Prior to becoming a specialist neuroradiologist, Dr. Mahammedi completed a Neuroradiology fellowship at the Cleveland Clinic Imaging Institute after having completed residencies in both Nuclear Medicine and Diagnostic Radiology. His specialty interests include brain tumors, stroke, small vessel disease, head and neck imaging, and functional magnetic resonance imaging (fMRI). Dr. Mahammedi has contributed to over 30 peer-reviewed publications, including lead authoring multiple articles in high-impact journals. During the beginning of the COVID-19 pandemic, he led and collaborated with multiple institutions from Italy, Spain, and Brazil. His work was considered the first and largest study in the literature that systematically characterized neurological symptoms and neuroimaging features in hospitalized COVID-19 patients, which was published in the journal Radiology. Recently, he has published the most recent multicenter and global COVID-19-related articles, which were featured by the international media in more than 25 languages including 200 newspapers, CNN, BBC, NPR, local televised broadcasts, and the 2020 RSNA Press Release. He co-authored multiple books, including “Imaging Appearance of Migraine and Tension Type Headache” and "Humanizing BrainTumors: Strategies for You and Your Physician" which was published in 2022. Dr. Mahammedi has received numerous awards and honors, including being selected as a semi-finalist for the prestigious Cornelius Dyke Award of the American Society of Neuroradiology (ASNR) 2021, and Best Case Award at the American Institute of Radiologic Pathology (AIRP) in Neuroradiology. In 2014, he was recognized as one of the authors with top-cited articles for his work in the Journal of Thoracic Imaging at the Society of Thoracic Imaging (STR) meeting, where he introduced a new technique for early detection of pulmonary hypertension on CT scans.

Cormac Maher, MD, FAANS, FAAP, FACS
Botha Chan Endowed Professor
BioDr. Maher is a board-certified, fellowship-trained neurosurgeon with Stanford Health Care and is chief of neurosurgery at Lucile Packard Children’s Hospital Stanford. He is also the Botha Chan Endowed Professor in the Department of Neurosurgery, Division of Pediatric Neurosurgery at Stanford University School of Medicine.
Dr. Maher specializes in treating children who have neurological disorders — conditions of the brain, spinal cord, and nerves. In his adult practice, he offers particular expertise in treating Chiari malformation, which involves a portion of the brain pushing down into the spinal canal, and tethered spinal cord. Dr. Maher has served on many national organization committees for research and training in neurosurgery.
Dr. Maher has published more than 190 articles in peer-reviewed journals, including Journal of Neurosurgery, Neurosurgery, and Journal of Neurosurgery: Pediatrics. He has also served on the editorial boards for publications and organizations including the Journal of Neurosurgery Publishing Group. He has performed ad hoc review for many other journals and grant review for organizations including the American Association of Neurological Surgeons (AANS).
Dr. Maher has delivered hundreds of presentations at symposiums and conferences for national and international audiences. He is also a fellow of the American Academy of Pediatrics, AANS, and American College of Surgeons. -
Nazanin Mahinparvar
Postdoctoral Scholar, Anesthesiology, Perioperative and Pain Medicine
BioNazanin Mahinparvar, MD, graduated from Isfahan University of Medical Sciences in Iran. Before joining Stanford, she spent three years as a Physician Director at a rehabilitation and long-term care center for older adults. Caring for patients with pain, mobility limitations, and loss of independence shaped her belief that medicine is not only about treating disease, but also about helping people preserve function, independence, and quality of life.
She later joined the Dr. David Yeomans Lab, Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University School of Medicine as a postdoctoral scholar, where her research has focused on developing novel, non-opioid approaches for chronic pain. Having personally experienced chronic pain during adolescence, she understands how deeply persistent pain can affect movement, daily function, and quality of life. Studying pain at Stanford transformed that personal understanding into a professional mission: not simply to reduce pain, but to help people regain function and return to meaningful, active lives.
Art and movement have deeply influenced the way she sees medicine. Through playing the piano, painting, dancing, ice skating, swimming, and exercise, she has developed a strong appreciation for the connection between movement, coordination, precision, creativity, and human performance. To her, restoring function is about more than restoring movement—it is about helping people return to the activities, passions, and forms of expression that are meaningful to them.
Leadership, education, and mentorship are also central to her academic work. As a Faculty Educator and instructor for the Stanford Microsurgery Fall Internship through the Stanford Anesthesia Summer Institute (SASI), she brings together medicine, art, and education by incorporating art-inspired exercises into microsurgical training to develop fine motor control, hand-eye coordination, precision, and dexterity. She is passionate about creating engaging learning experiences and inspiring the next generation of learners in medicine.
Together, her experiences in rehabilitation, pain medicine, education, movement, and art ultimately led her to Physical Medicine & Rehabilitation (PM&R), where these interests naturally come together. She is particularly interested in interventional pain, musculoskeletal and Sport medicine, and the intersection of rehabilitation with movement and human performance. Her goal is to build a clinical and academic career focused on restoring function, improving quality of life, and helping people return to what matters most to them. -
Sally Mahmoud-Werthmann
Clinical Assistant Professor, Emergency Medicine
Current Research and Scholarly InterestsDr. Mahmoud-Werthmann's research focuses on implementation science, health equity, and healthcare delivery innovation, with an emphasis on improving care for patients experiencing social and structural barriers to health. She is particularly interested in understanding how evidence-based interventions can be effectively implemented, adapted, and scaled within real-world healthcare settings to improve access, quality, and outcomes for vulnerable populations.
A central theme of her work is centering the experiences of patients and communities in the design of healthcare interventions. She has a strong interest in qualitative and mixed-methods research and values approaches that elevate patient perspectives, identify barriers to care, and inform the development of more responsive healthcare systems. Her current work includes qualitative research exploring telehealth access and utilization among unstably housed populations, with a particular focus on co-designing potential solutions alongside patients and community stakeholders.
Her research also includes evaluation of community health worker programs, implementation strategies to increase adoption of evidence-based addiction treatment, including emergency department naltrexone prescribing, and operational approaches to addressing health-related social needs within healthcare systems. More broadly, she is interested in developing and evaluating scalable models that improve care transitions, strengthen system navigation, and advance health equity across the continuum of care.
In addition to her health services and implementation research, Dr. Mahmoud-Werthmann is interested in advancing equity within academic medicine. Her work in this area focuses on understanding barriers to advancement for women in emergency medicine and exploring innovative models of mentorship, sponsorship, and professional development that promote equitable career advancement and leadership opportunities.
