PhD research to investigate the degradation mechanisms of ionic liquids used in electrospray thrusters. The work will involve experimental testing, chemical analysis, modeling, and exploring strategies to improve IL stability.

This PhD project investigates flow dynamics around reusable launch vehicles during their return phase using wind tunnel testing. The research focuses on characterizing fluctuating aerodynamic loads during transonic and supersonic reentry, particularly the dynamics of bluff bodies in counter flow and counter jet. Experimental data will be used to propose and test control strategies to mitigate flow fluctuations. Advanced measurement techniques, including unsteady Pressure-Sensitive Paint (PSP), schlieren, and BOS, will be employed.

This PhD project aims to develop a numerical framework to predict instabilities in axial balancing systems (ABS) of aerospace turbo-pumps. The project will use linear stability analysis within an Arbitrary Lagrangian Eulerian (ALE) approach to capture fluid-structure interactions in compressible, turbulent flow. Numerical predictions will be compared with experimental data to validate the model.

This PhD thesis will experimentally and numerically study the dynamics of cold counterflow supersonic jets. The goal is to predict unsteady phenomena, their spatio-temporal characteristics, and thresholds for occurrence.

This research project examines the environmental impacts of armed conflicts on atmospheric ammonia distributions using satellite remote sensing data. The project will upgrade existing retrieval algorithms for new generation satellites and validate satellite observations against ground-based measurements.

This PhD thesis focuses on minimizing and characterizing polarizing effects in optics for UV spectropolarimeters. The research will investigate polarization in echelle gratings, cross-dispersers, dichroics, and UV modulators to improve the polarimetric accuracy of instruments like the Pollux instrument for the HWO mission.

This PhD project focuses on in-lab validation of key concepts for quantum sensor operation in space. The objective is to develop and test methods for measuring non-gravitational accelerations and handling satellite rotation using an optical test-bed and a dual gravity sensor platform.

This PhD thesis focuses on improving the measurement of the spatial response of cooled infrared detectors. The project involves developing a new optical grating concept for projecting 2D spatial frequencies onto a detector array and optimizing patterns for thermal infrared wavelengths. The student will model physical phenomena, design components, and conduct experiments using the MIRCOS cryogenic test bench.

This PhD will combine models of near-surface processes and exosphere modeling to simulate the diurnal and orbital evolution of Europa, Ganymede, and Callisto's exospheres.

This thesis develops methods for rapid detection and characterization of gravitational wave events from LISA data. The focus is on detecting massive black hole binaries, handling packet-based data transmission, and producing alerts with initial source parameter estimates.

This PhD position focuses on characterizing and modeling the cyclic behavior of a CuCrZr alloy under varying temperatures. The research will involve cyclic testing, viscoplastic modeling, and anisothermal thermomechanical fatigue testing.

This research project focuses on developing higher-power ECRA thruster prototypes (exceeding 500W) and establishing thruster scaling laws. The project will involve theoretical modeling, data analysis from existing prototypes, and experimental characterization of new prototypes.

This PhD thesis focuses on developing new integration paradigms for Schottky-based heterodyne instruments at terahertz frequencies. The goal is to minimize transmission line losses and noise, and to drastically reduce the front-end volume for multi-band and multi-focal element configurations.

This PhD project develops a radiative transfer model to interpret ultraviolet observations of Venus from missions like Venus Express and Akatsuki. The model will combine DISORT and htrdr-planeto approaches to simulate radiative processes in Venus' atmosphere. It will be validated against existing datasets and used to support ESA's EnVision mission, including the VenSpec-U instrument. The work involves collaboration with international teams and short research stays in Japan.

This PhD project aims to quantify methane fluxes in the Arctic using atmospheric inversion and satellite data. The research will evaluate the potential of various satellite datasets and integrate methane flux models with environmental variables to improve understanding of natural methane emissions and their variability.
