Research Projects

Project AEBIO: AC Electrohydrodynamic Bubble Interface Oscillations
April 2025 and March 2026

68ème & 70ème campagne de Vols Paraboliques CNES (VP183 & VP190)

Designed and engineered the AEBIO platform, a modular, flight-certified experimental system for investigating bubble dynamics in terrestrial and microgravity environments.

Engineered an EHD boiling system with multi-channel thermal sensing.

Developed a synchronized data acquisition pipeline that integrated high-speed videography with real-time electrical measurements and developed custom DAQ software.

Integrated a semi-automated image processing workflow using Python/OpenCV to extract quantitative geometric data (volume, aspect ratio, contact angle) from high-speed recordings.

Decoupled polarization and Coulomb forces, discovering novel EHD phase-locking mechanisms.
