Biography: Dr. Aubry is the Raymond J. Lane Distinguished Professor and Head of the Department of Mechanical Engineering at Carnegie Mellon University. Her awards include the Presidential Young Investigator Award from the National Science Foundation (NSF), the Ralph R. Teetor Educational Award from the Society of Automotive Engineers (SAE), and her election as Fellow of the American Physical Society (APS), Fellow of the American Society of Mechanical Engineers (ASME), Fellow of the American Association for the Advancement of Science (AAAS), and Senior Member of the American Institute of Aeronautics and Astronautics (AIAA). She has served as Past Chair (currently), Chair, Vice Chair and Member-at-Large of the U.S. National Committee for Theoretical and Applied Mechanics (USNC/TAM) under the auspices of the National Academies. She is also a member of the Congress Committee of the International Union for Theoretical and Applied Mechanics (IUTAM) and was appointed Chair of the National Academy of Sciences (NAS) delegation to the IUTAM General Assembly (2008-2009). Dr. Aubry has been serving on many APS and ASME committees, numerous NSF and National Research Council review panels, and a certain number of international boards and review panels at foreign institutions (particularly in Europe and Asia). She currently serves as Associate Editor of ASME Journal of Applied Mechanics and is a member of the Editorial Board of Mechanics Research Communications (Elsevier). She has given numerous invited seminars on her research at various universities and conferences. Recent lectures include a keynote lecture at the SIAM Conference on Applications of Dynamical Systems (2003), a conference invited lecture at the Annual Meeting of the Division of Fluid Dynamics (American Physical Society) (2006), the Grace Hopper Lecture at the University of Pennsylvania (2007), the Haythornthwaite Foundations’ Distinguished Lecture at Temple University (2008), and the Lindseth Lecture at Cornell University (2008).

Research Interests: Professor Aubry’s research is in the area of fluid dynamics. She pioneered the modeling of open flow turbulence and other complex flows and systems using advanced decomposition techniques and dynamical systems theory. Her current group’s research focuses on microscale flows or microfluidics, including micromixers, droplet generators, and manipulators of particles suspended in liquids. Particularly, her team has proposed new techniques for effective mixing, droplet generation, and assembly of micro- and nano-sized neutral particles at fluid-fluid interfaces into two-dimensional arrays (monolayers). While many others use passive methods such as altered geometries to achieve some of these goals, the group uses mostly active techniques, particularly external electric fields. The tools used to study such systems are theoretical, numerical and experimental, taking into account the strongly coupled multiphysics involved particularly at the interface between fluid dynamics and electrostatics.
