Marlin Johansson

I am a postdoctoral researcher in medicine at the Department of Clinical Science, Intervention and Technology (CLINTEC) in Huddinge, Stockholm, Sweden. My work bridges pediatric medicine and neuroscience, with a focus on otolaryngology and audiology.

In addition to my research, I hold a clinical role as a pediatric audiologist, dividing my time between patient care and scientific exploration. This dual role enables me to apply research insights directly to clinical practice, ensuring the best outcomes for children with hearing impairments.

Through my work, I strive to make a meaningful difference in the lives of children and their families, addressing the challenges of early hearing loss with expertise, curiosity and compassion.

My research focuses on understanding and improving hearing development, diagnostics, and intervention for newborns, infants, and toddlers, with a particular interest in pediatric unilateral hearing loss. My 

Currently, I am leading several prospective longitudinal projects on children with cUSNHL. These studies evaluate hearing, speech, and language development, as well as the benefits of hearing aids, during the first 2.5 years of life, with plans for follow-up assessments at 6–7 years of age. The first two articles from this project, which describe the genetic variants, etiology, and auditory profiles of 20 infants, were published in the Journal of Clinical Medicine (2022, 2023).

In addition, I am working on a project involving young children who are difficult to assess with traditional audiometry, such as those with autism. For this group, we are exploring alternative early diagnostic methods to improve hearing care and intervention outcomes.

To date, I have published five peer-reviewed papers in leading journals, contributing valuable insights into pediatric audiology. My work aims to advance evidence-based approaches to hearing care, improving outcomes for young patients and their families.
