Our research at the convergence of biomedical engineering, neuroscience, and human factors focuses on understanding the relationship between non-invasive assessments of neural and physiological activity and the cognitive and physiological state of the person. This research spans basic science (e.g. identification of new imaging biomarkers), technology development (e.g. creation of portable non-invasive technologies), clinical research (e.g. at patient bedside), and real-world demonstrations (e.g. in-aircraft pilot monitoring). Our research combines advanced tools such as functional near infrared spectroscopy (fNIRS), electrocardiography (ECG), electroencephalography (EEG), and transcranial direct current stimulation (TDCS) with engineering techniques (e.g. signal processing, machine learning, etc.) to create novel portable technology-based solutions, with the aim of both advancing our understanding of brain and body function as well as improving patient clinical outcomes and optimizing human performance in high-risk settings such as aviation and space.


Sample previous and on-going projects include the invention of vital signs for the brain, identifying new imaging-based biomarker to detect higher-level cognitive functions, development of novel signal processing techniques for complex environments such as aircrafts, improving the assessment of patients with disorders of consciousness, and developing the first machine learning-based assessment of helicopter pilots’ workloads using physiological data.
