    Clinical Assistant Professor, Medicine - Gastroenterology & Hepatology

    BioI am initially a Pittsburgh, PA native, but have been at Stanford University since 2012 for residency, fellowship, and now as faculty. It is exciting to be affiliated with one of the most dynamic and innovative medical institutions worldwide.

    My clinical and research interests focus on functional, motility, and esophageal disorders of the gastrointestinal tract. Outside of this sub-sub specialization, a significant portion of my practice is also devoted to the care of a broad range of “general gastroenterology” concerns.

    Functional, motility, esophageal, and general gastroenterology disorders are very common, and can cause significant disability. Some examples include irritable bowel syndrome, functional dyspepsia, gastroparesis, chronic nausea, chronic constipation, achalasia, and gastroesophageal reflux disease.

    Despite the common nature of these disorders, many are not well understood, leading to frustration among both patients and clinicians alike. Furthermore, there is an incorrect stigma associated with some of these disorders that “it is all in your head.” On the opposite side of the spectrum, there is sometimes an incorrect assumption that we will be able to pinpoint an exact underlying cause in all cases, but this is not possible with current technology. We aim to bridge this gap using the latest diagnostic testing and treatment paradigms, as well as a healing hand. Additionally, our group is actively engaged in multiple research projects and studies to drive the future of the field.

    Though I am early in my career, I am hoping that by the end the field will look nothing like it does today. I am hopeful, and I believe that we can revolutionize the field to better characterize gastrointestinal disorders, and come up with highly effective targeted treatments.

    Affiliate, Psych/Public Mental Health & Population Sciences

    BioLindsey Zimmerman, PhD, is a Clinical and Community Psychologist, and Implementation Scientist at the National Center for PTSD, Dissemination and Training Division of the Veterans Health Administration.

    Dr. Zimmerman is principal investigator of National Institutes of Health (NIH) and Veterans Health Administration (VA) research that enlists participatory system dynamics to increase timely patient access to evidence-based pharmacotherapy and evidence-based psychotherapy for depression, PTSD, alcohol and opioid use disorder.

    Participatory System Dynamics vs Audit and Feedback: A Cluster Randomized Trial of Mechanisms Of Implementation Change to Expand Reach of Evidence-Based Addiction and Mental Health Care (R01DA046651)

    The most common reasons Veterans seek VA addiction and mental health care is for help with opioid and alcohol misuse, depression and PTSD. Research evidence has established highly effective treatments that prevent relapse, overdose and suicide, but even with policy mandates, performance metrics, and electronic health records to fix the problem, these treatments may only reach 3-28% of patients. This study tests participatory business engineering methods to better meet the addiction and mental health needs of Veterans and the U.S. population.


    Participatory System Dynamics for Evidence-Based Addiction and Mental Healthcare (R21DA042198)

    Limited access and delays to high-quality, evidence-based mental health and addiction treatments can lead to patients getting too little or ineffective care and contribute to chronic patient impairment, relapse, and death by suicide or overdose. This study evaluates a system for resolving problems with patient flow and organization in health care systems, using electronic medical record systems and a high-level of input from healthcare leadership, frontline providers and patients.

    Participatory System Dynamics vs Usual Quality Improvement: Is Staff Use of Simulation an Effective, Scalable and Affordable Way to Improve Timely Veteran Access to High-quality Mental Health Care? (I01HX002521)

    Participatory system dynamics (PSD) helps improve quality with existing resources, critical in mental health and all VA health care. PSD uses learning simulations to improve staff decisions, showing how goals for quality can best be achieved given local resources and constraints. We aim to significantly increase the proportion of patients who start and complete evidence-based care, and determine the costs of using PSD for improvement.

    Temp - Non-Exempt, Rad/Veterans Affairs

    BioI am a visiting graduate student researcher under supervision of Dr. Dan Ennis at Radiological Sciences Laboratories and VA Palo Alto. My current research interests include cardiovascular flow imaging, in-vivo and in-vitro cardiac magnetic resonance imaging, patient-specific image-based modeling, quantitative image analysis, and application of novel 3D printing technology.

  • Andrew Zolopa

    Andrew Zolopa

    Professor of Medicine (Infectious Diseases) at the Stanford University Medical Center, Emeritus

    Current Research and Scholarly InterestsDr. Zolopa’s research applies a variety of clinical epidemiologic methods in an effort to optimize antiretroviral therapy and understand the impact of drug resistance on response to ARV. Areas of focus include the clinical application of resistance testing in optimizing antiretroviral therapy, clinical cohorts, trials of antiretroviral therapies and population-based epidemiologic evaluation of HIV resistance and efficacy of ARV therapy. More recently studies focused on premature aging in HIV.
