Keith Brown is an Assistant Professor of Mechanical Engineering at Boston University, interested in transport processes at the nanoscale. Particularly, he is interested in how the nanostructure of materials affects the way light, heat, electrons, and molecules can move through a system. He focuses on answering fundamental questions in these areas and exploring new materials systems that offer novel ways of tailoring these processes. Often, the ability to answer unique questions stems from realizing new capabilities for making and imaging materials, so a major thrust of his research is the development of enabling techniques, especially those related to scanning probe microscopy.
