Qiao Li
Overview
I have over 20 years of experience in physiological data analysis, machine learning and advanced signal processing. I worked on developing and evaluating advanced Intensive Care Unit patient monitoring methods and analyzing vital signs waveforms from a complex Intensive Care Unit database, which led to the Martin Black Prize 2008 from the Institute of Physics. The goals of my research are to extract the correct physiological parameters by data fusion, data mining and deep learning and provide the clinicians with interpretations of pathophysiological states, diagnostic hypotheses modeling and decision supporting. I have developed state of the art signal quality indices for bedside monitor data streams, including signal quality indices for the electrocardiogram, arterial blood pressure and photoplethysmogram. Signal quality indices are applying to clinical monitoring as quality control and to data fusion research as important weighting factors.
