My primary research focus is assisted navigation for the blind and visually impaired. At the USU Computer Science Assistive Technology Laboratory (CSATL), my students and I research and develop assisted navigation solutions that enable individuals with visual impairments to navigate dynamic and complex environments. I am also interested in assisted navigation solutions for people with motor and cognitive disabilities. Click here for more details.
I have a theoretical interest in information retrieval models that combine numerical approaches of classical information retrieval with scaleable knowledge-intensive methods of natural language processing. Click here for more details.
