Hasan Ayaz, PhD, is an Associate Professor at Drexel University, School of Biomedical Engineering, Science and Health Systems, Philadelphia, PA and in the Department of Psychology at the Drexel University College of Arts and Sciences, a core member of the Cognitive Neuroengineering and Quantitative Experimental Research Collaborative and with affiliations at the University of Pennsylvania and the Children’s Hospital of Philadelphia. He received his BSc. in Electrical and Electronics Engineering at Boğaziçi University, Istanbul, Türkiye with high honors and MSc. and PhD degrees from Drexel University where he developed enabling software for functional Near Infrared Spectroscopy based brain monitoring and FDA approved medical devices. His research interests include neuroengineering in human computer interaction and neuroergonomics, as well as clinical and field applications of optical brain imaging.

Dr. Ayaz’s research involves understanding the neural mechanisms related to human perceptual, cognitive, and motor functioning with a focus on real-world contexts, utilizing mobile neuroimaging, and deploying neuroengineering approaches for neuroergonomics applications. His research aims to design, develop, and utilize (i.e. to measure->elucidate->enable) next generation brain imaging for neuroergonomic applications over a broad spectrum including aerospace to healthcare. His research has been funded by federal agencies, corporate partners and foundations, and with 200+ publications in international journals and conferences.

Dr. Ayaz serves on the editorial board of multiple international journals (PLOS One, Frontiers in Human Neuroscience, Applied Sciences, and Computational Intelligence and Neuroscience). He is also a frequent reviewer on 50+ other journals. He served as the co-chair of the inaugural and second International Neuroergonomics Conferences, as well as chair/co-chair/keynote speaker for various other conferences and symposiums.
