Dr. Raslan

Ahmed Raslan, M.D., Principal Investigator

In 2004, Raslan joined OHSU as a neurosurgical instructor. Already a fully qualified neurosurgeon (Ain Shams University in Egypt), in 2012 he completed the OHSU neurological surgery residency program (required for practice in the US). Dr. Raslan joined the faculty of neurological surgery in July 2012 as an assistant professor and was promoted to associate professor in 2017.

Dr. Raslan's research is focused on  the cortical and subcortical physiology, physiology of nociception and pain modulation, pathophysiology of trigeminal neuralgia, outcomes of functional neurosurgery, functional localization using intraoperative and extraoperative mapping, surgical education and operative efficiency.

Dr. Raslan's research interests parallel his clinical interests and reflect his values. He also believes in scientific discovery that addresses healthcare disparities.

Caleb Nerison, B.A., B.S., Research Fellow, 2021-2022

Western University of Health Sciences, College of Osteopathic Medicine of the Pacific-NW. Doctor of Osteopathic Medicine Candidate, 2024

Caleb is the current research fellow for the Raslan lab and a Doctor of Osteopathic Medicine Candidate at Western University of Health Sciences, College of Osteopathic Medicine of the Pacific-NW. Caleb is actively working to build on the foundational research endeavors of the previous research fellows. He has been invaluable in navigating information technology requirements needed for extremely large cognitive data sets (collection, analysis and sharing).

Joseph G. Nugent, B.A., M.H.S., Student Volunteer

MD/MPH Candidate, Class of 2023

Joe has been an active and contributing member of the Raslan Lab since his first months as a medical student at OHSU in 2018. He is pursuing a joint degree in medicine and public health through the OHSU-PSU School of Public Health with a concentration in Epidemiology and Biostatistics. Joe’s research interests center around the spectrum of traumatic brain injury, from population-level trends in incidence and mechanisms, to neurocritical care, brain mapping, and neurophysiology with a particular interest in electrophysiologic factors predicting capacity for functional recovery. Joe also holds interest in advanced biostatistical and epidemiologic methods, and continues to actively participate in endeavors focusing on medical education, integration of multimodality intraoperative mapping mechanisms, as well as health disparities and inequities.
