- Implemented improvements to a dynamic focus-shifting laser system from thesis results, advancing integration into a full-scale processing setup. - Led experiments, calibration, and integration of the dynamic focusing unit into a laser setup; executed proof-of-concept trials under industrial conditions. - Worked closely with the research team, providing technical support and weekly progress updates. - Compiled results into a first-author manuscript now under peer review in a photonics journal.

- Thesis: Characterization, Analysis & Control of a Fast Focus-Shifting Device for Laser Material Processing. - Designed optical setups; characterized device for high-throughput laser processing. Analyzed focus dynamics via ABCD modeling & data analytics to validate accuracy. - Derived an improved system equation and applied adaptive filtering for precision. - Automated waveform generation with Python + AFG integration. Authored 80+ page thesis; Grade 1.1 “Excellent”; results cleared for system integration.

- Automated laser & optomechanics control and data workflows in Python for precision experiments. - Led on-site tech transfer at partner institute; learned operation/testing and integrated at ISE. - Maintained lasers via calibration and sensor tests to maximize uptime and accuracy. - Operated 3D-Micromac dicing tool for laser cutting; wrote operator manual for handover. - Resolved laser/sensor issues independently, showing initiative and precision under tight deadlines.
