Harnessing Sound for Health: A Conversation with Tim Colonius

06-18-21

When a person develops a kidney stone or a gall stone—hard accumulations of minerals and other compounds created by the body—they can experience a great deal of pain and discomfort. Lithotripsy is the practice of breaking gall or kidney stones into small pieces within the body using shockwaves produced by a machine called a lithotripter. A new form of lithotripsy has been under development with the help of Tim Colonius, Frank and Ora Lee Marble Professor of Mechanical Engineering. [Caltech story]

Desbrun Elected to ACM SIGGRAPH Academy

Simon Toedtli Receives 2021 Richard B. Chapman Memorial Award

06-17-21

Simon Toedtli, a graduate student working with Professor Beverley McKeon, is the recipient of the 2021 Richard B. Chapman Memorial Award. His doctoral research combined direct numerical simulations and modal analyses to investigate the physics of closed-loop wall transpiration in a turbulent channel flow and to build low-order flow models for controller design. Both aspects contribute towards the development of drag-reducing control schemes for engineering applications, and will help make future transportation vessels more sustainable. Simon is continuing his studies in fluid mechanics as a postdoctoral fellow at Johns Hopkins University, where he will work on data assimilation for turbulent flows. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.
