"TIPPERS: A Test Bed to Explore IoT Privacy in Bren Hall"
Nalini Venkatasubramanian, Professor, Dept. of Computer Science, UC Irvine
The Internet of Things (IoT) will enable a vast amount of unprecedented services but will also engender considerable privacy risks. We present TIPPERS, a large collaborative project that explores the extent to which privacy can be preserved in the development of an IoT environment in an office building. Various technical and user-oriented privacy technologies will be tested in two IoT environments: (a) a commercial building management system with flexible interfaces that support mechanisms to retrofit privacy technologies, and (b) an experimental research system designed ground up to embody the “privacy by design” principle.

Nalini Venkatasubramanian is a Professor of Computer science at the University of California, Irvine.  She is known for her work in effective management and utilization of resources in the evolving global information infrastructure. Her research interests are Networked and Distributed Systems, Internet technologies and Applications, Ubiquitous Computing and Urban Crisis Responses. Born and raised in Bangalore, she received her Ph.D in Computer science from University of Illinois, Urbana-Champaign in 1998. From 1991 to 1998, she was a member of technical staff and software designer engineer for Hewlett-Packard.  In 1998, she joined the University of California, Irvine as an Assistant Professor of Computer science.

"Studying the Quantified Workplace"
Yiran Wang, Graduate Student, Dept. of Informatics, UC Irvine
Understanding factors associated with the workplace experience are important in order to develop solutions to improve health and mood. However, cognitive, emotional, and behavioral measurements of the workplace experience until recently have been constrained by methodologies which used infrequent measurements or self-reports. The ongoing revolution in the development of sensor technologies is enabling new ways to measure human behavior in situ with precision. In this talk I will present research from three studies which tracked 85 participants in the workplace over multiple days. We took a multi-faceted view of the workplace experience with a mixed-methods approach using sensors, bio-sensors, EMA, Sensecams, actigraphs, and repeated surveys. We collected data on computer activity, affect, stress, focus, sleep, physical activity, productivity, and other factors. This methodology has enabled us to develop models of workplace mood (explaining 48% of the variance), stress, communication, attention focus, multitasking, and email use. Further, the data enables us to understand other workplace experiences such as temporal patterns of behavior. I will discuss the value and challenges of multi-faceted quantitative measures of workplace behavior as we move towards designing interdisciplinary research to study digital behavior.
Yiran Wang is a Ph.D candidate in the Department of Informatics, Donald Bren School of Information and Computer Sciences, at University of California, Irvine. Her advisor is by Prof. Gloria Mark. Prior to joining in UC Irvine, she earned a B.S. in Computer Science from Peking University (Beijing University), China. She is fascinated by how people use digital technology, how technology advancement contributes to societal changes, and how the design and use of technology affect each other in a cultural and political context. With a human-centered approach, her current work focuses on youth and technology.

"Reflections from a Decade of Expert Witness Engagements: A Software Engineering Perspective"
Richard N. Taylor, ISR Director and Chancellor's Professor Emeritus, Dept. of Informatics, UC Irvine
Work as an expert witness in software engineering has provided some valuable and occasionally surprising perspectives on the actual practice of software engineering. Some of these can help shape research directions; others can help improve the practice. This talk will present some of my lessons as abstracted from a wide variety of cases.
Richard N. Taylor is a Professor Emeritus of Information and Computer Sciences at the University of California at Irvine and a member of the Department of Informatics (of which he was chair from its founding in January of 2003 through June, 2004). He received the Ph.D. degree in Computer Science from the University of Colorado at Boulder in 1980. His research interests are centered on design and software architectures, especially event-based and peer-to-peer systems and the way they scale across organizational boundaries. Professor Taylor is the Director of the Institute for Software Research, which is dedicated to fostering innovative basic and applied research in software and information technologies through partnerships with industry and government. He has served as chairman of ACM's Special Interest Group on Software Engineering, SIGSOFT, chairman of the steering committee for the International Conference on Software Engineering, and was general chair of the 1999 International Joint Conference on Work Activities, Coordination, and Collaboration and the 2004 International Symposium on the Foundations of Software Engineering. He was the General Chair for the 2011 International Conference on Software Engineering, held in Honolulu, Hawaii, May 2011.

Taylor was a 1985 recipient of a Presidential Young Investigator Award and in 1998 was recognized as an ACM Fellow. In 2005 he was awarded the ACM SIGSOFT Distinguished Service Award. In May 2008 he received ICSE's "Most Influential Paper Award", along with co-authors Peyman Oreizy and Nenad Medvidovic, for "Architecture-based runtime software evolution" from ICSE 1998. In May, 2009 he was recognized with the 2009 ACM SIGSOFT Outstanding Research Award. In February 2010 he was designated a University of California, Irvine Chancellor's Professor.
