The NE2 lab is interested in linking structures with functions, especially in ways they haven’t connected before, and developing novel devices from the discoveries. Specifically, one of our current topics is to develop integrated topological phononic systems for applications like miniaturized wireless communication and quantum information. To achieve such goals, we apply electrical engineering, nanotechnology, physics, and materials engineering methods.

Our enthusiasm for research is driven by curiosity, the fun of exploration, and the need to improve our world. We also like to connect research with society through reach-out events.
