I will present the last results of the Transit Monitoring in the South (TraMoS) project. Since 2008, TraMoS has monitored transits of 30 exoplanets with telescopes located in Chile with the following goals: (1) to refine the physical and/or orbital parameters of those exoplanet systems, and (2) to search for Transit Timing Variations (TTVs) and perturbations in other transit parameters, that could indicate the presence of additional bodies in the system.   I will also discuss recent results and the scope of ongoing/future exoplanets projects at the IAC, in particular: transmission spectroscopy of selected exoplanets, secondary eclipse observations and dynamical simulations to validate/confirm exoplanets candidates.
