Associate Professor, Department of Radiological Sciences

Biography

I am currently working at the Veterans Affairs Greater Los Angeles Healthcare System with both operational and research responsibilities. My research concentrates on structuring textual and image data for improved efficiency of data annotation, information extraction, and summarization. We utilize data mining algorithms (naive Bayes, logistic regression, Bayesian networks, support vector machines, and decision trees) to classify clinical text as well as documents to improve quality control and efficiency within radiology. We have also developed JAVA based Structured Reporting modules utilizing the DICOM standard so to interact with commercial PACS systems. In addition to my research, I have consulted and developed software for Imaging Informatics companies.
