Sean Lineaweaver

June 10, 1969 ~ August 31, 2022 (age 53)


Sean Lineaweaver, age 53 of Gig Harbor, died on August 31, 2022 following a long battle with multiple sclerosis. Sean grew up on Greenwood Village, Colorado. He attended the University of Colorado, Boulder, earning a BS in Aerospace Engineering in 1991 and a MS in Electrical Engineering in 1994. He moved to Seattle in 1994 to attend the University of Washington with the intention of earning a PhD in Electrical Engineering. Sean was a rocket scientist who decided to become a brain scientist.

His career was devoted to research and innovation with cochlear implants. He was hired at Cochlear Limited in 2003, where he spent much of his career. He defined himself by his work, particularly with “The GA” (genetic algorithm). He wanted to develop technology that ultimately helped people and provided effective interface for clinicians. As a person who understood issues of access, inclusion, and parity, he wanted people who chose cochlear implants to have optimized experiences. He was passionate about work that improved outcomes for patients and the clinicians who served them. He was a prolific developer of intellectual property for Cochlear, filing forty-two patents for his work with machine learning, artificial intelligence, cochlear implant fitting and training, and cochlear implant optimization. He also has the distinction of being listed as an author of a study presented after his retirement. He accomplished all of this while battling unrelenting symptoms of multiple sclerosis, which included constant fatigue, paralysis, depression, processing challenges, and cortical blindness. He was unrelenting and creative in his work ethic and drive.
