Prof. Raghu Ramakrishnan

Raghu Ramakrishnan is a Professor of Computer Sciences and Vilas Associate at the University of Wisconsin-Madison. From 1999 to 2002, he served as Chairman and CTO of QUIQ, a company that developed a novel approach to customer support by facilitating collaboration among customers and capturing that interaction in a reusable knowledge base. His research is in the area of database systems and data mining. He is a Fellow of the Association for Computing Machinery (ACM), and has received a Packard Foundation Fellowship, a Presidential Young Investigator award, and an ACM SIGMOD Contributions Award. He has written the widely-used text "Database Management Systems" (with J. Gehrke).

Prof. Gerhard Weikum

Gerhard Weikum is a Full Professor in the Department of Computer Science of the University of the Saarland at Saarbruecken, Germany. Gerhard is co-author of more than 100 refereed publications, and he has recently written a textbook on Transactional Information Systems, published by Morgan Kaufmann. He received the 2002 VLDB ten-year award for his work on automatic tuning. Gerhard serves on the editorial boards of ACM TODS and IEEE CS TKDE, and he will be program committee chair for the 2004 SIGMOD conference in Paris.


Eugene Agichtein

I am a PhD student at Columbia University. I am working on information extraction from unstructured text. Specifically, I like applying machine learning techniques to improve the quality and scalability of information extraction while requiring little or no manual input.


Brian Babcock

Im a third-year PhD student at Stanford, where my advisor is Rajeev Motwani. My research is mostly in the area of algorithms for processing streaming data, and Ive also done some work on approximate query processing. This is my second summer as an intern in the DMX group. My non-academic interests include soccer, backpacking, and rock climbing.

Ashish Gupta

I am a third year graduate student from University of Washington. Back at UW, I work with Prof. Dan Suciu on processing of streaming XML. Over the summer, I will be working with Vivek, Nico and Sanjay on the View Merging problem, a part of the Autoadmin project. In my free time, I like to watch movies, go trekking and try my hand at virtually any outdoor sport what so ever.

Vagelis Hristidis

My name is Vagelis Hristidis and I just finished my 4th year of the PhD program at UC San Diego. My advisor there is Yannis Papakonstantinou. My thesis (which will be completed within the next year) topic is Keyword Search in Databases. For more information on my research visit my web page at

In my free time I plan to visit the main sights of the city and explore the Pro Club, for which I heard good things. The weather may not be as good as in San Diego, but a change is always interesting J.

By the way, I come from Greece.

Zheng Huang

My name is Zheng Huang. I finished my B.E. in Zhejiang University (P.R.China) in 2002, after which I came to University of Wisconsin-Madison working with Prof. Raghu Ramakrishnan on data mining and databases. Before I came to UW-Madison, I did some work of image/video processing and content-based image retrieval. I once worked as a visiting student at Microsoft Research Asia with Dr. Hongjiang Zhang, Dr. Mingjing Li and Dr. Lei Zhang.

BTW, as many guys from China, I like playing ping-pong. I played tennis and badminton a lot too.

Seung-won Hwang

Hi, I am Seung-won Hwang, a third year Ph.D student from University of Illinois at Urbana-Champaign. I received my MS and BS from University of Illinois and KAIST (Korea Advanced Institute of Science and Technology) respectively. My primary research interest is ranked query processing. Besides computer science, I love playing the violin and backpacking. Im looking forward to visiting national parks in the northwest.

Daniel Kifer

I am a 3rd year PhD student in Computer Science at Cornell. My advisor is Johannes Gehrke, and my research interests are in data mining, specifically, interesting problems in data mining. I am also interested in ping pong, backgammon, ping pong,and, of course, making the occasional bad joke.

Ravi Ramamurthy

I am a graduate student from UW-Madison and I am hoping to finish my PhD sometime next year. I am generally interested in adaptive query processing and this summer I will be working with Vivek and Surajit on the AutoAdmin project. My other interests include playing badminton and playing the violin.

Utkarsh Srivastava

I am a first year PhD student at Stanford University working with Jennifer Widom. I am primarily interested in approximation techniques for stream processing and the design of an adaptive query processing architecture for the same. In my free time I pursue music and a game of pool never hurts!

Qi Su

Im a first year PhD student at Stanford working with Professor Jennifer Widom. I did my undergrad at University of Wisconsin-Madison. I enjoy tennis, golf, volleyball and Muay Thai kickboxing.
