About
My name is Mari-Liis Aru (see the pronunciation guide below) and I'm an astrophysics researcher in the area of star and planet formation. Based in the group of Dr. Carlo F. Manara at the European Southern Observatory (ESO) in Germany, my work focuses on analysing the properties of protoplanetary disks—the birthplaces of planets. In particular, I use observational data to study the impact of externally photoevaporating winds on disks. You can read about the ERC-funded WANDA project on the team's website; it's a treat for Marvel fans.
With background in physics, I earned my master's degree in Space Sciences from University of Liège, Belgium. Following my master's, I was selected into a highly competitive programme for young graduates at the European Space Agency (ESA) in the Netherlands. At ESA, my research focused on micro-meteoroids impacting the Gaia space telescope.
Online, you can find me sharing digestible explainers, my journey in science, and tips for students. I aim to bring space exploration closer to general audience with the newsletter I publish here.
Besides astronomy and outreach, I’m an enthusiast for languages: speaking Estonian, English, and rusty French, while learning the basics of Ukrainian and German, and having dabbled in Japanese in the past.
* Mari rhymes with starry, Liis is pronounced like Lee's.
