Research

My main area of research is stellar atmospheres, and the solar atmosphere in particular. Most of the light that reaches us across the universe comes from the atmospheres of stars, making them an essential component in astronomy. In my work I enjoy combining observations of the solar atmosphere with cutting-edge simulations of this dynamic layer, and learning something in the process.

Current research

Presently, I work on observations and modelling of the solar chromosphere, a thin but precious layer that is sandwiched between the bright solar surface and the million-degree corona. I am a part of the science investigation of IRIS, a NASA satellite that aims to study how mass and energy flow through different layers of the Sun's atmosphere. Among other things, I have studied the diagnostics from the NUV window of IRIS, and use them to learn about the energy transfer across the solar atmosphere and the dynamics of the solar chromosphere.

Previous work and positions

• NASA ARC and LMSAL (Palo Alto, CA, USA): NPP Postdoctoral fellow. Worked with Bart De Pontieu on chromospheric dynamics and the diagnostics of IRIS
• ANU, RSAA (Canberra, Australia): Postdoctoral fellow, PhD Student. Worked with Martin Asplund on 3D models of the solar photosphere and the solar oxygen abundance.
• ISF, KVA (Stockholm, Sweden): Research trainee. Worked with Dan Kiselman on solar observations and data reduction pipelines for 2D spectroscopy.
• CENTRA, IST (Lisbon, Portugal): undergraduate student. Worked with Ilidio Lopes on asteroseismology of dwarf stars, solar interior models and dark matter.

Publications

You can find my publications on ADS using my ORCID: 0000-0003-4747-4329. Most papers should be open access or freely available, but I'll be happy to send you a copy if there is one you cannot access.

My PhD thesis is available from the ANU Digital Theses.

ESPOS

Together with a bunch of like-minded enthusiasts, in 2017 I started the European Solar Physics Online Seminars (ESPOS), a regular series of streamed seminars.
