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. Her 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 she serves as the quality lead for the section of Palliative Medicine. She is also a Core Investigator at the Center for Innovation to Implementation (Ci2i) in the VA Palo Alto Health Care System and serves as PI or co-investigator on multiple ongoing studies representing over 25 million dollars of competitive government grant funding. She is 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 she leads 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.
Dr Giannitrapani has 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. She has 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.

Currently, she is co-leading a Lancet Series on Global Health and Foreign Engagement with Professor Gary Darmstadt. Recently, she published significant findings on the impact of foreign aid sanctions on maternal and child health in The Lancet Global Health, garnering attention in Nature Medicine, The Stanford Report, and numerous international media outlets due to its critical relevance in today’s geopolitical landscape.
Dr. Gibson collaborates with the United Nations High Commission for Human Rights to develop a universal monitoring system to assess the impact of sanctions on human rights. Her research has been cited in UN General Assembly meetings by the Special Rapporteur on Unilateral Coercive Measures. She also contributes to mental health reports for the International Criminal Court's prosecution of war crimes and collaborates with the Global Burden of Disease Consortium at the Institute of Health Metrics and Evaluation, University of Washington, to publish health estimations and forecasts in The Lancet.
Leading a diverse team of academic scholars and independent experts and consultants, Dr. Gibson fosters a collaborative environment that encourages participation across various fields, including politics, statistics, simulation modeling, and social media design. Together, they aim to tackle complex questions regarding how civilian and child well-being is impacted by geopolitical challenges and foreign policy decisions. Dr. Gibson welcomes inquiries from those interested in conducting interdisciplinary research with real-world impact. She is responsive to journalists and media outlets seeking to understand issues which fall at the intersection of geopolitics, foreign policy, and health.

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.

Joshua Gillard
Postdoctoral Scholar, Cardiovascular Medicine
BioDr. Josh Gillard is a Canadian biomedical data scientist with experience in bioinformatics, machine learning, and immunology. After completing a BSc and a MSc in Experimental Medicine at McGill university, he relocated to the Netherlands for his PhD in bioinformatics at Radboud University in Nijmegen. During his PhD, he gained experience analyzing and interpreting complex immunological data (bulk and single-cell transcriptomics, high-dimensional cytometry, high-throughput proteomics) derived from human observational or intervention studies (vaccination and experimental human infection). This work revealed molecular and cellular correlates of clinically important endpoints such as disease severity, symptom progression, and antibody responses. In 2022, Josh relocated to Stanford to join the Gaudilliere lab to develop and apply multi-omic data integration and machine learning techniques, establishing that early gestational immune dysregulation can predict preterm birth. Since 2024, in the Ashley lab, Josh is developing deep learning models to investigate aberrant splicing in cardiovascular disease.

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.
