Daniel Fletcher is the Purnendu Chatterjee Chair in Engineering Biological Systems and a professor of Bioengineering. He joined the bioengineering faculty in 2002 and advanced from Associate Professor to Professor in mid 2010. He is also currently serving as Vice Chair for Bioengineering. His research interests include optical and force microscopy, microfabrication, mechanical properties of cells. The Fletcher Lab combines bioengineering, biophysics, and molecular biology to understand how cells move, communicate, and become diseased. The lab asks fundamental questions about how cells are assembled from their molecular components, as well as applied questions about how those components can be detected or modified to fight disease. This work often involves developing new experimental methods, microscopy techniques, and microfabricated tools. The group also uses theory and computation to guide experimental design and interpret data. Its research in mechanobiology, immunoengineering, and disease diagnostics is ultimately aimed at understanding how biological systems function at a mechanistic level in order to develop new strategies to improve health.
