Principal Investigator

Jeff Ojemann is a neurosurgeon with a practice focusing on the surgical treatment of epilepsy in adults and children. He is Director of Epilepsy Surgery at the Harborview Medical Center and Seattle Children’s Hospital at the University of Washington. He received his MD in 1992 at Washington University in St. Louis, and remained there for residency in neurosurgery (1999) and fellowship in pediatric neurosurgery at St. Louis Children’s Hospital in 2000. He joined the faculty at the University of Washington in 2003 and holds the Richard G. Ellenbogen Chair in Pediatric Neurological Surgery. He has been funded by NIH or NSF continuously since then with present focus on electrical stimulation and current distribution in human and animal models of cortical surface stimulation. He has over 165 peer-reviewed publications, primarily in neuroimaging and human cortical physiology. He is the co-leader of the Cortical co-adaptation with bidirectional brain-computer interface testbed of the Center for Sensorimotor Neural Engineering (a NSF Engineering Research Center).

Principal Investigator

Jeffrey Herron earned his Bachelor’s of Applied Science in Electrical Engineering from the University of British Columbia in 2009. After three years working in the Microsoft Research Hardware Prototyping Lab, he returned to graduate school to pursue a PhD in Electrical Engineering at the University of Washington within the BioRobotics Lab. Following the completion of his PhD thesis in 2016, Jeff moved to Minnesota to work within the Medtronic Restorative Therapies Research and Core Technology team. There he spent three years developing new human-use implantable research tools for improving the treatment of neurological disorders through the application of closed-loop system integration. In 2019, Jeff returned to UW as a research professor in the Department of Neurological Surgery, and rejoined the BRL to continue his research into developing new research tools and systems to explore the applications of bi-directional neural interfaces to enable or improve the treatment of neurological diseases, disorders, and injuries. More at Jeff’s personal UW page

Principal Investigator

Kurt Weaver is an Assistant Professor in the Department of Radiology and holds faculty affiliations in the UW Graduate Program in Neuroscience, the UW Center for Sensorimotor Neural Engineering (CSNE) and an adjunct appointment in the UW Department of Psychology. He is a junior Investigator in the grid lab and a primary instructor in the UW School of Medicine where he is co-director of the Mind, Brain and Behavior block, the primary neuroanatomy course for UW undergraduate medical education. His research interests are primarily focused on the relationship between complex and integrative neural systems and higher-level cognitive and behavioral function. Current efforts combine both functional imaging (e.g. fMRI) modalities and invasive electrophysiology including Electrocorticography (ECoG) and Deep Brain Stimulation (DBS) to probe cognition as a function of interactions across widely distributed yet highly inter-connected networks. This work leverages the high fidelity of direct recordings from the human cortex and deep brain structures to interrogate relationships between brain organization, functional connectivity and computation neurophysiology.

Principal Investigator

Dr. Jason S. Hauptman is an associate professor of neurological surgery and a board-certified pediatric neurosurgeon. He is a staff neurosurgeon at both Seattle Childrens Hospital and Harborview Medical Center. He dedicates a significant portion of his clinical practice to the surgical management of epilepsy, both in children (Seattle Children’s Hospital) and adults (Harborview Medical Center). For the surgical management of epilepsy, he focuses on the utilization of stereoelectroencephalography (sEEG) including using the ROSA Robotic System, stereotactic laser thermoablation (LITT), neuromodulation such as VNS and RNS, and open surgery such as lobectomy, hemispherectomy, and corpus callostomy. Dr. Hauptman also has a clinical interest in the surgery of tumors involving eloquent cortex, using techniques such as fMRI/rsfMRI planning and awake functional mapping. His research focuses on translation of novel therapeutics to the bedside, including targeted molecular therapies for epilepsy, as well as patient-oriented approaches to improve outcomes in epilepsy and pediatric neurosurgery.
