교원소개

The π-Lab explores photonic solutions for artificial intelligence with a focus on computer vision, a key technology driving autonomy, robotics, and intelligent systems. We are a multidisciplinary team with backgrounds in optics, computer science, and electrical engineering. By engineering hardware and software together, we co-optimize optics, electronics, and algorithms that enable faster, smarter, and more efficient visual intelligence.
