Dr. Liu received her PhD in Bioengineering from the University of Pennsylvania in 2006, where she developed a patented automated technique for optimal boundary detection in medical images. Dr. Liu holds an MS and BS in Electronic Engineering from Beijing Normal University in China. She is currently a Staff Scientist in the Imaging Biomarkers and Computer-Aided Diagnosis (CAD) Laboratory, Radiology and Imaging Sciences, at the National Institutes of Health. Dr. Liu’s research interests include medical image analysis in general with a focus on segmentation, registration and computer-aided detection. She is an associate editor of Medical Physics and reviewer for IEEE TMI, IEEE TBME, Medical Physics, Pattern Recognition Letters, and MICCAI.
