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. -
Rebecca Tarlau
Associate Professor in the Graduate School of Education
BioRebecca Tarlau is Associate Professor of Education at Stanford Graduate School of Education. Dr. Tarlau was formerly Associate Professor of Education and of Labor and Employment Relations at the Pennsylvania State University, where she was the co-founder of the Penn State Consortium for Social Movements and Education Research and Practice. Her ethnographic research agenda has four broad areas of focus: (1) theories of the state and state-society relations; (2) social movements and popular education, labor education, and critical pedagogy; (3) Latin American education and development; and (4) teachers’ unions, teacher activism, and teachers’ work.
Dr. Tarlau is the author of the award-winning Occupying School, Occupying Land: How the Landless Workers Movement Transformed Brazilian Education (2019, Oxford University Press, published in Portuguese in 2023 by Expressão Popular), which analyzes how a large grassroots social movement has linked education reform to its vision for agrarian reform by developing pedagogical practices for schools that foster activism, direct democracy, and collective forms of work. Contrary to the belief that social movements cannot engage the state without demobilizing, Tarlau shows how educational institutions can help movements recruit new activists, diversify their membership, increase technical knowledge, and garner political power. Dr. Tarlau’s forthcoming book Teacher Organizing Across the Americas: Diverse Strategies for Transforming Unions, Schools and Societies (Oxford University Press) explores why teachers’ unions in Brazil, Mexico, and the United States have embraced radically different strategies, and the important role of internal oppositional movements in transforming the goals and strategies of labor unions. Currently Dr. Tarlau is involved in a multi-country comparative study analyzing the impact of sustainable agriculture education on agroecological knowledge and landscape change in Latin America. -
William Abraham Tarpeh
Assistant Professor of Chemical Engineering, by courtesy, of Civil and Environmental Engineering and Center Fellow at the Precourt Institute for Energy and, by courtesy, at the Woods Institute for the Environment
BioReimagining liquid waste streams as resources can lead to recovery of valuable products and more efficient, less costly approaches to reducing harmful discharges to the environment. Pollutants in effluent streams can be captured and used as valuable inputs to other processes. For example, municipal wastewater contains resources like energy, water, nutrients, and metals. The Tarpeh Lab develops and evaluates novel approaches to resource recovery from “waste” waters at several synergistic scales: molecular mechanisms of chemical transport and transformation; novel unit processes that increase resource efficiency; and systems-level assessments that identify optimization opportunities. We employ understanding of electrochemistry, separations, thermodynamics, kinetics, and reactor design to preferentially recover resources from waste. We leverage these molecular-scale insights to increase the sustainability of engineered processes in terms of energy, environmental impact, and cost.

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.

Christopher John Tassone
Associate Professor (Research) of Photon Science
BioChristopher J. Tassone, PhD is the Associate Lab Director for the Energy Sciences Directorate. His scientific interests lie in the development and characterization of advanced materials for energy. Dr. Tassone’s research addresses critical challenges in energy transition materials, plastics production, and catalysis, with the goal of improving energy technologies and utilizing domestically secure feedstocks. He is an expert in synchrotron-based X-ray scattering techniques, which he uses to probe the time resolved structure of materials as they are synthesized, and how they evolve under operation. He compliments this focus on developing operando and in-situ methods, with the development and application of machine learning for data interpretation and experimental steering. Through this work, Dr. Tassone helps accelerate the discovery of innovative materials for energy and catalysis.

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.
