I am a Lecturer and PhD candidate in the Department of the History of Science at Harvard University. My dissertation, Diagnosing Uncertainty: Cystic Fibrosis, Disease Definitions, and Diagnostic Challenges in Medicine, examines why diagnostic uncertainty persists in medicine and the impact of such uncertainty on patients and families. Before embarking on a career as a historian, I was initially trained as a biologist, receiving an AB in Molecular Biology from Princeton University and a PhD in Virology from the Division of Medical Sciences at Harvard University. After post-doctoral research at Harvard, I spent over a decade teaching undergraduate students in the classroom and in the laboratory, including six years on the faculty in the Department of Biological Sciences at Wellesley College.
