Joshua Alexander is Associate Professor in Speech Language and Hearing Sciences at Purdue University. His research focuses on hearing aid technology, speech perception mechanisms, and auditory rehabilitation. Key areas include frequency compression algorithms, music quality enhancement in hearing devices, and neural coding of auditory signals in hearing impairment.

Recent work develops novel diagnostic methods like the PHIG technique for feedback quantification and investigates tonotopic distortions in sensorineural hearing loss. His lab also explores open-source hearing aid platforms and ear monitoring systems using speakers as sensors.
