Dr. Chia-Hao Lee is a Schmidt AI in Science Postdoctoral Fellow at Cornell University, specializing in the fusion of atomic-resolution electron microscopy and artificial intelligence. His research harnesses deep learning and generative models like CycleGAN to analyze sub-picometer-scale distortions around atomic defects in electron microscopy images. Recently, he has focused on utilizing diffusion models to push the boundaries of electron ptychography, a state-of-the-art computational microscopy technique that reveals unprecedented 3D structural details of materials at atomic resolution.
