Virgilio Almeida is a professor of the Computer Science Department at the Federal University of Minas Gerais, Brazil. His research interests include performance modeling and analysis of large scale distributed systems and large social networks. In particular, his current research work is focused on the interaction of social networks and system behavior, including factors such as performance, availability and malicious behavior.
Virgilio is a recipient of a Fulbright Research Scholar Award. He held visiting positions at Boston University, Polytechnic University of Catalunya in Barcelona, Polytechnic University-Brooklyn and held visiting appointments at Xerox PARC and Hewlett-Packard Research Laboratory. Professor Almeida is co-author of 4 books on performance modeling (i.e., "Performance by Design: computer capacity planning by example," "Capacity Planning for Web Services: metrics, models, and methods," ) and is the author of over eighty papers on several topics in computer systems.
Jimi has spent the last 20 years developing and researching cutting-edge information management systems to harness information retrieval, linguistics and machine learning. Prior to being an independent consultant, Jimi was Chief Scientist (and member of executive team) at Turn Inc. where he focused on the development and deployment of an online ad targeting system (CPA/CPC/CPM-based) in a principled and measured way that leveraged advanced statistical and machine learning techniques;These responsibilities included leveraging the entire reservoir of data assets in order to develop methods for identifying key optimizations, deploying relevant analytical tools and improving the user experience. Prior to joining Turn, Jimi was Principal Research Scientist at Clairvoyance Corporation where he led the Knowledge Discovery from Text Group. Before that he was a Research Scientist at Xerox Research Center Europe (XRCE), where, as a member of the Co-ordination Technologies Group, he developed Document Souls, a patented document-centric approach to information access. In the early 90s, he worked on the AI Team within the Mitsubishi Group in Tokyo.
He has published six books and over 50 research publications in the area of machine learning and information processing. Jimi is General Chair for CIKM 2008. Jimi received his Ph.D. in engineering mathematics from the University of Bristol, U. K. and holds a bachelor of science degree in computer science from the University of Limerick, Ireland. He is a Marie Curie fellow and member of IEEE and ACM.
