Ludy Shih


Dr. Shih has research interests in tremor and gait disorders in Parkinson’s disease (PD) and related movement disorders and their intersection with cognitive impairment and aging. She is interested in developing digital motor signatures, and has applied quantitative techniques to studying movement in both healthy and clinical populations, such as those who receive interventions such as deep brain stimulation (DBS) for PD and essential tremor (ET). Her work includes the use of wearable sensors and other objective methods to assess and characterize tremor, gait and related neurologic impairments in order to develop clinical and translational tools for detecting and managing these impairments. In addition, she is interested in the use of technology to improve access to care for vulnerable aging individuals with motor and cognitive impairment. Her investigator-initiated work has been funded by the Michael J. Fox Foundation and the Consortia for Improving Medicine with Innovation and Technology (CIMIT).

She has completed a Master’s degree in Clinical Investigation from the Harvard-MIT Health Sciences and Technology Clinical Investigator Training Program in collaboration with Pfizer and Merck & Co. While working in In biotech and pharma, she worked on multi-disciplinary teams on biomarker (fluid, imaging and wearable sensors), epidemiology, and natural history studies. Primarily focused on research and early development, she led clinical study design for several phase 1 and phase 2 studies, including the evaluation and selection of outcome assessments, including biomarker assessments and biostatistical innovation into protocol development, and was responsible for overall study execution and oversight. In addition, she has experience with both US and EU regulatory agency interactions, academic-industry partnerships through scientific collaborations, and evaluated external assets for in-licensing.

She currently serves on the Medical Advisory Board for the International Essential Tremor Foundation (IETF), the International Parkinson’s Disease and Movement Disorders Society (MDS) Tremor Study Group and previously served on the Steering Committee for the Registry for Advancement of Deep Brain Stimulation Therapy for Parkinson’s Disease (RAD-PD). She is a member of the Parkinson Study Group (PSG), Tremor Research Group (TRG), the MDS, and is a fellow of the American Academy of Neurology (AAN) and of the American Neurological Association (ANA).
