Theongoing convergence of evolution of devices (Internet of Things), deployment oflarge shared infrastructures (computing clouds), and accumulation of Big Data(sensors and social media) has created exciting new research challenges inquality of service (e.g., real-time response time, high availability androbustness despite widespread failures), and quality of information (e.g.,security, privacy, and robustness despite misinformation). These researchchallenges require integration and synthesis of results from several relatedareas, e.g., sensor networks and social networks as Big Data producers,sophisticated machine learning models running on clouds as Big Data consumers,and system support at various levels to provide timely response. We have built LITMUS,a landslide detection system, to illustrate the research challenges ofintegrating physical sensors (earthquakes and rainfall) and social sensors(Twitter, Instagram, and YouTube).


CaltonPu received his PhD from University of Washington and servedon the faculty of Columbia University and Oregon Graduate Institute.  Currently, he is holding the position ofProfessor and John P. Imlay, Jr. Chair in Software in the College of Computing,Georgia Institute of Technology.  He hasworked on several projects in systems and database research.  His contributions to systems research includeprogram specialization and software feedback. His contributions to database research include extended transactionmodels and their implementation.  Hisrecent research has focused on automated system management in clouds (Elbaproject), information quality (e.g., spam processing), and big data in Internetof Things (GRAIT-DM project).  He hascollaborated extensively with scientists and industry researchers.  He has published more than 70 journal papersand book chapters, 280 conference and refereed workshop papers. He served onmore than 120 program committees.
