Currently at IBM TJ Watson, I am involved
in a variety of research projects that have come to have an underlying
common theme: the Semantic Web. I've mainly been looking at different
applications of Semantic Web technologies (representation and reasoning)
to improve different system management and operations. The broad areas
My PhD thesis spanned the areas of Pervasive or Ubiquitous Computing, Autonomic Computing, the Semantic Web, Distributed Systems and Middleware. It focused on trying to make large-scale pervasive computing environments easier to program and manage, and smarter in their interaction with humans. Other areas where I did work are context-aware computing, artificial intelligence, security, workflows, human-computer interfaces, social networks and ontologies.
I was a research assistant under Prof Roy Campbell in the Gaia project, which aims to develop a middleware for Active Spaces. Active Spaces are which are physical spaces that have been enriched with devices and services to become interactive, pervasive computing environments. Such environments can be seen as analogous to traditional computing systems; just as a computer is viewed as one object, composed of input/output devices, resources and peripherals, so is an Active Space. However, the heterogeneity, mobility and sheer number of devices makes the system vastly more complex. Applications may have the choice of a number of input devices such as location sensing system, mouse, pen, or finger and output devices, such as an everywhere display, monitor, PDA screen, wall-mounted display, speakers, or phone. I have worked on a variety of pervasive computing issues including modeling, sensing, reasoning about and using context information, ontologies, security issues, location-awareness, mobility, metrics and wearable computing.
