1. Developed rain attenuation correlation model demonstrating 70% correlation between GSO–NGSO Ka-band downlink paths: ITU-R S.1323 revision proposal accepted at ITU WP3M Geneva (Feb 2025) and by BnetzA. 2. Requirements Engineering for GOVSATCOM/ IRIS²: Designed and evaluated structured interview for 65 national BOS orgs. (Bundeswehr, Polizei); submitted report to EUSPA. 3. End-to-end usability testing of GMV's GOVSATCOM Booking Tool; delivered structured improvement report leading to adoption across g

1. Developed handover algorithm for NGSO constellations achieving 13% throughput improvement and 35% reduction in handover rate over baseline under high interference. 2. Demonstrated 10% throughput gain for NGSO (Starlink, Kuiper, OneWeb) through spectrum coordination between competing NGSO constellations in Ka-band. 3. Implemented conditional handover for OneWeb, restoring service availability from 75 % to 100% for ground station Miami. 4. Authored 4 peer-reviewed technical reports published in IEEE tr

Developed elliptical and circular orbit-tracking and mobility modules for RWTH's in-house Satcom simulator, enabling time-synchronised handover studies for LEO/MEO/HEO.

Developer in project Aperol, an autonomous driving project sponsored by Federal Ministry of Transport and Digital Infrastructure (https://www.ice.rwth-aachen.de/research/projects/aperol). Tasks completed: 1. Migration of middleware used in Baidu's Apollo framework, from CyberRT to ROS. 2. Testing and documentation of Apollo's perception module, especially object detection using YOLO, camera calibration and depth estimation.
