I am fascinated with a wide range of aspects relating to sound perception. In particular, I am chiefly interested in the processes of neural oscillations and their relation to speech and auditory processing. This interest manifests itself in two facets

  1. The parsing of speech along multiple temporal scales. This multi-time resolution model is believed to allow for simultaneous processing along the syllabic level (150-300 ms) and the phonemic level (20-50 ms) (Luo & Poeppel, 2007)
  2. The integration of multi-sensory input (e.g. audiovisual) to create a single cohesive percept. The periodic nature of neural oscillations allows for synchronization of two input modes allowing for the two streams of information to merge (Luo et al, 2010).

In both of these aspects of oscillatory activity I hope to further uncover the mechanisms behind these processes and ultimately to link these neural phenomena with the behavioral processes they underlie.
