Speech title: World’s Deepest-Penetration and Fastest Cameras: Photoacoustic Tomography and Compressed Ultrafast Photography
Abstract: We developed photoacoustic tomography to peer deep into biological tissue. Photoacoustic tomography (PAT) provides in vivo omniscale functional, metabolic, molecular, and histologic imaging across the scales of organelles through organisms. We also developed compressed ultrafast photography (CUP) to record 10 trillion frames per second, 10 orders of magnitude faster than commercially available camera technologies. CUP can tape the fastest phenomenon in the universe, namely, light propagation, and can be slowed down for slower phenomena such as combustion.

C. Eringen Medal from Society of Engineering Science in 2017.
Speech title: Photonics beyond Diffraction Limit
Abstract: Compared with electronics that is already at nanoscale today, photonic circuits remain rather bulky due to optical diffraction limit. I will discuss physics in scaling down of photonics that is important for both optical sciences and modern information technology. We proposed a new optical cavity design using indefinite medium that exhibits an anomalous scaling law than conventional cavities which was confirmed experimentally. I will further present nanoscale waveguide and laser circuits using hybrid plasmons that can be multiplexed into a single waveguide‐an effort towards integrated photonics at nano‐scale. Finally, I will discuss non‐Hermitian optics that is capable to sort color simultaneously at nano‐scale for potential ultrahigh resolution imager.
