2017: Exploiting combined SWIR + TIR retrievals to allow for the determination of the sources of enhanced methane levels over China (Fortran F90, python).2014-2017: One of the initiating members of the GOSAT-TIR working group with the aim to improve the quality of the GOSAT-TIR spectra. Developing sophisticated bias-correction algorithm for GOSAT-TIR channel (Fortran F90, python). Producing non-biased methane retrievals from GOSAT-TIR spectra. 2013-2014: Participant in ESA's SIROCCO ("Synergetic SWIR and IR retrievals of near-surface concentrations of CH4 and CO for Earth and Planetary atmospheres") study. Exploiting both synthetic and actual GOSAT data as a showcase for the capability to retrieve methane profiles from a synergetic retrieval of SWIR and TIR measurements (Fortran F90, python).2013-2014: Developing a L1-L2 processor for the thermal infrared channel of the Japanese GOSAT-satellite (Greenhouse Gases Observing Satellite) within the RemoTeC framework (Fortran F90, C, python).2011-2013: Exploiting TELIS data in collaboration with two teams from Germany (DLR, Oberpfaffenhofen and KIT, Karlsruhe) and one from Japan (NICT, Tokyo). This included L2-L3 processing (Fortran F90 and C) with the aid of a chemical model. 2009-2011: Defining science cases (ozone chemistry and isotopic water dynamics) and measurement/flight plan for TELIS balloon campaigns. Data reduction of TELIS data with a focus on L1-L2 processing but also participating in L0-L1 processing.2008-2009: Deriving instrument requirements from user requirements (Matlab) for the Sentinel 5-precursor mission (TROPOMI).2005-2008: Fully developing and implementing L1-L2 processor (Fortran F90 and shell script) for the stratospheric balloon instrument TELIS.2015-2017: Editor for the news bulletin SRONieuws

Data reduction and calibration of high resolution XUV synchrotron spectra of molecular deuterium (D2), covering the broad wavelength range of 84-111 nm.
