BIOMED Seminar

Using Light for Functional Brain Imaging (FBI): Techniques and Applications to Advance Human Health and Performance

Kurtulus Izzetoglu, PhD
Associate Professor
School of Biomedical Engineering, Science and Health Systems
Drexel University

Behavioral measures and subjective metrics have been widely used to assess underlying brain activity changes associated with the performance outcomes. However, recent advances in wearable and portable brain imaging technologies have shown to provide biometrics directly driven from brain processing and neurophysiology, potentially validating subjective measures, and ultimately advancing health and performance assessments. The past two decades have seen the growing importance and implementation of these technologies, particularly the ones relying on optical sensors in providing measures of neurophysiological changes in the field studies, such as for designing effective and efficient human-autonomy teaming, or in clinical settings, such as for assessing cerebrovascular reactivity for traumatic brain injury, monitoring anesthesia care, or assessing and managing hemorrhage.

This seminar will discuss key optical techniques of interest when deploying the methodology as a clinical assessment tool or utilizing it to understand the complex relationships between mental workload, task load, learning and training. Following the discussion on the physical and physiological principles of biomedical optics methodology, its instrumentation techniques to extract relevant biometrics, and their technology evolution, several field and clinical studies will be introduced whereby wearable optical systems, such as functional near infrared spectroscopy (fNIRS) and diffuse correlation spectroscopy (DCS) are employed.

Kurtulus Izzetoglu, PhD, is an associate professor in the School of Biomedical Engineering, Science and Health Systems, and an affiliate faculty member in the School of Education at Drexel University. Dr. Izzetoglu’s research and teaching interests are in biomedical optics, neuroengineering, wearable brain imaging technologies, and biomedical signal processing. He has training in both electrical and biomedical engineering, and experience of developing highly portable optical systems for use in field applications and translational neuroimaging. Over the last decade, he has also focused on the development of performance and training assessment biometrics via wearable biosensors applicable to field settings.

Dr. Izzetoglu's current research projects related to human performance assessment include the integration of biosensors for adaptive and personalized training in safety critical tasks; brain-in-the-loop studies to improve simulation-based training both in clinical (nurse, surgeon training) and in aviation (autonomous systems, manned or unmanned aerial systems); and effects of immersive VR interventions on learning.  His current clinical projects include optical sensor and algorithm development for assessment of hemorrhage and cerebrovascular reactivity in traumatic brain injury, as well as depth of anesthesia monitoring.
