I am a research staff member at the IBM T.J. Watson Research Center, where I spend most of my time researching, designing, and building software that attempts to be engaging and supports useful discovery and collaboration. As a computer science researcher I have worked in a variety of areas, including cognitive computing, theory and algorithms, computing from the large (parallel) to the small (mobile), graphics, multimedia, compilers, and programming tools and IDEs.
My main current focus is around cognitive computing, where I create and study user interfaces for communicating with smart systems with a goal of augmenting human potential. New emerging capabilities in machine learning and reasoning require rethinking how best to interact with these systems. I have led work around smart rooms with significant audio-visual capabilities and cognitive agents that leverage these capabilities. Additionally, I have been working on tools for supporting management and discovery in mergers and acquisitions (M&A).
I have been active in human-computer interaction, studying how novel visualization techniques can promote discovery and collaboration. In this space I lead the Event Maps project, a collaborative schedule visualization tool that has been used at several events and conferences including CHI 2010, Lotusphere 2011 and CHI 2011. Before that I led the OrgMaps project, for visually navigating large hierarchical organizations. A precursor to this line of research was work on visual mashups in public spaces incorporating mobile and infrastructure devices. I led this research as part of the Celadon project, a joint collaboration with the IBM Ubiquitous Computing Lab in Korea.
At IBM Research I have worked on a wide range of topics, including a parallel processing system for video editing and effects (EFX), an extensibility system for the Visual Age C++ compiler, a Java toolkit for the CrossPad, and several application-developement tools including the Multi Device Authoring Technology and Pegboard.
I received my B.S. in Computer Engineering and M.S. in Electrical Engineering, both from the Technion, Israel Institute of Technology, and my Ph.D. in Computer Science from the University of California, Berkeley.
