Key Words: Physics, ultrasound, biomedical

Research Description: Our lab does research involving ultrasonic waves. These are sonic waves at frequencies beyond the range of human hearing. We use ultrasound to determine the physical properties of meta-materials which are substances that are constructed using microscopic particles. We also study biomaterials including mammalian tissues, tissue mimicking materials, biopolymers and plant matter. Our other main thrust involves the physical effects of ultrasound. At high powers, ultrasonic waves can be used to burn remote lesions in tissues, create a streaming current in a fluid, levitate objects and cavitate liquids.
