Research Projects

I have several research projects that I work on, but the common connection is novel problems, rigorous formulations and practical applications. I typically work with other faculty/researchers to apply my work so if you can see some potential application then please let me email me.

I have several research assistantship slots available for students who are motivated to do research in data mining. My research is a mix of rigorous algorithm design, implementation and application to novel areas of social importance. Please read some of my work and contact me if your genuinely interested. Do NOT send form letters.
