Grace was initially raised in the United Kingdom and then in Nigeria where she trained as a primary care physician. During her training, her rotations were spread across many fields of medicine where she learned to manage the overall wellbeing of families. She often worked with non-governmental organizations (NGOs) that helped fund healthcare resources as they served patients in the local villages that could not afford to travel or pay for healthcare. To her this was very gratifying as it geared her thoughts towards public health. This interest led her to obtain her master’s degree in public and global health from New York Medical College about 9 years ago. Overall, her diverse interactions with patients of all age groups have taught her the importance of humility, sacrifice, hard work and creativity. This also gave her insight to explore other ways of building her knowledge through research as those were resources not available in her home country.
Grace joined the Movement Disorders team at MGH in 2007 as a research coordinator where she had the opportunity to focus her time and energy on the care of patients with Parkinson’s Disease. She has coordinated a variety of PSG studies which has given her the opportunity to serve and build great relationships with patients, their families, other study coordinators, monitors and other executive committee members. She currently serves as a Senior Clinical Research Coordinator at MGH, the coordinator for the Parkinson’s Foundation Center of Excellence, and also as a visiting primary care physician in my home country aiding patients that do not have access to healthcare. Being involved with the PSG has given me the opportunity to participate in research studies with which she is proud to be associated, and to learn from many mentors and colleagues.

Dr. Jimenez-Shahed is an Associate Professor of Neurology and Medical Director, Movement Disorders Neuromodulation and Brain Circuit Therapeutics. After completing her undergraduate degree at Washington University in St. Louis, Dr. Jimenez-Shahed received her medical degree from Baylor College of Medicine (BCM) and Neurology residency training at Duke University Medical Center. She then completed a fellowship in Movement Disorders at the Parkinson’s Disease Center and Movement Disorders Clinical (PDCMDC) at BCM. Her research interests lie in investigating the intraoperative neurophysiology of patients undergoing deep brain stimulation (DBS) for movement disorders and the application of wearables and digital health technologies to the care of patients with Parkinson’s disease.
Dr. Jimenez-Shahed joined the PSG fresh out of fellowship in recognition of the networking opportunities it afforded as well as the chance to participate in the latest important clinical research in Parkinson’s disease (PD). As her professional interests developed in the arena of neuromodulation, she sought to develop her ideas within the Functional Neurosurgical Working Group (FNSWG).
As Co-Chair and Chair of the FNSWG, along with her co-I Jim McInerney, she established RAD-PD (Registry for the Advancement of Deep Brain Stimulation in Parkinson’s disease). Funded by MJFF, it is the first official study and database established within the FNSWG. Other FNSWG activities under her leadership have included shepherding several projects to publication or presentation at national meetings and formation of a Neuropsychology Focus Group.
Her additional service to PSG has included serving on the Credentials committee and Nominations committee, mentorship of junior members, and faculty participation at the PSG CME program from 2018-2020. Dr. Jimenez-Shahed has had varied roles in clinical trials over her career including: PI for several DBS investigator-initiated studies; Site Principal Investigator in multiple clinical trials across a variety of movement disorders; Site co-I, sub-I or rater for many more clinical trials; Key Advisor and Opinion Leader for Industry-sponsored trials; Development and implementation of a rater training program for an international clinical trial.
As a result of these activities, she is not only knowledgeable about clinical trials and research, but also about PSG infrastructure and resources, and the multi-faceted benefits the PSG offers to members.

Dr. Willis is an Associate Professor of Neurology and of Epidemiology (with tenure), a Senior Scholar in the Center for Clinical Epidemiology and Biostatistics, a Senior Fellow at the Leonard Davis Institute of Health Economics, and a Faculty Scholar at the Center for Pharmacoepidemiology Research Training at the University of Pennsylvania (UPenn) School of Medicine. She is also the Co-Director of the UPenn Resource Center for Minority Aging Research.
Upon completing an adult neurology residency at the Washington University School of Medicine, Dr. Willis pursued a clinical fellowship in movement disorders and a research training program focused on analytical epidemiology, biostatistics, geographical information systems (spatial epidemiology), pharmacoepidemiology, and health outcomes research (culminating in a Master of Science in Clinical Investigation). She uses analytical epidemiology methods to pursue research questions relevant to clinical decision-making and health policy for neuroimaging populations through two complementary investigative paths. Her health services research program focuses on the complex ways patient factors (such as race, sex, comorbid disease, and geographical location) affect the interactions older adults with neurological diseases have with the U.S. healthcare system. Her pharmacoepidemiology research program focuses on the bidirectional relationships between neurological disease and CNS drug effects- such as whether neurological disease predisposes to specific adverse drug reactions and whether CNS-acting drugs influence neurological disease phenotype or progression.
Dr. Willis has been privileged to serve in several roles in the PSG since joining as a fellow, including Co-Chair of the Healthcare Outcomes and Disparities Working Group, Member of the Mentoring Committee, and Member of the Nominating Committee. She has also enjoyed and benefited from the research, collaboration, and mentoring opportunities made possible through the PSG at every stage of her career to date. As a fellow/ junior faculty member of the PSG, she has benefitted from PD-focused career development sessions at PSG meetings and learned to affectionately call herself a “Parkinsonologist.” Her cross-training and cross membership in the neurology, epidemiology, aging, and health services research communities requires that she communicate her research credibly for use by multiple stakeholders, varied audiences. Through formal and informal speaking opportunities at the PSG, she learned (and continues to learn) how to communicate her research for use by the academic PD community. Throughout Dr. Willis’s career, PSG members have guided and shaped her research ideas into work with the potential to advance our scientific conversations about health outcomes and disparities in Parkinson disease populations. Finally, the PSG has provided her with multiple opportunities to pursue her favorite teaching activity- mentoring, and has led to successful research collaborations, valued personal and professional connections.
