What I work on 
A short summary of my research

Planet formation and evolution
My research follows how planetary systems form, how they change over time, and what material they are built from. I approach this through observations, laboratory-based dust and ice properties, and numerical modelling, with a focus on dust and ice in young protoplanetary disks, in older debris disks, and in comets.


Debris disks
Debris disks are the dusty remnants of planet formation around mature stars. I model how their dust shows up in images, spectra, and polarised light, and what that tells us about the planetesimals and planets in the system. My work covers eccentric disks, discontinuous grain size distributions, and the detectability of water ice at near- and far-infrared wavelengths, including JWST scattered light and 3 µm polarisation. I also work on disk substructures shaped by planets and stellar flybys, the Herschel and Spitzer debris disk catalogue, and predictions for future facilities such as PRIMA, the Habitable Worlds Observatory and ELT/MORFEO. Most of this is done with DMS, my radiative transfer code for debris disks around main-sequence stars.


Ices and chemistry in protoplanetary disks
With JWST, I study the ice and molecular content of young, embedded disks. I lead the JWST ALMA AGE-Pro project on embedded icy disks in Ophiuchus and measure ice composition in Class I and flat-spectrum sources with JWST/MIRI spectral decomposition. I am also a core scientist in the JWST JDISC and high contrast ERS programs, and a senior scientist in the ERC GEPOD project on the global evolution of planet-forming disks.


Cometary dust
As ESA Rosetta/MIDAS Project Lead, I analyse the dust particles that Rosetta collected at comet 67P/Churyumov-Gerasimenko, with atomic force microscopy images at nano- to micrometre scales. This includes the particle catalogue, shape descriptors, pristineness, and now surface roughness, together with the ISSI international team on 67P cometary activity.


Exoplanets
Since 2015 I have been part of the CARMENES consortium, which searches for Earth-like planets around M dwarfs, and I contributed to the discovery of a giant planet around a very low-mass star. I also take part in the JWST Early Release Science program for direct imaging of exoplanetary systems.


Methods and tools
Radiative transfer and SPH simulations, Python and Fortran 90 code development, machine learning, and large catalogue analysis. DMS is available on Zenodo, and my lecture notes on exoplanetary systems and exoplanets are on Zenodo as well.
