About
My Research
I am a professional astronomer, working as Assoc. Professor at the Department of Astrophysics at the University of Vienna.
My research is devoted to the observational study of the early stages of star formation in molecular clouds. Using state-of-the-art radioastronomical facilities such as ALMA, I investigate the gas dynamics and internal structure of the gas in the Interstellar Medium (ISM).
Four main questions drive my research:
Which physical processes control the formation of stars in molecular clouds?
How does the transition between diffuse and dense gas occur inside clouds?
What is the internal structure of low- and high-mass filaments?Â
Is the star formation process universal?
