Academic Interests

My areas of interest include listeners’ willingness to listen to speech in background noise and resulting effects on amplification success rates, temporal processing abilities of listeners, and central auditory processing disorders with normal and impaired populations.

Future Goals and Aspirations

Future research goals include exploring factors that contribute to amplification success rates via the acceptable noise level measurement. In addition, I wish to further develop my temporal processing experience into a second line of research. This second line of research includes a short term goal of studying the influence of the gender of the primary talker and the gender of the listener for varying speaking rates. A long term goal for this line includes developing evidence based practices for the improvement of speech understanding in quiet and in noise when applying communication strategies and aural rehabilitation that improve temporal processing. Additionally, I would like to expand this line from cognitively normal individuals to individuals with traumatic brain injury.

Life Outside the University

All of my spare time at the moment is going towards finishing my clinical doctorate in audiology and my Ph.D. from the University of South Alabama.
