BioDr. Ghiam is an American and Canadian Board-Certified Radiation Oncologist with the Stanford Medicine Cancer Center and a Clinical Associate Professor in the Department of Radiation Oncology at Stanford University School of Medicine. After completing an MSc in Molecular Biology & Genetics at the University of Montreal, he completed a residency in Radiation Oncology and fellowship in Head & Neck and GU radiation oncology at the University of Toronto.
He diagnoses and treats various conditions specializing in head & neck cancer, genitourinary malignancies, and metastatic disease. His treatment expertise includes oligometastatic disease, palliative radiation therapy, stereotactic ablative radiotherapy, and proton therapy.
Dr. Ghiam has contributed to the field through his authorship of technology- and biology-based publications and collaboration in clinical trials. He has been recognized by awards from the American Society for Radiation Oncology (ASTRO), the Canadian Association of Radiation Oncology (CARO), and the Universities of Toronto and Pennsylvania. In recognition of his educational work, he received two prestigious teaching awards for teaching residents and medical students. He has presented his research work nationally and internationally and authored and co-authored several papers.
Dr. Ghiam's interest lies in exploring novel AI-powered technologies that can enhance patient outcomes, and bridge health equity gaps in radiation oncology. He is also interested in clinical trials of innovative radiation therapy techniques with a focus on leveraging technology and biology to reduce toxicity and increase precision.
Dr. Ghiam is dedicated to academia, education, and diversity. He is committed to improving patient outcomes and changing the role of supportive care in radiation oncology by promoting quality standards and utilizing palliative radiotherapy to enhance the quality of life for his patients.
Dr. Ghiam practices evidence-based care with compassion and treats his patients as he would his own family. -
Amato J. Giaccia
Jack, Lulu and Sam Willson Professor, Professor of Radiation Oncology, Emeritus
Current Research and Scholarly InterestsDuring the last five years, we have identified several small molecules that kill VHL deficient renal cancer cells through a synthetic lethal screening approach. Another major interest of my laboratory is in identifying hypoxia-induced genes involved in invasion and metastases. We are also investigating how hypoxia regulates gene expression epigenetically.

Karleen Giannitrapani
Assistant Professor of Medicine (Primary Care and Population Health)
BioIn contrast to bounded teams with static membership, dynamic teaming reflects the common challenge of interdisciplinary healthcare teams with changing rosters. Such dynamic collaboration is critical to addressing multi-faceted problems and individualizing care. At present, off the shelf interventions to improve the way healthcare teams work - often assume static and bounded teams. Dr Giannitrapani intends to leverage design approaches to build a new kind of healthcare “teaming intervention,” which respects the nature of their constantly changing membership and more closely aligns with how healthcare teams actually collaborate. Their expertise includes organizational behavior, building interdisciplinary teams, implementation science, mixed methods-research, quality improvement, pain and palliative care research, and global health.
In addition to the Assistant Professor role in Division of Primary Care and Population Health at Stanford University School of Medicine they serve as the quality lead for the section of Palliative Medicine. They are also a Core Investigator at the Center for Innovation to Implementation (Ci2i) in the VA Palo Alto Health Care System and serve as PI or co-investigator on multiple ongoing studies representing over 25 million dollars of competitive government grant funding. They are also a Director of the VA Quality Improvement Resource Center (QuIRC) for Palliative Care, supporting Geriatrics and Extended Care programs for 170 Veterans Affairs facilities nationally. In QuIRC they lead a portfolio of projects on improving the processes that interdisciplinary teams can leverage to improve pain and symptom management among high-risk patients; a specific focus of their work is to bridge the gap of poor palliative care integration in the perioperative period.
They have given hundreds of presentations and have over 70 peer reviewed publications in high quality medical and health services delivery journals such as Medical Care, JAMA Surgery, the Journal of General Internal Medicine, the Journal of Pain and Symptom Management and Pain Medicine. They received a 5-year VA Career Development Award on building better teams across disciplines and was an American Academy of Hospice and Palliative Medicine Research Scholar for related work. -
William Giardino
Assistant Professor (Research) of Psychiatry and Behavioral Sciences (Sleep Medicine)
Current Research and Scholarly InterestsWe aim to decipher the neural mechanisms underlying psychiatric conditions of stress, addiction, and sleep/circadian dysregulation. Our work uses combinatorial technologies for precisely mapping, monitoring, and manipulating neural circuits that regulate emotional states. We are especially focused on the behavioral functions of neuropeptide molecules acting throughout the circuitry of the extended amygdala- particularly in a brain region called the bed nucleus of the stria terminalis (BNST).

Erin Gibson
Assistant Professor of Psychiatry and Behavioral Sciences (Sleep Medicine)
Current Research and Scholarly InterestsGlia make up more than half of the cells in the human brain, but we are just beginning to understand the complex and multifactorial role glia play in health and disease. Glia are decidedly dynamic in form and function. Understanding the mechanisms underlying this dynamic nature of glia is imperative to developing novel therapeutic strategies for diseases of the nervous system that involve aberrant gliogenesis, especially related to changes in myelination.

Professor of Anesthesiology, Perioperative and Pain Medicine, Emerita
Current Research and Scholarly InterestsAstrocytes, microglia and neurons interact, and have unique vulnerabilities to injury based on their patterns of gene expression and their functional roles. We focus on the cellular and molecular basis of brain cell injury in stroke. We study the effects of altering miRNA expression, altering levels of heat shock and cell death regulatory proteins. Our goal is to improve outcome by improving mitochondrial function and brain cell survival, and reducing oxidative stress and inflammation.

Lisa Giocomo
Professor of Neurobiology
Current Research and Scholarly InterestsMy laboratory studies the cellular and molecular mechanisms underlying the organization of cortical circuits important for spatial navigation and memory. We are particularly focused on medial entorhinal cortex, where many neurons fire in spatially specific patterns and thus offer a measurable output for molecular manipulations. We combine electrophysiology, genetic approaches and behavioral paradigms to unravel the mechanisms and behavioral relevance of non-sensory cortical organization. Our first line of research is focused on determining the cellular and molecular components crucial to the neural representation of external space by functionally defined cell types in entorhinal cortex (grid, border and head direction cells). We plan to use specific targeting of ion channels, combined with in vivo tetrode recordings, to determine how channel dynamics influence the neural representation of space in the behaving animal. A second, parallel line of research, utilizes a combination of in vivo and in vitro methods to further parse out ionic expression patterns in entorhinal cortices and determine how gradients in ion channels develop. Ultimately, our work aims to understand the ontogenesis and relevance of medial entorhinal cortical topography in spatial memory and navigation.
