Dipen Sinha of Los Alamos National Laboratory’s Materials Synthesis and Integrated Devices group studies acoustics and its applications, including how it is possible to use sound to solve problems in health, national security and for industry. “I take advantage of the nature of sound waves and often manipulate these waves to solve technically challenging problems related to energy and national security,” Sinha said. “How an object vibrates also tells a lot about it. Sound can exert force on objects. By carefully manipulating acoustic forces it is possible to create novel structures and even unique materials that are otherwise not possible with conventional fabrication processes.”
