Medical Advisory Board
The Medical Advisory Board provides clinical leadership and strategic oversight to ensure the highest standards of patient care, safety, and regulatory compliance. Serving as a bridge between medical practice and organizational
operations, the Medical Board guides clinical policies, supports research & development, and helps align products with the latest evidence-based practices.
Phyllis Sirotta Feldman, M.D.
Chairman
A natural trailblazer in medicine, Dr. Feldman is the Chairman of the Medical Advisory Board, where she leads the board in overseeing, among many other things, strategy, research and development, quality control, and long-term value creation. With over 40 years of experience in healthcare, Dr. Feldman brings a unique expertise. She is well regarded throughout the US, earning numerous accolades for her quality and patient-centered care.
Dr. Feldman is Board Certified by the American Board of Psychiatry and Neurology. She brings expert training from the Virginia Commonwealth University School of Medicine, the University of North Carolina at Chapel Hill School of Medicine and a compassionate, individualized approach to care.
Vishal Yajnik, M.D., M.S.
Dr. Yajnik is a physician-leader working at the intersection of anesthesiology and critical care, where clinical practice meets device and process innovation. He serves as an Associate Professor of Anesthesiology and Neurosurgery, Medical Director of the Neuroscience Intensive Care Unit, as well as Section Chief of Neurocritical Care in Anesthesiology at VCU Health.
His training reflects a longstanding interest in the mechanisms underlying critical illness. He holds a foundation in public health from Johns Hopkins University, advanced training in physiology and biophysics from Georgetown University, and an M.D. from the VCU School of Medicine. He completed his anesthesiology residency at VCU Medical Center and a critical care fellowship at the University of
Pittsburgh Medical Center.
Dr. Yajnik’s work extends beyond the bedside to the tools and systems that shape care delivery. He has focused on biomedical innovation as a route to patient safety — identifying the gaps where clinicians compensate by hand for problems that better-designed equipment could solve and developing solutions that hold up under the realities of clinical workflow. The SAM device grew directly out of that approach.
D. Joshua Cohen, M.D.
Dr. Cohen is a Research Assistant Professor in the Department of Biomedical Engineering at Virginia Commonwealth University; a nationally recognized public research institution committed to innovation and community well-being.
As a member of the Laboratory for Musculoskeletal Research and Innovation (LMRI), Dr. Cohen works at the forefront of interdisciplinary science, exploring the biological control and physiological synthesis of bone, cartilage, and skeletal muscle across in vitro, in vivo, and translational models.
Embedded within VCU’s Institute for Engineering and Medicine, Dr. Cohen collaborates with trainees at all levels to advance discoveries that bridge engineering and human health, driving forward the future of musculoskeletal research.
