Research Projects

In addition to the dynamic nature of software while executing, this dynamism extends to the evolution of the software's code itself. The software's evolution is often captured in its entirety by revision-control systems (such as CVS, Subversion, and Git). By utilizing this rich artifact, as well as other historical artifacts (e.g., bug-tracking systems and mailing lists), we can offer a number of techniques for recommending future actions to developers.

Collaboration is becoming ubiquitious; at the same time the emergence of new technologies have been changing the landscape of interaction and collaboration. I am interested in the effect that information technologies have on collaboration and the development of new organizational practices such as network-centricity, group-to-group collaboration, nomadic work, and large-scale collaboration. I am also very interested in how Web 2.0 technologies (blogs, wikis, social-networking sites, etc.) are used in collaboration and how they can be integrated into the course of daily work.

Cross-situational personality consistency has been of interest in social psychology since the 1960s. With the advent of the Internet, a new range of “situations” has been presented for investigating human behavior in online environments.

Sustainability has become a pressing concern, especially given the looming effects of climate change. Sustainable development aims to meet current needs while ensuring sustainability of natural systems and the environment so as to not compromise the ability of future generations to meet their own needs. Current software engineering methods, however, do not explicitly support sustainability or sustainable development.

The development of a software system is now ever more frequently a part of a larger development effort, including multiple software systems that co-exist in the same environment: a software ecosystem. Though most studies of the evolution of software have focused on a single software system, there is much that we can learn from the analysis of a set of interrelated systems. Topic modeling techniques show promise for mining the data stored in software repositories to understand the evolution of a system.

This research focuses on techniques for identifying and reducing the costs, streamlining the process, and improving the readiness of future workforce for the acquisition of complex software systems. Emphasis is directed at identifying, tracking, and analyzing software component costs and cost reduction opportunities within acquisition life cycle of open architecture (OA) systems, where such systems combine best-of-breed software components and software products lines (SPLs) that are subject to different intellectual property (IP) license requirements.

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.

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.
