Current projects in my lab

  • Creation, prototyping, and usability testing of an auditory assistive device that amplifies sounds coming from the direction of the user’s eye gaze
  • Development and evaluation of a sound source separation algorithm
  • Using eye gaze as an indicator of auditory spatial attention
  • Adaptive auditory warnings for smart vehicle interfaces
  • Using haptic systems to complement auditory perception
  • Using trans-Cranial Direct Stimulation (tDCS) to enhance auditory perception
  • Development and evaluation of an algorithm to provide approximate solutions to the set cover problem in combinatorics
