She is currently a neonatology fellow at the Children’s Hospital of Philadelphia. Her research has focused on how genetics affects clinical care, from the perspective of doctors and patients. Her most recent work explored ways to enhance physician’s understanding of disability and how learning about a patient's life beyond a genetic diagnosis can enhance medical care. Katharine combined her Neonatology and ELSI fellowships and investigated the ethical and social dynamics of genetic testing in the neonatal intensive care unit.

LaKisha David, PhD

Assistant Professor, Anthropology, University of Illinois Urbana-Champaign

LaKisha David successfully defended her PhD in Human Development and Family Studies at the University of Illinois at Urbana-Champaign. She studies human development and family aspects of genetic genealogy. Her research examines processes of family identity development and ethnic identity development among African American adults who use direct-to-consumer genetic genealogy testing services to engage in social interactions with genetic relatives from Africa. Her research also examines the perceptions of Ghanaians interacting with African Americans identified as the genetic descendants of their ancestors who were taken away during the Transatlantic Slave Trade. From 2013 to 2016, she was a National Science Foundation Graduate Research Fellow at the Massachusetts Institute of Technology and the University of Illinois at Urbana-Champaign focusing on international development in Ghana. As an ELSI post-doctoral fellow at Penn, she plans to explore ethical, legal, social, and technical implications of genetic relatedness among Ghanaian and African American families separated during the Transatlantic Slave Trade.

Isabel Gabel, PhD

Instructor, Stevanovich Institute on the Formation of Knowledge, The University of Chicago

Isabel Gabel is a historian of science, medicine, and political thought. Her work explores how the modern life sciences created spaces of uncertainty and irresolvability which in turn reshaped the epistemological foundations of liberalism in the twentieth century. At SIFK she is working on a history of complexity, tentatively entitled At the Edges of Chaos: Complexity Theory between Science and Governance. Bringing together histories of molecular biology, cybernetics, and big data, the project explores the rise of complexity science in Europe and the United States after 1970. It charts complexity’s transformation from a mathematical approach to chaos and nonlinearity, to a set of new methods for theorizing and managing the neoliberal state in fields such as urban studies and finance. Isabel is also in the process of completing her first book, Experiments in History: French Biology and the Fate of Liberal Universalism, about the role of biology in the emergence of poststructuralism and liberal historicism after the Second World War. Isabel’s publications have appeared in journals including History of the Human Sciences and Revue d’histoire des sciences. She received her PhD from Columbia University and was most recently an ELSI Postdoctoral Fellow at the University of Pennsylvania’s Perelman School of Medicine.

Isabel received her PhD in history at Columbia University and from 2011-2012 was a Predoctoral Research Fellow at the Max Planck Institute for the History of Science in Berlin. To learn more about Isabel Gabel’s work and to see her publications, visit

Madison K. Kilbride, PhD

Assistant Professor, Department of Philosophy, University of Utah

Madison Kilbride, PhD, is an Assistant Professor in the Department of Philosophy at the University of Utah. Dr. Kilbride’s scholarship addresses the ethical, legal, and social implications (ELSI) of genetics and genomics, with a focus on direct-to-consumer (DTC) genetic testing. Her current research is supported by a K01 Career Development Award from the National Human Genome Research Institute (NHGRI). Her K01 project, ”Evaluating the Risks and Benefits of the Next Generation of Direct-to-Consumer Genetic Tests,” aims to develop a new approach to studying DTC outcomes that does not rely on partnering with a DTC company and can be used to study a wide range of DTC tests and companies. In studying the feasibility of her approach, Dr. Kilbride will begin to address the lack of real-world data for individuals undergoing DTC genetic testing for high-risk cancer and cardiac disease susceptibility genes. In addition to her work in ELSI, Dr. Kilbride is also interested in the physician-patient relationship and gatekeeping in medicine.

Dr. Kilbride was previously an Instructor in the Department of Medical Ethics and Health Policy at Penn (2020-2021).  She was also a T32 Fellow in the Penn Postdoctoral Training Program in the Ethical, Legal, and Social Implications (ELSI) of Genetics and Genomics (2017-2020).
