This project will build on recent advances in modeling the nuisance component that corrupts high-contrast total intensity observations, and focus on improving exoplanet detection and characterization using data of cutting-edge ground-based and space-based telescopes.
By combining a physical optics model with a flexible machine learning model, this work can avoid introducing unphysical features in the resulting PSF estimate and explores the temporal coherence of structures in telemetry and the limitations of learning this relationship from data sampled on such different timescales.

The Cherenkov Telescope Array Observatory (CTAO) marks the next generation of Imaging Atmospheric Cherenkov Telescopes (IACTs), offering a sensitivity improvement of up to a factor of 10 over current instruments. Its first prototype, the Large-Sized Telescope (LST-1), is already in operation at the Roque de los Muchach...

MICADO, the first-light near-infrared imager for the European Extremely Large Telescope (ELT), will feature a dedicated high-contrast imaging mode designed specifically for observing and characterizing exoplanets and circumstellar disks. The instrument will deliver substantially higher sensitivity and angular resolutio...

The Extremely Large Telescopes (ELTs), with their large apertures and cutting-edge Multi-Conjugate Adaptive Optics (MCAO) systems, promise to deliver data sharper and deeper than even the James Webb Space Telescope (JWST) across large fields. SHARP is a concept study for a near-IR (0.95–2.45 μm) spectrograph specifical...

Direct imaging of exoplanets is limited by the extreme contrast between the star and the planets, which is mitigated using a coronagraph. However, optical aberrations cause starlight leakage through the coronagraph, producing speckles that obscure the planetary signal. Achieving the required contrast levels demands wav...

The upcoming Japan Astrometry Satellite Mission for Infrared Exploration (JASMINE) in the only specifically designed to survey the Nuclear Region of the Milky Way and obtain high precision astrometry (positions, proper motions and parallaxes) of its stars with which to study its origin and formation mechanisms. The bes...
