Research interests

My research objective has been to develop algorithms that analyze, process, and extract meaningful information from auditory scenes. Auditory scenes contain valuable information, including speech, source location, music, and emergency alerts such as a passing police car. Humans with normal hearing naturally analyze auditory scenes, but computer systems and humans with hearing impairments struggle to perform this task. My goal as a researcher is to develop algorithms that address this problem in realistic and challenging auditory environments.
