The George Lab Research Team

George Lab


Paul George, MD, PhD
Assistant Professor of Neurology & Neurological Sciences

Paul grew up in Tennessee. He obtained his BSE from Tulane University and subsequent masters at Johns Hopkins in biomedical engineering.  He then joined the Health Sciences and Technology program where he obtained a PhD in Medical and Electrical Engineering in Dr. Robert Langer’s lab at MIT and his MD from Harvard.  After this, he journeyed out west to Stanford for his medical training and joined the Neurology faculty in 2016 as an Assistant Professor. His main focus is working with physicians, neuroscientists, and engineers to improve the care of stroke patients and neural recovery through his lab’s research as well as his clinical service.

Byeongtaek  Oh
Postdoctoral Fellow

Byeongtaek is a postdoctoral fellow in the Department of Neurology and Neurological Science at Stanford University School of Medicine. In 2011 he started his PhD degree in Pharmaceutical Science at the University of Missouri under the guidance of Dr. Chi H. Lee. His thesis focused on the development of polymeric and carbon-based nanomedicine for the effective drug and stem cell delivery methods against atherosclerosis. He was awarded his PhD in 2016 and joined the George group in July 2016.

Dr. Oh continued material science and stem cell research as a postdoctoral fellow at Stanford University where he leads a project designing biocompatible and implantable conductive scaffolds for neural progenitor cell treatment of stroke in Dr. George’s lab. His approach evaluates the regulation of hNPCs and their paracrine effects via electrical stimulation.

Shang Song
Postdoctoral Fellow

Shang is a postdoctoral fellow in the Department of Neurology and Neurological Science at Stanford University. She received her BS with honors in Biomedical Engineering from Brown University, and her PhD from the Joint Graduate Program in Bioengineering at University California, Berkeley and San Francisco. Her graduate work focused on the development of bioartificial organs and study of interaction between stem cells and biomaterials with engineering and molecular techniques in Dr. Shuvo Roy’s lab. Dr. Song joined the George lab in June 2017. She currently investigates the effect of electrical stimulation in augmenting stem cell therapy for nerve regeneration. Particularly, she is interested in studying how neural progenitor stem cells are influenced by electrical stimulation for better functional recovery in animal models.

Alexa Levinson
Lab Manager/Research Assistant

Alexa Levinson received her Bachelor of Science from Tulane University in 2016. Her undergraduate research pursued multiple disciplines from neurogenetics to bioengineering. Alexa’s desire to further challenge herself coupled with her passion for biomedical research and engineering brought her from the south to the George lab in June 2016. Currently Alexa is trying to improve stroke recovery using engineered neural progenitor cells. To validate the efficacy of the paracrine effects on a stroke model, Alexa performs immunostaining and various molecular techniques to look deep inside the brain and determine the micro-cellular effects of a stroke. In addition, Alexa is studying how stem cells, influenced by electrical stimulation, effect glioblastoma treatment.

Vivek Lam
Undergraduate Researcher

Vivek is an undergraduate researcher at Stanford majoring in Chemical Engineering. His curiosity to develop stem cell delivery systems brought him to the George Lab where the lab utilizes interdisciplinary approaches of chemistry, bioengineering and electrical engineering. Vivek designs novel conductive scaffolds for neural regeneration with an approach consisting of observing how various electrical parameters and material characteristics influence stem cell phenotypic changes and improve the efficacy of stem cell therapeutics.

Neha Srivathsa
Undergraduate Researcher

Neha Srivathsa is a sophmore undergraduate researcher at Stanford University, and is from Bangalore, India. She is intrigued by interdisciplinary approaches to solving pertinent problems and is currently exploring interests in biomaterials and regenerative medicine. She hopes to pursue a career in research to help democratise healthcare. Outside of lab, she is a martial arts enthusiast and Indian classical dancer.

Vishal Swaminathan
Visiting Researcher

Vishal is a medical school student in the Sidney Kimmel Medical College at the Thomas Jefferson University. He completed his undergraduate studies as a part of the accelerated medical program at The Pennsylvania State University, where he conducted research on potential treatments for Alzheimer's disease. His interest in brain injury and neurodegenerative disorders brought him to the George Lab, where the use of conductive scaffolds is being tested as a possible therapy for ischemic stroke. Vishal studies the paracrine effects of electrically stimulated iPSC's and hNPC's, the extent of functional recovery in animal models treated with the conductive scaffold, and various factors that influence the efficacy of stem cell differentiation into neurons and glial cells. He has a strong interest in regenerative medicine and firmly believes stem cell therapeutics will have a profound impact in the field of neurology.
