoalveolar lavage) from lung cancer patients. Our preliminary data shows that these proteins and genetic biomarkers have the potential to improve the accuracy of current lung cancer screening tests and the detection of lung cancers, particularly in patients with small lung nodules. We have also identified several serum protein biomarkers in prostate cancer patients, and these markers have the potential to improve the diagnosis of aggressive prostate cancers.

She established the Mass Spectrometry Core Facility of the Center for Biomarker Discovery and Translation and serves as a Director. Her research focus is on developing high-throughput technologies to characterize dynamic protein expressions/modifications and using these proteomic technologies to understand human diseases. Dr. Zhang participates in several research programs and serves as an investigator in the Early Detection Research Network (EDRN), Clinical Proteomic Tumor Analysis Consortium (CPTAC), NIHBI Proteomics Center, and Programs of Excellence in Glycosciences (PEG).
Zhen Zhang, Ph.D., Associate Professor
My research interests are in the development and application of bioinformatics tools for clinical diagnosis. What used to be considered as a single diagnosis may actually consist of a number of different phenotypes with distinguished disease pathways and varying genomic and proteomics expression patterns. I am interested in deriving new mathematical and computational algorithms to identify such patterns for biomarker discovery and use them to establish predictive models for the diagnosis and management of diseases. Currently, our effort is focused on tumor marker discovery using high throughput proteomics approaches.
