High-Speed Optical Diagnostics and Predictive Multiphysics
I develop optical instruments, high-speed experiments, and computational models to study short-lived physical processes. Across laser-induced plasma, droplet dynamics, and multi-megahertz OCT, the same approach connects controlled excitation, time-resolved measurement, and predictive modeling validated against experiment.
Research profile
My research follows a common pipeline: controlled excitation, time-resolved measurement, quantitative reconstruction, physical modeling, and validation against experiment. This makes transient behavior measurable, physically interpretable, and useful for engineering decisions.
01
Experiments and simulations of laser energy deposition, blast-wave formation, plasma-kernel evolution, and ignition in gases and atomized fuel-air mixtures.
02
High-speed studies of droplet deformation, acceleration, and breakup under vortex, shock-wave, and laser-induced forcing.
03
Development and validation of multi-megahertz OCT endoscopy, including rotational synchronization, probe design, controlled pullback, and switchable imaging range.
Selected work
These studies are strong evidence for my combined experimental, optical, and computational work across three stages of my research.
Calibrated droplet experiments, aberration-aware optical modeling, uncertainty propagation, and ECOGEN simulations connect focal placement to propulsion and breakup.

About
I am a research scientist with a Ph.D. in Aerospace Engineering whose work connects optical instrumentation, high-speed flow diagnostics, image analysis, and computational modeling.
My research began with computational fluid dynamics and laser ignition, including development of an experimental facility for laser-induced breakdown in atomized fuel-air mixtures and methods for tracking shock waves and plasma-kernel evolution. I later worked on vortex-droplet, shock-droplet, and laser-droplet interactions, combining time-resolved imaging with physically interpretable models. At the University of Lübeck, I have contributed to multi-megahertz OCT endoscopy through motor-acquisition synchronization, probe design and development, automated pullback, and dual-resolution rectoscopy. Recent first-author work integrates measured breakdown thresholds, aberration-aware optical modeling, high-speed shadowgraphy, uncertainty propagation, and compressible multiphase simulation to predict laser-driven droplet propulsion and breakup. Across these areas, I focus on the same problem: how to design a measurement, model the governing physics, quantify uncertainty, and turn complex transient behavior into a reproducible result that can be interpreted and controlled.
Research collaboration
I am interested in optical instrumentation, high-speed diagnostics, transient multiphase phenomena, biomedical imaging, computational modeling, and reproducible analysis workflows.
