Aifeng (Lucy) Zhang, Ph.D.

Background:

Dr. Aifeng Zhang received her Bachelor degree in Optoeletronics and Master degree in physical electronics from Nanjing Univ. of Sci & Tech., China in 1999 and 2002, respectively; Ph.D. in Image Processing and Image Informatics at the Department of Biomedical Engineering, USC in 2007. She joined the Image Processing & Informatics Laboratory, Department of Radiology as a research assistant. During the past four years she has become a key researcher in the Digital Hand Atlas project. Her PhD dissertation is to augment and extend carpal bone analysis with the existing phalanges analysis to improve accuracy of computerized bone age assessment for children less than 7 years old based on normal digital hand images from four ethnic origins and two genders. Her other research interests include medical image segmentation, feature extraction and fuzzy classification, statistical analysis of medical data, data mining in medical imaging informatics and PACS.
