Intern Exoplanet Group (Leiden)
Netherlands Institute for Space Research (SRON)
Exoplanet Atmosphere Characterization: assessing the impact of inhomogeneous datasets on comparative planetology. In this internship I show that assuming space-based instrument comparability for exoplanet atmosphere retrievals biases the retrieval results. Further, my findings indicate the offset between space-based instruments can be as large as between ground- and space-based instruments, even between mature instruments on the HST. These findings have implications for our current understanding of exoplanet atmospheres and the science from instruments such as ARIEL and JWST.

Systems Engineering Intern
Rocket Factory Augsburg (RFA)
As a systems engineer at RFA I was responsible for the performance & evolution analysis, mass budgeting and cost-estimation of the RFA ONE launch vehicle and high-level design of future launch vehicles. I was responsible for the initial idea and design of the debris de-orbiting end-of-life mission of the Orbital Transfer Vehicle. I also worked on the upper stage (stage 2 & kick-stage, now called Redshift) reaction control system, designing the thruster clusters and their feed system.

Helmholtz-Zentrum Berlin for Materials & Energy (HZB)
- CAD (SOLIDWORKS)
- CFD (COMSOL)
- 2012.11 - 2012.11
High-resolution Spectroscopy and Polarimetry Intern
Leibniz-Institute for Astrophysics Potsdam (AIP)
I helped to test & calibrate the fiber optics and prisms of the Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) for the Large Binocular Telescope (LBT)
- Monolithic echelle grating and VPH grisms
- Optic fibers
Volunteer
