Sami Gamal-Eldin Tantawi
Professor of Particle Physics and Astrophysics, Emeritus
BioFor over a decade I have advocated for dedicated research efforts on the basic physics of room temperature high gradient structures and new initiatives for the associated RF systems. This required demanding multidisciplinary collaboration to harness limited resources. The basic elements of the research needed to be inclusive to address not only the fundamentals of accelerator structures but also the fundamentals of associated technologies such as RF manipulation and novel microwave power sources. These basic research efforts were not bundled with specific developments for an application or a general program. The emerging technologies promise a broad, transformational impact.
With this underlying philosophy in mind, in 2006 the US High Gradient Research Collaboration for which I am the spokesman was formed. SLAC is the host of this collaboration, which comprises MIT, ANL, University of Maryland and University of Colorado, NRL and a host of SBIR companies. This led to the revitalization of this research area worldwide. The international collaborative effort grew to include KEK in Japan, INFN, Frascati in Italy, the Cockcroft Institute in the UK, and the CLIC team at CERN.
This effort led to a new understanding of the geometrical effects affecting high gradient operations. The collaborative work led to new advances in understanding the gradient limits of photonic band gap structures. Now we have a new optimization methodology for accelerator structure geometries and ongoing research on alternate and novel materials. These efforts doubled the usable gradient in normal conducting high gradient linacs to more than 100 MV/m, thus revitalizing the spread of the technology to other applications including compact Inverse Compton Scattering gamma-ray sources for national security applications, and compact proton linacs for cancer therapy. -

Peter Tass
Professor of Neurosurgery
BioDr. Peter Tass investigates and develops neuromodulation techniques for understanding and treating neurologic conditions such as Parkinson’s disease, epilepsy, dysfunction following stroke and tinnitus. He creates invasive and non-invasive therapeutic procedures by means of comprehensive computational neuroscience studies and advanced data analysis techniques. The computational neuroscience studies guide experiments that use clinical electrophysiology measures, such as high density EEG recordings and MRI imaging, and various outcome measures. He has pioneered a neuromodulation approach based on thorough computational modelling that employs dynamic self-organization, plasticity and other neuromodulation principles to produce sustained effects after stimulation. To investigate stimulation effects and disease-related brain activity, he focuses on the development of stimulation methods that cause a sustained neural desynchronization by an unlearning of abnormal synaptic interactions. He also performs and contributes to pre-clinical and clinical research in related areas.

Pahnwat Tonya Taweesedt, MD
Clinical Instructor, Psychiatry and Behavioral Sciences - Sleep Medicine
BioDr. Pahnwat Taweesedt is a board-certified, fellowship-trained sleep specialist at Stanford Health Care. She is also a clinical instructor in the Department of Psychiatry and Behavioral Sciences, Division of Sleep Medicine at Stanford University School of Medicine.
Dr. Taweesedt specializes in diagnosing and treating sleep disorders such as obstructive sleep apnea (OSA) and central sleep apnea (CSA). She also treats obesity hypoventilation syndrome, a condition that causes breathing issues during sleep.
Her research focuses on sleep technology, the relationship between sleep and neurodevelopmental disorders, and sleep in the aging population. She has also studied medications for narcolepsy (a disorder that affects the brain’s ability to control sleep-wake cycles).
Dr. Taweesedt has contributed chapters to a variety of medical textbooks, including “Advances in Health and Disease” and “Vasculitis: From Diagnosis to Treatment.” She also serves as a reviewer for several peer-reviewed research journals, including Sleep Science and Practice, Healthcare, and Journal of Autism and Developmental Disorders.
Dr. Taweesedt is a member of the American College of Chest Physicians, American Thoracic Society, Sleep Tracker Task Force of World Sleep Society, and American Academy of Sleep Medicine. -
Daniel Tawfik
Assistant Professor of Pediatrics (Critical Care)
Current Research and Scholarly InterestsThe Tawfik lab studies the use of electronic health record metadata in identifying structures and processes that promote high quality healthcare. Our projects apply advanced analytical methods to large databases of primarily structured electronic health record data and EHR usage metadata.

Vivianne Tawfik
Associate Professor of Anesthesiology, Perioperative and Pain Medicine (Adult Pain)
Current Research and Scholarly InterestsMy overall research interest is to understand how the immune system interacts with the nervous system after injury to promote the transition from acute to chronic pain. In my clinical practice I care for patients with persistent pain that often occurs after minor trauma such as fracture or surgery. Using basic science approaches including whole system immune phenotyping with mass cytometry and genetic manipulation of peripheral and central immune cells, we seek to dissect the temporal and tissue-specific contribution of these cells to either promotion or inhibition of healing.
