About me

I am a researcher in the Medical Imaging Informatics Group at UCLA. My work centers on information organization and retrieval in medicine using techniques from machine learning and probabilistic modeling. Other interests include: healthcare economics and policy; informatics for comparative medicine; and the development of web-based medical applications.

Professional Experience

Researcher, Medical Imaging Informatics, David Geffen School of Medicine, UCLA, 2009 - Current
Activities include: radiographic image indexing and retrieval; case-based reasoning/retrieval; web-based medical application development; and teaching.

Intern, IBM Almaden Research Center - San Jose, CA, Summer 2008
Built information (medical literature, clinical trials, etc.) retrieval system driven by a patient's medical record using controlled terminologies (SNOMED CT), NLP (MMTx), and cloud computing technologies (Hadoop, HBase).

Intern, National Library of Medicine - Bethesda, MD, Summer 2006
Performed a two month internship working with research faculty at NLM. Main project involved integrating statistical image segmentation algorithm into plugin for MIPAV.

Dept. of Biostatistics, Washington University in St. Louis, 1/2003 - 7/2003
Worked in the clinical trials core developing web-based tools and documentation protocols using XML technologies for the HALT-PKD and CRISP studies.
