Welcome to my tiny corner of the web. As you browse my page, I hope the elegant CSS styling and soothing color tones will calm your troubled mind. If you are sitting near an officemate or co-worker, I suggest a series of Platonic hugs, to heighten this feeling. Enjoy!

I am a Ph.D student Ph.D candidate in the Center for Automation Research of the Institute for Advanced Computer Studies in the Computer Science department at the University of Maryland. (*breath*)

My advisor is Prof. Hanan Samet.

My research interests include:

• Geographic Information Extraction
• Spatial Databases
• Parallel and Distributed Computing

I received the Dean's Fellowship Award for 2008-2009.
