After completing his Ph.D., Breuer became a postdoctoral fellow in applied mathematics at Brown University with
Lawrence Sirovich. He later joined MIT as a faculty member in the Department of Aeronautics and Astronautics, where he worked for nine years before returning to Brown University in 1999. He is currently co-director of the Center for the Mechanics of Undersea Science and Engineering (MUSE). He was a visiting professor at the
University of Queensland in 2005,
Harvard University in 2008,
Paris Tech in 2015,
Imperial College and
Tel Aviv University in 2019 and the
University of Colorado in 2022. His research focuses on various topics in fluid mechanics, animal locomotion, and turbulent flows. His work examines bat and bird flight, fluid-structure interactions, vortex dynamics, renewable energy harvesting, bio-inspired engineering, and micro-scale bio-fluid mechanics. He holds patents related to Kinetic energy harvesting, Sensing and control of flows over membrane wings, Breuer was co-author of
Multimedia Fluid Mechanics (Camb. Univ. Press) and co-editor of
A Gallery of Fluid Motion (Camb. Univ. Press). == Awards and honors ==
