C. Academic Profile

1. RESEARCH STATEMENTS

Nov 2018 – present              Standardized methods in rehabilitation in cochlear implant users is currently lacking. I have initiated two streams of research that aim to improve rehabilation outcomes in patients with cochlear implants: a brain computer interface and high-density transcranial direct current stimulation.

Sep 2016 – present              We aim to understand the basic neuroscience mechanisms underlying listening ability in cochlear implant users. The knowledge gained from this research will guide directions for rehabilitation programs (see above).

2. TEACHING PHILOSOPHY

My teaching is primarily based on training of HQP (Highly Qualified Personnel) with occasional classroom teaching of undergraduate and graduate students. All HQP coming from my lab will have the ability to think critically and problem solve. These are necessary skills for every researcher and I feel that these skills are honed when making mistakes and learning from those mistakes. In my lab, I will typically give trainees the tools to solve problems and try not to “hold their hand” too much. Although it is always a fine line determining the independence level needed to let trainees “figure it out”.  My lab is also dynamic one with personnel at a variety of career stages (undergraduate to postdoctoral fellows to clinical fellows). I encourage active supervision from more senior lab members to aid with earlier stage students.

Impact Factor 4.5 Role: Senior Responsible Author. (Trainee publication: Smith ML)

Details: This study showed for the first time that neural correlates of listening effort in cochlear implant users can be recorded. Frontal alpha oscillations and phase locking at the level auditory cortex showed significant correlations with listening effort.

Impact Factor 3.9 Role: Senior Responsible Author. (Trainee publication: Smith ML)

Details: This study showed that brain alpha oscillations from different neural generators have different effects on speech in noise perception.

Impact Factor 3.9 Role: Senior Responsible Author. (Trainee publication: Han, JH)

Details: This study showed that speech perception performance in cochlear implant users can be quantified by cortical changes as a function of auditory temporal sensitivity.

Impact Factor 3.9 Role: Senior Responsible Author. (Trainee publication: Han, JH)

Details: This study introduces a novel method of quantifying auditory temporal processing in the brain. We showed that we can generate neural temporal modulation transfer functions and confirmed previous hypotheses that the brain has a hemispheric dominance that operates at different time scales.

Impact Factor 3.1 Role: Senior Responsible Author. (Trainee publication: Alsamri J)

Details: This paper showed that auditory temporal processing in healthy aging can be quantified using the envelope following response to continuously changing modulation depth. With age, the neural modulation dynamic range decreases.

Impact Factor 10.3 Role: Coauthor. (Trainee publication: Wynne DP and Bhatt S)

Details: This paper came about when I noticed that auditory neuropathy patients appeared to adapt to continuous tonal stimuli (see Dimitrijevic et al., 2011, Clin. Neuro., ref 12 below). We formally tested the behavioural adaption and quantified adaptation at the level brainstem. Indeed, depending on the genetic subtype of auditory neuropathy, behavioural and brainstem adaption varied.
