Nano-optics and light-matter interaction Lab
Welcome to our homepage! Our research group is affiliated with the Materials Research and Education Center in the Department of Mechanical Engineering at Auburn University. Our current research focuses on experimental nano-optics and light-matter interactions in emerging materials.
Recruitment: We are seeking motivated researchers and students at all levels to join the group. We are also interested in working with visiting students/scholars and high school students. Please feel free to contact
sdai@auburn.edu if you are interested.
