Neurosurgery Clinical Instructors

Geoff Appelboom, MD, PhD
Radiosurgery and Image Guided Neurosurgery

Geoff Appelboom, MD PhD is a clinical instructor in the Department of Neurosurgery at Stanford. Dr Appelboom received is medical degree from ULB School of Medicine where he also completed his residency in Neurological Surgery.  He spent 3 years of integrated research fellowship at Columbia University Medical Center in New York studying genetic predictors of vascular fragility.  Geoff has also completed a master in stereotactic surgery at La Sorbonne University in Paris. 

He now focuses his interest on image-guided surgery of tumors of the brain and spine, vascular malformations and pain. His current research explores stereotactic disruption of the blood-brain barrier for drug delivery as well as radiosurgery for psychiatric disorders.


Andy Stadler, MD
Pediatric Neurosurgery


Jonathan Liu, MD
Cerebrovascular Neurosurgery

Jonathan Liu, a Chicago native, completed his medical training at the Chicago Medical School, followed by an Internship and Neurosurgery residency at University of California-Davis where he completed an infolded spine fellowship in 2014, and served as chief resident 2015-2016.  His current research interests include cerebral revascularization and treatment of cerebrovascular disorders.  Dr. Liu is looking forward to completing a skull base neurosurgery fellowship at Swedish Neuroscience Institute 2017-2018.

Justin Murray Moore, MD (Hon), PhD, LLB, B.Med.Sci (Hon), Grad Dip Surg Anatom, FRACS (Neurosurgery)

Specialty: Surgical Neuro-Oncology Skull Base Fellow

Justin Moore completed B.Med.Sci and Medical degrees at Monash University in Melbourne, Australia under a faculty scholarship and obtained first class honors in both. Justin also completed a law degree with an emphasis on medical law. He completed his intern year and basic surgical training at St Vincent’s Hospital in Melbourne, Australia while obtaining a post-graduate diploma in surgical anatomy from Melbourne University. Justin was awarded a scholarship to Oxford University in the UK, where he completed a PhD in neuro-genomics, which focused on novel genes involve in neurodevelopment and tumor formation. Justin then returned to Australia and completed residency training in Neurosurgery, training at numerous hospitals including The Alfred, Monash and Royal Melbourne Hospitals before being awarded a fellowship of Royal Australasian College of Surgeons. He has just completed a cerebrovascular fellowship at BIDMC, Harvard Medical School in the USA. He has active research interests in cerebrovascular neurosurgery, neuro-oncology and the interaction between the law and neurosurgery.


Johnny Ho Yin Wong, MD PhD, MMed (Clin Epi), FRACS (Neurosurgery)
Interventional Neuroradiology

Johnny Wong completed medical school in Sydney, Australia, graduating with honours from University of New South Wales in 2002. He completed neurosurgical training at multiple hospitals in Sydney including Royal Prince Alfred Hospital, Prince of Wales, St Vincent's and Macquarie University Hospital, and was awarded his fellowship qualifications through the Royal Australasian College of Surgeons in 2013. He completed his PhD at Macquarie University, with a thesis titled: "Post-traumatic syringomyelia: Investigations into pathophysiology". Since completing his neurosurgical training, he undertook subspecialty fellowship in open cerebrovascular surgery at Toronto Western Hospital (University of Toronto). He has been a clinical instructor in interventional neuroradiology at Stanford since 2015. His research interests include: cerebral and spinal vascular disorders, syringomyelia and CSF fluid dynamics.  


Matthew MacDougall, M.D.
Functional Neurosurgery

Matthew MacDougall, a San Diego native, became interested in the brain and its dysfunction at a young age. On a path to satisfy this curiosity, he earned a B.S. summa cum laude from Emory university before undertaking medical studies at USC and conducting research at Caltech in brain machine interface and protein design. Finishing his M.D. degree in 2009, he matched at UCSD in the neurosurgery program, where he was the first to achieve optical control of brain activation in marmosets. During his fellowship in functional neurosurgery at Stanford, Dr. MacDougall is conducting research on brain machine interfaces.
