DESCRIPTION: In recent years\, ground-based high-resolution spectroscopy h
 as become an invaluable tool to characterise the atmospheres of exoplanets
 . It has the ability of resolving molecular bands into the individual line
 s\, and of directly detecting the changing radial velocity of close-in pla
 nets through cross-correlation with template spectra. High resolution spec
 troscopy delivers robust detections of atomic and molecular species in tra
 nsmission and dayside spectra of transiting and non-transiting hot Jupiter
 s. In addition\, it allows us to measure planet rotation and winds. With t
 he E-ELT\, this technique will be potentially applicable to temperate plan
 ets orbiting M-dwarfs to look for biomarkers. I will review the state of t
 he art of the method and explain how the community is working to achieve a
  number of key improvements - both observational and in the modelling - cr
 ucial to enable frontier exoplanet science in the next decade. These inclu
 de the joint analysis of high-resolution and low-resolution spectra\, and 
 the combination of high contrast imaging and high-resolution spectroscopy.
