In this talk, I will review the current landscape of ground-based exoplanet imaging efforts, including the latest discovery and results of our on-going survey for planets in systems with debris disks. In this context, I will present the status of wavefront control experiments with the Palomar Stellar Double Coronagraph, and the upgrade of Keck-NIRC2 with an L-band vortex coronagraph. I will describe the scientific niches enabled by this new high contrast imaging mode, and detail our plans for a deep survey of young M-dwarfs looking for giant planets close to the ice lines. Finally, I will discuss additional upgrade options for Palomar and Keck that will open new observational windows in exoplanet science, namely polarimetry and high resolution spectroscopy. High contrast high resolution spectroscopy on large telescopes such as Keck, or even better TMT, will indeed allow us to apply Doppler mapping techniques to exoplanets, a very exciting prospect.
