Dr. Tim Lichtenberg

  • Email

Tim works as Assistant Professor at the Kapteyn Astronomical Institute of the University of Groningen, where he leads the growing Forming Worlds team. He investigates the growth and evolution of rocky planets in order to embed the birth and life cycle of terrestrial worlds in an integrated picture. Ultimately, he wants to understand the planetary environmental conditions that led to the origin of life on the early Earth, and how widespread such places are in our galaxy.

 

The research of the Forming Worlds team is embedded within the Alien Earths, AEThER, and Large Interferometer for Exoplanets research initiatives, and funded by the Branco Weiss Foundation, the Kapteyn Astronomical Institute, and the Faculty of Science and Engineering of the University of Groningen.

Astrobites – The astro-ph Reader's Digest

 

Astrobites is a daily astrophysical literature journal written by graduate students in astronomy around the world. Its goal is to present one interesting paper per day in a brief format that is accessible to undergraduate students in the physical sciences who are interested in active research. During my authoring activity for Astrobites from 2014–2016 I published a variety of blog articles. Until 2019 I remained active in the Astrobites community in various administrative and supportive roles.
