  We present the results of two 2.3 micron near-infrared radial velocity
surveys to detect exoplanets around 36 nearby and young M dwarfs. We use the
CSHELL spectrograph (R ~46,000) at the NASA InfraRed Telescope Facility,
combined with an isotopic methane absorption gas cell for common optical path
relative wavelength calibration. We have developed a sophisticated RV forward
modeling code that accounts for fringing and other instrumental artifacts
present in the spectra. With a spectral grasp of only 5 nm, we are able to
reach long-term radial velocity dispersions of ~20-30 m/s on our survey
targets.
