Research Interests:
Multimodal Interfaces
I am interested in how multiple input modalities can be combined to create innovative and useful applications. My current research focuses on the creation of a speech and gesture-based data entry interface for use by people with disabilities or for people using mobile devices. Other multimodal applications I would like to explore include:
  • Computer assisted learning interfaces (for teaching subjects such as science and language).
  • Information-aware interfaces to assist users with special needs.
  • Interfaces for searching difficult domains (such as all the pages indexed by Google).

    		•
    Parallel Computing
    I have worked on a number of topics in parallel computing:
  • Enabling novices to perform computationally intensive simulations by utilizing parallel computing resources.
  • Approximation algorithms for scheduling tasks in parallel.
  • Applying parallel computing to genetic algorithms.
    • My home page at the Inference Group - University of Cambridge
