Yang Liu, PhD is an Associate Professor of Medicine and Bioengineering. Dr. Liu integrates multi-disciplinary approaches spanning engineering, optics, physics, chemistry and biology and develops imaging technologies to address important clinical dilemma of how to better predict the individual's cancer progression risk in a large number of at-risk population, and how to improve the diagnostic accuracy of malignancy. Early cancer detection currently relies on screening the entire at-risk population, as with colonoscopy and mammography. Frequent, invasive surveillance of patients at risk for developing cancer carries financial, physical, and emotional burdens because clinicians lack tools to accurately predict which patients will actually progress into malignancy. Current clinical gold standard for diagnosing cancer and predicting cancer progression risk relies on the evaluation of nuclear morphology by a trained pathologist using bright-field microscope, which limits the assessment of nuclear architecture to microscale with very limited performance on a personalized level, especially in patients without the presence of clinically significant lesions such as patients with ulcerative colitis or atypical hyperplasia in breast.

Zongqi Xia, MD, PhD, is an Associate Professor of Neurology.  Currently, he has three ongoing research initiatives. First, we are participating in a multi-centered, prospective cohort study of individuals at risk for MS. Investigating the risk factors of MS and mapping the sequence of events leading to the onset of disease will pave the way to ultimately test primary prevention strategies in high-risk individuals. Second, we are conducting a longitudinal prospective cohort study to investigate the biological and clinical predictors of disease course and treatment response in MS. Gaining insights into the factors that influence the variable patient response to treatment and the diverse trajectories of disease progression in MS will be the key to provide individually tailored therapy. Third, we are developing computational approaches to ascertain treatment response and testing algorithms that predict treatment response using electronic health records data. Tools that leverage real-life clinical data for outcome prediction in chronic neurological disorders have the potential for widespread dissemination at the point of care.
