Dr. Doris Wang is a neurosurgeon who specializes in surgery for patients with movement disorders, such as essential tremor, Parkinson's disease and dystonia, a condition in which involuntarily contracting muscles cause abnormal movements.
Wang uses deep brain stimulation devices – implantable devices that can send electric signals to specific areas of the brain – in her research to better understand the dynamics of neural networks that develop as humans learn motor skills. Her goal is to develop targeted treatments that restore motor skill learning in patients with brain diseases and injuries.
Wang earned her doctorate in neuroscience and her medical degree at UCSF, where she also completed a residency in neurosurgery. During her residency, she developed an interest in functional neurosurgery, which utilizes a variety of techniques to restore or improve brain function. Also at UCSF, she completed a fellowship in stereotactic and functional neurosurgery, which involves using advanced imaging techniques such as computed tomography and magnetic resonance imaging to guide neurosurgical procedures.
A member of the UCSF community since 2004, Wang shares the institution's values and commitment to advancing patient care while deepening scientific understanding of neurological disorders. She belongs to the Congress of Neurological Surgeons, American Association of Neurological Surgeons and American Society for Stereotactic and Functional Neurosurgery.

Huiling Tan is the Professor of Human Electrophysiology and Neuromodulation at the University of Oxford, a Medical Research Council (MRC) Investigator and Programme Leader, and a Turing Fellow at the Alan Turing Institute, UK.
Professor Tan has made significant contributions to understanding how abnormal brain activity leads to the debilitating symptoms of movement disorders such as Parkinson’s disease. Leveraging this knowledge, her research group designs and tests cutting-edge closed-loop neuromodulation approaches in patients with movement disorders. Her work is driven by the hypothesis that neuromodulation strategies tailored to underlying brain circuit pathophysiology are more effective and carry fewer side effects than conventional continuous stimulation.
Throughout her career, Professor Tan is dedicated to fostering an open, supportive, and motivating environment for young scientists in her team and beyond. She is widely recognized for mentoring and empowering early-career scientists, helping to shape the next generation of leaders in neuroscience and neuromodulation.

Dr. Germann is a scientist and Principal Investigator at the Krembil Research Institute, University Health Network, in Toronto, Canada. His research program focuses on brain mapping and computational modelling to investigate the neural correlates of typical and atypical thought processes. Drawing on a range of imaging modalities—including structural, functional, diffusion, and other physiological imaging data—he identifies large-scale brain networks involved in cognition, emotion, and behaviour.
A major focus of Dr. Germann’s work is understanding how these networks are disrupted in neurodegenerative diseases of aging, such as Parkinson’s disease, as well as in psychiatric conditions like depression and obsessive-compulsive disorder. His research combines neuroimaging with computational approaches to develop more precise biomarkers and support personalized treatment strategies. Ultimately, his goal is to improve diagnosis, optimize interventions, and contribute to more effective, patient-centered care.
