Dr. Tim Lichtenberg

I work as Assistant Professor at the Kapteyn Astronomical Institute of the University of Groningen in the Netherlands, where I study the growth and evolution of rocky planets in order to embed the birth and life cycle of terrestrial worlds in an integrated picture.


The research of the expanding Forming Worlds research group is connected with the Alien Earths, AEThER, and Large Interferometer for Exoplanets research initiatives, and funded by the Branco Weiss Foundation and the Kapteyn Astronomical Institute.
