Research

Research Interests:

My interests are broad, from exoplanets to fundamental physics, and my current focus is on precision techniques and data analysis for extra-solar planet detection. I am particularly interested in the detection and characterization of the Earth-like planets closer to the Solar System. These planets offer unique observational to answer fundamental questions such as the origin of life, its prevalence beyond the Solar system and how terrestrial planets form and evolve over time. Me and my team of collaborators are pioneering a new generation of observational campaigns focused on individual stars to ensure robust detection of small planets around red-dwarf stars; starting from the nearest ones and expanding the exploration volume one star at a time. The benchmark campaign is the recent Pale Red Dot project (follow us on the web www.palereddot.org, on twitter @Pale_Red_Dot or dedicated Facebook page), which lead to the discovery of a Terrestrial planet candidate orbiting Proxima Centauri, the nearest star to the Sun.

Observational and data analysis astronomers thrive on data. I participate in a number of consortium and surveys dedicated to the task of detecting nearby worlds including the CARMENES survey, CRIRES+ upgrade, and the Carnegie Astrometric Planet Search. I have also been actively involved in space astrometry missions (GAIA/ESA, Phd Thesis), the SIM/NASA project and the current proposals for a local astrometry mission (M4 & M5 calls) dubbed Theia. I am also proud to have an extensive network of collaborators abroad (mostly on Europe, USA and Chile).

PhD Supervision

This is not an exhaustive list and I would be happy to discuss other project possibilities.

Project Title

New generation of ultra-stable instruments for Exoplanet studies

Detecting the signal of a planet orbiting a star is very challenging. Exoplanet characterization is mostly driven by technical advances enabling unprecedented levels of accuracy. Novel technologies and materials are becoming available. Integration of these new technologies can massively reduce the cost of current instruments or, conversely, produce a breakthrough in new instrumental capabilities such as spatially resolved high-resolution spectroscopy and extreme contrast imaging.
The project will focus on designing and developing new instruments and demonstrate them at available observatories. For full details click here

Precision spectroscopy for detection and characterization of nearby Earth analogs

After 20 years of the discovery of the first planets around other stars, we are now moving from discovery to first attempts of characterization. In particular, nearby stars offer unique opportunities to learn about composition, dynamics and potential habitability of planets beyond the Solar System. Stabilized High Resolution spectrometers are now being designed and built to operate on large telescopes, enabling higher sensitivity towards detection of smaller planets and possible characterization of their atmospheres by detecting subtle effects from mollecules in their atmospheres.

In this project the PhD candidate will develop novel data-analysis to be implemented on new generation spectrometers (CARMENES/CaHa, CRIRES+/ESO-VLT) to achieve first attempts of characterization of potentially habitable planets around low mass stars near the Sun. For full details click here
