Mary Hawn, MD, FACS
Emile Holman Professor of Surgery
Current Research and Scholarly InterestsMy area of research is health services researcher focusing on surgical quality measurement and policy. I have a background and training in epidemiology coupled with my leadership roles in surgical quality measurement. My expertise and extensive experience in evaluation of surgical quality process and outcome linkage has impacted national policy and changed guidelines. We performed a comprehensive evaluation of the Surgical Care Improvement Project (SCIP) implementation using national VA data. Defining robust metrics of surgical quality that are actionable and can lead to sustained improvement in our field are of utmost importance. I also have experience with risk prediction modeling for surgical patients. Our Decision Support for Safer Surgery study developed models of real-time risk prediction for major complications and prospectively validated our models in patients and with expert surgeons. We were able to discern where computational risk prediction has added value and where it falls short. We currently have a national study investigating readmissions following major surgical procedures to identify opportunities for improving care and reducing costs.

Melanie Hayden Gephart
Professor of Neurosurgery and, by courtesy, of Neurology and Neurological Sciences
BioI am a brain tumor neurosurgeon, treating patients with malignant and benign tumors, including gliomas, brain metastases, meningiomas, and schwannomas. I direct the Stanford Brain Tumor Center and the Stanford Brain Metastasis Consortium, collaborative unions of physicians and scientists looking to improve our understanding and treatment of brain tumors. My laboratory seeks greater understanding of the mechanisms driving tumorigenesis and disease progression in malignant brain tumors. We study how rare cancer cell populations survive and migrate in the brain, inadvertently supported by native brain cells. We develop novel cerebrospinal fluid-based biomarkers to track brain cancer treatment response, relapse, and neurotoxicity. Our bedside-to-bench-to-bedside research model builds on a foundation of generously donated patient samples, where we test mechanisms of brain cancer growth, develop novel pre-clinical models that reliably recapitulate the human disease, and facilitate clinical trials of new treatments for patients with brain cancer.

Britt Hedman
Professor of Photon Science
BioBritt Hedman’s research program is focused on the development and applications of x-ray absorption and emission spectroscopies using synchrotron radiation, with a scientific emphasis primarily on study of the electronic and structural aspects of metal ion active sites in bioinorganic and biological systems. A common theme is to investigate how structure at molecular and macromolecular levels relates to function.
A major long-term focus has been the active site of the enzyme nitrogenase, and the various nitrogenase metal clusters, including elucidating the electronic and geometric structure of those that are formed and changed along their biosynthetic pathways. Other systems of systematic studies include iron-sulfur cluster containing enzymes, blue and multi-copper proteins, heme-copper oxidases, and iron-containing oxidases. Methods developments include x-ray absorption spectroscopy (edge and extended fine structure - or EXAFS), including the application of multiple-scattering analysis in EXAFS studies of metal clusters relevant to bioinorganic systems, the development of methodology for polarized single crystal x-ray absorption spectroscopy, and methodology and instrumentation development for soft- through hard-energy XAS.

John P. Hegarty II
Clinical Assistant Professor, Psychiatry and Behavioral Sciences
BioI am a neuroscientist and Principal Investigator of the Stanford Clinical Neuroscience (CNS) Lab in the Department of Psychiatry and Behavioral Sciences as well as Director of Neuroimaging for the Autism and Developmental Disorders Research Program at Stanford. My innovative research studies clinical aspects of cognitive and behavioral neuroscience, with a special focus on examining the neural circuitry associated with important brain-behavior relationships that may underlie different psychological and psychiatric domains in autistic children, adolescents, and adults. The ultimate goal of this research is to improve our understanding of the development of different cognitive and behavioral skills in order to develop mechanistically driven interventions that will improve precision medicine for mental health. Biologically based diagnosis and treatment are extremely limited for most psychological and psychiatric conditions but also critically needed to increase early identification and improve treatment outcomes, especially for neurodevelopmental disorders in which early intervention is the most beneficial. My early career research has primarily focused on clinical neuroscience using neuroimaging (e.g., MRI & EEG) to examine the effects of different drugs and behavioral interventions on the brain, especially for developing biomarkers for improving treatment planning and monitoring biological changes in response to single dose and clinical trials.
My primary contributions to science thus far fall within these major categories: 1) identifying the neural correlates of individual differences in cognition and behavior, 2) developing new interventions and investigating the neurobiological substrates of response to treatment, 3) examining different factors that contribute to brain development, 4) summarizing and increasing accessibility to autism-related research, and 5) methods development for neuroimaging studies. My earliest research investigated the neurobiology of alexithymia, dyslexia, and stress using structural and functional magnetic resonance imaging to test theories of the mechanisms that contribute to differences in cognition and behavior. My subsequent dissertation research, in which I began to focus on neurodevelopmental disorders, examined the neural correlates of response to beta-blockers in autistic adults and also assessed the contribution of cerebellar circuits to the autism phenotype. During my postdoctoral training, I have developed further skills for working with children in multiple clinical research settings, especially for using advanced neuroimaging approaches to examine important brain-behavior relationships. This includes a recent K99/R00 from the National Institute of Child Health and Human Development (NCT04278898 & NCT05664789) that will assess the neurobiology of restricted and repetitive behaviors in autistic children and examine the efficacy and target engagement of a novel nutritional supplement and investigational drug, N-acetylcysteine (NAC), in the brain.

Martin Hellman
Professor of Electrical Engineering, Emeritus
BioMartin E. Hellman is Professor Emeritus of Electrical Engineering at Stanford University and is affiliated with the university's Center for International Security and Cooperation (CISAC). His most recent work, "Rethinking National Security," identifies a number of questionable assumptions that are largely taken as axiomatic truths. A key part of that work brings a risk informed framework to a potential failure of nuclear deterrence and then finds surprising ways to reduce the risk. His earlier work included co-inventing public key cryptography, the technology that underlies the secure portion of the Internet. His many honors include election to the National Academy of Engineering and receiving (jointly with his colleague Whit Diffie) the million dollar ACM Turing Award, the top prize in computer science. In 2016, he and his wife of fifty years published "A New Map for Relationships: Creating True Love at Home & Peace on the Planet," providing a “unified field theory” for peace by illuminating the connections between nuclear war, conventional war, interpersonal war, and war within our own psyches.
