    Associate Professor of Medical Sciences (in Medicine and in Medical Humanities and Ethics)

    Maya Sabatello, LLB, PhD is an Associate Professor of Medical Sciences (in Medicine) at the Center for Precision Medicine and Genomics, Department of Medicine; Associate Professor (in Medical Humanities and Ethics), at the Division of Ethics, Department of Ethics and the Humanities; and Co-Director of the Precision Medicine: Ethics, Politics, and Culture Project at Columbia University. She is a former litigator with trans-disciplinary background and has extensive experience in national and international policy-making relating to human and disability rights. Sabatello studies how biomedical technologies and genomic information impact social structures, marginalized communities, and individual rights and health outcomes. Her scholarship focuses on law, society, medicine, and disability; regulations of reproductive technologies; and the ethical, legal, and social implications of genetics and precision medicine. Her projects include Disability, Diversity and Trust in Precision Medicine Research (R01 HG010868), Evidence-based Policy Recommendations to Address Bioethical Challenges in the Return of Genetic Results in Nephrology (U01 DK100876-07 Supp); the psychosocial impact of genomic data on adolescents and family relations (studies funded by the Children Cardiomyopathy Foundation and Columbia University’s Precision Medicine and Society); and Disability Inclusion in Precision Medicine Research (P50 HG007257-05S1). She recently completed a K01 Award that explored the uses of psychiatric genetics evidence in civil litigation and non-clinical settings, such as child custody disputes and schools (K01 HG008653).

    Dr. Sabatello has been a Gray Matters Fellow, a Research Fellow in Medical Ethics at Harvard Medical School, and a Visiting Research Fellow at Columbia University’s School of Law.

  • Alexis Walker, PhD

    Assistant Professor

    Alexis Walker, PhD is an interdisciplinary scholar trained in Science and Technology Studies (STS), political anthropology, organizational studies, and bioethics. Her research investigates the social dynamics of financial and private sector organizations in health and medicine. She is currently Principal Investigator on a four-year project (2019-2023) examining perspectives from members of the commercial genomics industry on the social and ethical dynamics of their field. This work is funded by an Early Career Investigator award (K99/R00) from the National Human Genome Research Institute. 

    Dr. Walker’s previous research has examined the organizational dynamics of international financial institutions making loans for global health projects, the ethics of “precision rationing,” and the politics of patenting biotechnology. Her work employs qualitative methods, including ethnography, in-depth interviews, and document analysis. Her most recent work includes additional survey methods and town hall-style focus groups. 

    Prior to coming to Columbia, Dr. Walker was a postdoctoral fellow at the Berman Institute of Bioethics at Johns Hopkins University. Dr. Walker received her doctorate from Cornell University’s Department of Science and Technology Studies, a master’s degree in political sociology and STS from University of Strasbourg (France), and an undergraduate degree in Biology from Brown University.

  • Emily Vasquez

    Project Director

    Emily Vasquez, MPhil, MPH, ABD, is an ethnographer of science, medicine, and public health. Drawing on the sociology of health and medicine, science and technology studies (STS), and critical race studies, her research examines relationships between knowledge, technology, health, identity, and social justice. She studies these issues in the context of global health policy and initiatives, especially global and national-level responses to epidemics of chronic disease. Her research has been supported by fellowships from, among others, the National Science Foundation (Science, Technology, and Society Program) and the ACLS/Mellon Foundation. She is a doctoral candidate completing a PhD in sociology and public health in the Department of Sociomedical Sciences at Columbia University.

  • Jessica Martucci

    Research Associate

    Jessica Martucci, PhD, MBE is a historian of science, medicine, and technology. Her first book, Back to the Breast: Natural Motherhood and Breastfeeding in America  (University of Chicago Press, 2015), examines the story behind the return of breastfeeding in the U.S. at the end of the 20th century. More generally, her research examines how people from historically marginalized or “outsider” communities interpret, create, contest, influence, and engage with expert scientific and medical knowledge. She is a member of the International Consortium on Catholicism and Medicine at KU Leuven in Belgium, where she examines the role of the U.S. Catholic Church in shaping mainstream policies and practices in healthcare. Between 2016 and 2020 she ran the Science & Disability Project, an oral history-based research program geared towards developing new historical insights and policy recommendations informed by the first-hand experiences of disabled people in STEM(edicine). As an outgrowth of that work, she co-founded the Beyond Better Project, an interdisciplinary, multi-media public medical humanities effort that seeks to destabilize ableist narratives in American healthcare through oral history, storytelling, and art. Her work has appeared in popular and academic outlets including: NursingCLIO.org, Distillations, All Of Us, the AMA Journal of Ethics, the  Journal of Women’s History, the Journal of Medical Ethics, the International Journal of Feminist Approaches to Bioethics, and the Bulletin in the History of Medicine, among others. Jessica received her PhD in the History & Sociology of Science and a Master’s of Bioethics from the University of Pennsylvania and her undergraduate degree in Biology and Environmental Studies from Oberlin College.

  • Mike Bentz, MPH

    Research Coordinator

    Mike Bentz, MPH, worked for several years on an NIH-funded clinical trial investigating race-specific clinical therapies. This is one of the reasons for which he became interested in the justifications for such therapies and how these justifications intersect with emergent genetics technologies.
