About me

I am a Colombian astronomer with a PhD in Astrophysics from Radboud University, the Netherlands. I investigate the Galactic magnetic field and the turbulent interstellar medium using starlight and dust polarization at the Astronomy and Plasma Physics Division of the Department of Space, Earth and Enviroment at Chalmers University of Technology. I have a M.Sc. by research in Physics and Astronomy from the University of Leeds, United Kingdom, where I also developed an interest in star formation and the chemical evolution of star-forming regions.

Scientific interests

  • The Galactic magnetic field

    Investigating the properties of the Galactic magnetic field using all kinds of tracers of the interstellar medium and the magnetic field.

  • Interstellar medium

    Studying the properties of the multiphase interstellar medium and their interplay with the Galactic magnetic field.

  • Star formation and chemical evolution

    Finding patterns of chemical evolution in the mm-wave spectra of massive young stellar objects.

Starlight polarization, a Galactic compass

Investigating the properties of the Galactic magnetic field and the interstellar medium using starlight polarization.

The Galactic magnetic field runs through the Milky Way, affecting all environments and important processes in the interstellar medium, such as energy balances, structure formation, cosmic ray trajectories, and angular momentum transport. Therefore, investigating the GMF is essential to understanding its role in these processes. The primary goal of this project is to study the properties of the Galactic magnetic field at various distances within the general diffuse interstellar medium using optical starlight polarization observations from the Interstellar Polarization Survey–General Interstellar Medium (IPS-GI) catalog. Starlight polarization from the IPS-GI allows us to better understand the structure and behavior of the magnetized interstellar medium at parsec and subparsec scales.

Finding patterns of chemical evolution in young stellar objects

Complex organic molecules as indicators of chemical evolution are used to classify massive young stellar objects.

Complex organic molecules are the building blocks of life in the universe. They are formed in dense clouds within the interstellar medium and are present throughout every phase of star formation. This makes them valuable for studying both low- and high-mass star formation and evolution. These molecules are observed in the millimeter and sub-millimeter wavelength ranges. Radio interferometers like ALMA enable the observation of several complex organic molecules with high sensitivity and spectral resolution. However, efficient big data analysis methods are essential to processing all this information effectively.
