Research Projects

This research addresses challenges in understanding and developing lightweight, Web-based informal music education environments that bring the complexity and joy of orchestral music to diverse audiences. The challenges span from providing awareness and appreciation of different classical music genres through creation of multi-instrument musical compositions, in ways that are fun and interactive.

Given the availability of large-scale source-code repositories, there have been a large number of applications for clone detection. Unfortunately, despite a decade of active research, there is a marked lack in clone detectors that scale to large software repositories. In particular for detecting near-miss clones where significant editing activities may take place in the cloned code.

ArchStudio is an open-source software and systems architecture development environment developed by the Institute for Software Research at the University of California, Irvine. It is an environment of integrated tools for modeling, visualizing, analyzing and implementing software and systems architectures. It is based on the Eclipse open development platform.

Bitcoin is a digital currency and payment platform that has been the source of much media attention. The currency is not backed by a government like most conventional currencies but is part of a democratic and dencentralized movement. Bitcoin transactions are pseudo-anonymous in a similar way to cash money. Why do people use this currency? How do their political values align with their usage of bitcoin? Furthermore, how does the community regulate itself in the absence of a formal hierarchical structure? Lastly, how do anonymous users form communities?

We developed techniques for clustering of failures. Failure-clustering techniques attempt to categorize failing test cases according to the bugs that caused them. Test cases are clustered by utilizing their execution profiles (gathered from instrumented versions of the code) as a means to encode the behavior of those executions. Such techniques can offer suggestions for duplicate submissions of bug reports.

To enable much of our research to enable program understanding, software quality, and maintenance, we utilize and develop analyses of program code. These analyses model the flows of information through the logic of programs and systems. With these analysis models enable automated techniques to assist development and maintenance tasks.

Literature about design suggests that a variety of alternatives leads to a higher quality final design. When software designers, either individually or together, are designing in front of the whiteboard, they rarely explore different solution alternatives. How can we help designers to explore more design alternatives for software problems? To achieve this, we are working on a process to facilitate designers to collaborate and produce high quality software designs while considering more solution alternatives.

In the era of big data and personalization, websites and (mobile) applications collect an increasingly large amount of personal information about their users. The large majority of users decide to disclose some but not all information that is requested from them. They trade off the anticipated benefits with the privacy risks of disclosure, a decision process that has been dubbed privacy calculus. Such decisions are inherently difficult though, because they may have uncertain repercussions later on that are difficult to weigh against the (possibly immediate) gratification of disclosure. How can we help users to balance the benefits and risks of information disclosure in a user-friendly manner, so that they can make good privacy decisions?
