Electroencephalogram (EEG) technology, first developed 100 years ago, has become a standard tool in clinical diagnostics and brain research. However, it has historically been a challenge to use on those with afro-textured hair, which has led to the exclusion of a large population in EEG studies. As a postdoctoral fellow, my current work focuses on developing the Sevo electrode adapter, which significantly improves signal quality for people with coarse, curly hair. Our testing shows that Sevo outperforms clinical standards in signal-to-noise ratio while being more comfortable and user-friendly. This innovation not only enhances EEG technology but also brings attention to the broader issue of phenotypic bias in brain sensing devices. In all, my research aims to improve both scientific accuracy and equity in medical care. Read her award-winning essay.
