Kristina Elizabeth Hawk
Clinical Assistant Professor, Radiology - Rad/Nuclear Medicine
BioKristina Elizabeth Hawk, MS MD PhD is a Nuclear Medicine Physician and Neuroradiologist. As a physician scientist, integrated MD/PhD training helped build a foundation to explore translational research efforts, using a full and intricate understanding of the research process, and the developed ability to understand, discuss and teach new emerging concepts. Dr. Hawk’s dissertation in Neuroscience focused on the regulation of Nitric Oxide Synthase in the dorsal and ventral striatum, exploring the neurochemical role of nitric oxide producing interneurons, and their ability to coordinate dopaminergic and glutamatergic signaling in areas of the brain relevant to cognition and motivated behavior.
Eager to expand her passion into the field of Medical Radiation Physics, she also completed a separate Masters degree in Medical Radiation Physics. This provided her with in depth training of how therapeutic and diagnostic instruments use both ionizing and non-ionizing radiation in the clinical setting. She then completed her Medical Doctorate and Diagnostic Radiology Residency at the University of Southern California (USC), learning the art of medicine while serving the diverse population at Los Angeles County Hospital.
Dr. Hawk completed clinical fellowship requirements in Nuclear Medicine at USC, and is now Board Certified by the American Board of Nuclear Medicine. She also completed a Neuroradiology fellowship at USC, and is Board Certified the American Board of Radiology. She served as both the Chief Resident and Chief Neuroradiology Fellow.
Dr. Hawk has held multiple local and national leadership positions, including positions in the American College of Radiology (ACR), the American College of Nuclear Medicine (ACNM) and the Society of Nuclear and Molecular Medicine (SNMMI). Dr. Hawk is an editorial board member of the Journal of the American College of Radiology (JACR). She has served as the Vice-Chair for Education for the Nuclear Medicine Resident Organization of the ACNM, and the Educational Liaison for the Resident and Fellow Section of the ACR. Currently, she serves on the national ACR Commission for Women and General Diversity as well as the ACR Commission on Nuclear Medicine. Dr. Hawk also sits on the ACR Council Steering Committee.
Dr. Hawk is committed to continually exploring the beautiful applications of ionizing and non-ionizing radiation to image and treat the human body. -
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.

Rose Heald
Masters Student in Translational Research and Applied Medicine, admitted Autumn 2025
BioAs a Master’s student in Translational Research and Applied Medicine at Stanford Medicine, I’m passionate about bridging the gap between scientific discovery and real-world clinical impact. My career interests lie at the intersection of science and business, with a focus on advancing the development and implementation of novel therapeutics—particularly in the areas of genetics, rare disease, and neurodegenerative diseases.
I bring experience in clinical research, including work on the BabySeq Project, a pioneering study of genomic newborn screening (gNBS). This experience sparked my ongoing interest in how genomic technologies can be implemented to identify actionable health risks early in life. I continue to contribute to this field through my involvement with the International Consortium on Newborn Sequencing (ICoNS), a global initiative advancing gNBS research. -
