Recent Activities

Currently, I'm tackling the challenging task of analyzing the structure of nanoscale crystals using cryo-three-dimensional electron diffraction (cryo-3D ED), a method that overcomes the limitations of conventional techniques. While my career has long been focused on protein crystal structure analysis, I recently published a paper on the crystal structure of organic semiconductors. Even I'm surprised by this new direction!
