Current Job Title: Assistant Professor, University of South Dakota Speech Language and Hearing Cochlear Implant Clinical Coordinator

Favorite current project: Evaluating the test-retest reliability of portable, retrofittable speaker arrays for clinical settings. In my dissertation, I used the 48-Channel Speaker Array/Sound Field (Booth 1) in the Center for Applied and Translational Sensory Science Lab to help show that a cochlear implant can help partially restore spatial hearing in people with profound hearing loss in one ear and residual hearing in the other ear. Unfortunately, systems like these are not accessible to audiologists due to cost, complexity, etc and current clinic speaker array systems are neither sufficient nor standardized to test spatial hearing. However, they are increasingly important as hearing device candidacy criteria now include rehabilitation for people with spatial hearing deficits. Through an educational partnership with Walter Reed, I’ve been measuring the test-retest reliability of two speaker array systems that could easily fit in clinic spaces and a clinic budget.
If your current job isn’t your first position since leaving the University of Minnesota, where else have you worked? Walter Reed National Military Medical Center as a Research Audiologist. My favorite project there was doing a field study with 1-325 AIR of the 82nd Airborne Corps (shout out A CO!) to evaluate the effectiveness of different types of hearing protection devices in dismounted combat. I spent a month out of the woods at Fort Liberty (day and night) trying to figure out how to objectively measure mission success.
When were you in the APC Lab? June 2013 – April 2020
What position did you have during your time at the APC Lab? PhD student
What was your favorite project/paper from your time in the APC Lab? Testing whether the contraction bias** in pitch perception was more consistent with Bayesian inference or signal detection processes. This project was pivotal for my professional growth and skill development.
**When two pure tones are presented sequentially and roved in frequency from trial to trial, we tend to report that the first tone is closer to the mean of the frequency rove range than the second. In other words, the pitch of the first tone “contracts” toward the mean.
Favorite restaurant to grab a bite to eat in the Twin Cities/campus? Wally’s
Do you have any funny stories about your time in the lab to share? One time, I booked a hotel room at the Marriott on the West Bank for one of my research subjects. He was spending the weekend at UMN with me doing experiments for my dissertation. When the subject checked in, the receptionist said he would be sharing a room with a man named “Andrew Oxenham.” He called me in a panic saying, “I’m sharing a room with someone I don’t know?!” Of course, I talked to the receptionist and cleared it up.
Favorite scientific conference to attend? American Auditory Society. It’s a great blend of basic research and clinical application.
