I aim to detect and characterize extrasolar planets, defined as planets orbiting stars other than the Sun.
Today, the two main techniques to detect exoplanets are the transit and the radial velocity (RV). These two techniques are complementary since the transit allows the determination of the planet radius and the RV its mass. Hence, combined together, they inform on the nature of the planet (e.g., rocky, gaseous).
The difficulty of detecting exoplanets by these two techniques increases as the planet becomes small and less massive.
With the modern high-precision instruments, detecting planetary signatures is now limited by the stellar intrinsic variability. Stellar activity can hide or mimic the signatures of Earth-like planets. In this context, my field of expertise consists in developing new detection tools to disentangle the planetary signatures from this stellar activity.
