Kara Brodie

Kara Brodie, MD

At the Children's Communication Center, Kara focuses on evaluating community-based programs for early detection of pediatric hearing loss, and analyzing the impact of genetic testing on evaluation and management of pediatric hearing loss as well as differences in resource utilization for children with unilateral hearing loss or single-sided deafness.

Yasmin Eltawil

Yasmin Eltawil, BS

At the Children's Communication Center, Yasmin works on research that connects educational access and hearing. Her research specifically looks at analyzing Individualized Family Service Plans (IFSPs) and Individualized Education Plans (IEPs) to look for disparities academic access in individuals with hearing loss.

Katie Gutierrez

Katie Gutierrez

Katie's research with the Children's Communication Center investigated disparities in completion of newborn hearing screening and intervention in the US. She utilized a decade of CDC data to identify disparities across maternal age, education, and race/ethnicity, as well as state factors such as program funding and mandates. The goal of the research project was to identify areas for improvement as a medical team works towards timely identification and support for all children with hearing differences.

Michael Lindeborg

Michael Lindeborg, MD

Michael's research with the Children's Communication Center is focused on risk factors for late-identified pediatric hearing loss, ototoxic hearing loss, and healthcare disparities. He is currently working on a project that explores the impact of a patient navigator on delays in hearing intervention for children with newly diagnosed hearing loss, as well as a project that explores unique subpopulations within pediatric patients with late-identified hearing loss.

Wynton Sims

Wynton Sims, MPH

Wynton's work with the Children's Communication Center involves doing a deep dive into the Access Challenge Index in order to further elucidate the specific contributors to access challenges in deaf/hard of hearing children in order to determine which factors are most amenable to intervention. His second project involves performing hearing screening on parents of children with SNHL in order to facilitate access to hearing care for this often underserved population of adults.
