报告题目：Dynamic Group Monitoring in Proximity-based Mobile Social Networks
Various forms of groups exist in social interactions. In recent years, due to the increasing popularity of mobile devices such as smartphones, these dynamic groups can be monitored by exploiting the collaborative capabilities of these mobile devices. In this talk, I will first describe QueueSense, our first-of-a-kind work in collaborative recognition of queuing behavior using mobile phones. I will present a few technical details on what queuing features are extracted and how different queuing lines are partitioned. I will then describe a few highlights of our research efforts on monitoring other types of groups in mobile social networks. I will conclude with a brief discussion of our ongoing research projects in the areas of mobile wireless sensor networks, smartphone sensing, and robotic sensing.
Qi Han is an Associate Professor of computer science in the Department of Electrical Engineering and Computer Science at the Colorado School of Mines. She directs the Pervasive Computing Systems (PeCS) research group. Her research interests include mobile sensing systems and applications, wireless and sensor networking, cyber-physical systems, and robotic sensor networks. She has also been active in interdisciplinary research where she has used wireless sensor networks for different applications such as monitoring of subsurface contaminant and development of energy efficient buildings. Her research has been funded by the National Science Foundation, Department of Energy through collaboration with the National Renewable Energy Laboratories (NREL), and the Petroleum Institute at Abu Dhabi, UAE. Dr. Han received the Ph.D. degree from the Donald Bren School of Information and Computer Sciences at the University of California, Irvine in 2005 and Master's degree in computer science from Huazhong University of Science and Technology in Wuhan. She has served on a number of technical program committees for international conferences and held several workshop or conference program chair positions.
