category of multimedia content analysis, modeling, and
In particular I'm interested in the applications of multimedia in
The following provides a brief overview of my research. Please see the
publications page for more detail.
joining IBM T.J. Watson research center, I've been working on several
different areas related to multimedia content analysis and indexing.
- Visual event modeling and
recognition in news videos
- Mining multimodal medical
records for decision support
- Concept-based health records
Throughout my doctoral studies I was very
closely involved in one of
the major and multidisciplinary projects in Columbia University. The
project, which was named PERSIVAL, aimed at providing personalized
multimedia summaries of heterogeneous medical data (text of medical
articles, diagnosis reports, patients' history, medical images,
definition of medical terms,...) to users in the health-care. I
was responsible for the image and video part, for which I focused on
content-based analysis, indexing, and summarization of "echocariogram"
I developed innovative methods for modeling the
content of these videos with appropriate spatio-temporal statistical
My research which was funded by DLI-2 program of NSF resulted
in a number of publications both in medical and multimedia related
conferences. I also have 3 patents on the technology that I created
during my research.
Here you can read an interview with me which appeared as the feature
article in the "Health
Imaging & IT" magazine about the future of
the echo videos management.
I strongly believe that information-based medicine and fusion of
heteregeneous medical information for making better decisions in
health-care is going to have a greate impact on the future of medicine.
Because health related information is multi-media in nature, devising
automatic content-based analysis tools to extract knowledge from the
vast amount of medical data is very important in that context.
