Simon Grimm studied physics at ETH Zürich in Switzerland. He achieved his PhD in 2015 at the Institute for Computational Science at the University of Zürich, where he developed several simulation codes for planet formation. After one year as a postdoc in Zürich, he started as Senior Scientist at the University of Bern at the Center of Space and Habitability (CSH), where he worked mainly on exoplanet atmospheric characterisation calculations. He was part of the Supercomputing team of the University of Bern and worked together with research groups in various interdisciplinary fields to improve numerical integration methods.

Since 2023, Simon Grimm works as a senior scientist at ETH Zürich and the University of Zürich on different topics, including Solar System dynamics, planet formation, coupling the interior structure of planets with atmospheric models, and opacity calculations for exoplanetary atmospheric modeling.

Simon Grimm is the main author of the GENGA code, a state of the art GPU N-body code, which is used by various research groups worldwide. A major scientific achievement was the determination of the masses of the seven Trappist-1 exoplanets, via the transit timing variations (TTV) method.

Simon Grimm is collaborating with the Lowell Observatory in Flagstaff, AZ, where he developes a new code for fast asteroid orbital calculation, used to create a publically available asteroid database.
