Susana Barros is a researcher at IA. She was awarded a first degree in PHYSICS/ASTRONOMY by the University of Porto in 2003 and a PhD by the University of Warwick in 2008. She is a member of IA since 2015.
Current research interests focus on the discovery and characterisation of planetary systems. In particular she participated in many ground based and spaced based transit surveys: WASP, CoRoT, Kepler and K2 and contributed to the discovery and characterisation of tens of exoplanets. She is also involved in future missions for transit search and characterisation like CHEOPS, PLATO and ARIEL and high resolution spectrographs ESPRESSO and NIRPS. Combining the high precision light curves obtained with the space mission with the radial velocities measure with the spectrographs will allow to characterise planets down to the earth size up to the habitable zone of their stars.
She has contributed for the COROT imagette pipeline and she has developed a pipeline to reduce and correct systematics in the light curves from the K2 satellite. She also developed a Bayesian transit fitting code to derive transit parameters, in particular transit times that can be used to study the dynamics of planetary systems.
