My major research interest is to apply high-resolution N-body simulations to study the formation process of the terrestrial planets. Since my PhD, I realised that relying on orbital dynamics alone is insufficient to solve this mystery. I am glad to be a part of the TRR-170 program to perform interdisciplinary research. This provides me with an opportunity to combine geochemistry with orbital dynamics to study planet formation. Currently I am involving isotopic data from meteorites to constraint formation models of the terrestrial planets. One of the major questions that I would like to answer is how Earth and Mars result in different isotopic compositions and accretion.
