    Mohsen Malekinejad MD, MPH, Dr.PH is an Assistant Professor in the Department of Epidemiology and Biostatistics, the Philip R. Lee Institute for Health Policy Studies (IHPS), and the Institute for Global Health Sciences (IGHS), and the director of the Global Reduce Adverse Childhood Experiences (GRACE) Initiative at UCSF.

    Dr. Malekinejad is medical epidemiologist with expertise in systematic review and meta-analysis, sampling methods for hard-to-reach populations and disease surveillance, with substantive foci in HIV/AIDS, substance use, and most recently childhood adversities. He has also published on TB, sexually transmitted diseases, hepatitis, and other areas of public health addressing health disparities among underserved populations such as persons who inject drugs, non-US-born populations, men who have sex with men, and incarcerated populations. He has worked extensively as part of economic modeling teams.

    Dr. Malekinejad is experienced in leading large research teams domestically and internationally. He has been the PI of several smaller projects and project director of several large multi-site NIH or CDC-funded projects Over the past seven years, he has collaborated with other UCSF investigators as co-investigator and project director on a variety of grants, all expanding his technical expertise and leadership skills (1) Consortium to Assess Prevention Economics (CAPE) (CDC: 2014-2019) in which he led over 15 systematic review projects, (2) Global Health Decisions (GHD) (NIH-funded: 2010 – 2013). In GHD, Dr. Malekinejad led a team that developed a HIV disease burden reduction and cost-effectiveness model for combinations of prevention and treatment strategies via a graphically user-friendly web interface. (3) Global Health Intervention Review (GHIR) (Kaiser Family Foundation-funded: 2009 – 2010). In GHIR Dr. Malekinejad conducted syntheses of systematic reviews on the evidence of efficacy of interventions for eight globally important diseases including HIV/AIDS, TB, and Malaria, incorporating strength of evidence assessments into final review products.

    Dr. Malekinejad has also led multiple collaborative international projects studying the intersection of substance use and blood-borne infections, including an NIH-funded project to study risk factors of transitioning to injection among opioid users. He served as the President of the Scientific Association for Public health in Iran (SAPHIR, 2017-2019), and currently is the co-chair of the Diversity, Equality, and Inclusion at the IGHS. Dr. Malekinejad teaches a systematic review course at UCSF.
