I am Postdoctoral Researcher working at Caltech/IPAC
I am an astrophysicist working on planets that orbit other stars than our sun. These objects, also called exoplanets, are extremely difficult to image for two main reasons: 1) they are situated further than 10 thousands of billion kilometers from us and 2) they emit several billion times less light than their host stars. Taking a picture of a planet around a star at such distances is equivalent to spot a mosquito close to a lighthouse at a distance of several hundred of kilometers. This requires state-of-the art telescopes that block the light from the star and innovative techniques of post-processing to extract the light from the planet. My current work consists in improving the performance of telescopes for exoplanet science. I am currently preparing observations of exoplanets with the future NASA James Webb Space Telescope (JWST) project (Hubble Space Telescope successor) that will be launched in space in 2021. JWST will help us to better understand the atmosphere f of exoplanets, which is the first step to find evidence of extraterrestrial life. When not working, I create videos, write/listen to music and I like to go on exciting adventures.
My research focuses on high-contrast imaging in the view of directly detecting and characterizing exoplanets. In this framework, the development of innovative image post-processing methods is essential in order to eliminate the quasi-static speckles in the final image, which remain the main limitation for high-contrast. More generally, I am interested in improving the performance of instruments for exoplanet science, taking profit of data analysis and of the detailed characterization of the instrumental limitations and calibration capabilities. My fields of interest regroup direct detection of exoplanets, image processing, high angular resolution and high-contrast techniques, wavefront sensing and control, simulation, modeling and optical design.
