My advisor is Prof. Ben Shneiderman, and I am a member of HCIL. My research is in the Information Visualization area of the Human-Computer Interaction field. My current research involves Network Visualization. I developed a tool called NVSS (see NVSS project page) to visualize netwoks (citation networks, food webs, social networks, etc.) using semantic substrates.
Graph mining refers to extracting knowledge from massive graphs. The data sets of telephone calls we see at AT&T can be viewed as a single graph, with several hundred million phone numbers as nodes, and calls between phone numbers as edges. It is a giant social network, like an internet connections graph or a rich citation network.
The Datagram Congestion Control Protocol (DCCP) is a transport protocol that provides bidirectional unicast connections of congestion-controlled unreliable datagrams. DCCP is suitable for applications that transfer fairly large amounts of data and that can benefit from control over the tradeoff between timeliness and reliability.
