About

Nikolas Williams has made a significant impact at the intersection of brain-computer interfaces (BCIs) and accessible neurotechnology. His key research areas include portable EEG systems, cognitive neuroscience, and the democratization of neural sensing tools. Williams is best known for his landmark scoping review, “10 years of EPOC: A scoping review of Emotiv’s portable EEG device” (2020, 41 citations), which systematically mapped a decade of research using the Emotiv EPOC—a low-cost, consumer-grade EEG headset. This work critically assessed the device’s validity, reliability, and applications across BCI, cognitive neuroscience, and human-computer interaction, providing an essential resource for researchers navigating the trade-offs between affordability and data quality. By synthesizing findings from dozens of studies, Williams highlighted both the promise and limitations of portable EEG, guiding future work in real-world neural monitoring. His contributions have helped lower barriers to entry in neurotechnology, enabling broader participation in EEG research. With growing citation impact, Williams continues to shape conversations around accessible, ethical, and reproducible neural sensing, making him a key voice for students and researchers exploring low-cost BCIs.
