We work to:

  • Identify mechanisms underlying health inequities, including social determinants of health and public policies
  • Develop and evaluate community-engaged interventions to reduce health disparities
  • Nurture cross-disciplinary collaborations among researchers, clinicians, and community stakeholders to produce high-impact, action-oriented, policy-relevant research

Health disparities adversely affect groups of people who have systematically experienced greater obstacles to health, based on their racial or ethnic group, socioeconomic status, immigration status, sexual orientation, geographic location, or other characteristics historically linked to racism or exclusion. A primary focus of this lab is the immigrant and refugee communities, but our work addresses the needs of diverse communities who do not benefit from health care advances equally.

  • The Intersection of Neurology and Police Violence
    Dr. Saadi was the senior author on a JAMA Neurology Viewpoint on Police Use of Neck Restraints, which received wide media coverage. Read Dr. Saadi’s interview with WGBH All Things Considered. This Viewpoint paved the path to an American Academy of Neurology position statement against the use of neck restraints by law enforcement. Dr. Saadi and colleagues have also written a Washington Post Op-Ed about the bogus diagnosis of “Excited Delirium” to justify deaths occuring in police custody.

  • 2020 STAT Wunderkind

  • The Health Consequences of Immigration Detention
    Substandard medical care and poor conditions in immigration prisons can be a catalyst for worsening health. Dr. Saadi has served as a medical expert assessing immigration prison conditions of confinement and published about these conditions both in academic journals and the lay press, such as this Op-Ed in the Los Angeles Times. She has also spoken with various news agencies regarding immigration prison conditions and related health consequences, including The Atlantic and The Huffington Post.
  • Immigrant-friendly Health Systems
    Dr. Saadi has advanced the concept of “immigration-informed” care, which includes institutional policies and actions aimed at mitigating immigration-related concerns among patients and healthcare staff. Having first coined “Sanctuary Hospitals,” Dr. Saadi has detailed the implementation of “Immigrant friendly” institutional policies in academic publications (read more here and here) as well as a publicly-available toolkit and videos available at www.DoctorsForImmigrants.com.
