5-year degree • 300 ECTS

Sep 2016 - Oct 2021 • 5 yr


Grade: 8.71/10, Excellent, Top 4%

Thesis: "Study and implementation of an experimental DC motor control apparatus and investigation of using microcontroller embedded artificial intelligence methods"


Developed an adaptive fuzzy-logic controller that outperformed classical PID for BLDC motor speed control across varying speed conditions. Simulated the controller in MATLAB/Simulink, then built and experimentally validated a full hardware prototype using Arduino and STM32 boards and encoder-based speed measurement, gaining hands-on experience with MCUs, incremental encoders, DAC/ADC interfaces, and oscilloscopes. This was an early example of the concept-to-production engineering approach I still apply today, and the work later formed the basis of a first-author journal publication in Energies and a co-authored conference paper at ICCCES.

• Leading the redesign of thermal control circuitry for the GAHM atomic clock, projected to reduce cavity thermal sensitivity to PCB temperature fluctuations by 10–20%, while streamlining production processes to reduce manufacturing time; the work contributed to a successful Preliminary Design Review (PDR) for an ESA program.
• Owned obsolescence risk management for the GAHM PCBs, using SiliconExpert to flag ~15% of components as obsolete, LTB, or NRND before they could impact production, and qualifying replacements for every affected part.
• Performed quality verification for 5 space-qualified RAFS atomic clocks through thermal-vacuum testing and cleanroom inspection, applying a conservative defect standard that rejected ~35% of clock bulbs for minor visual or assembly flaws.
• Selected the photodiode for a space optical assembly, characterizing three candidate parts across 10 samples each for manufacturing consistency and voltage response, and choosing the SSR720 for the best overall combination of low variation across samples and highest amplitude — reducing sample-to-sample variation by 18% versus the weakest candidate, and unit-to-unit performance risk in production.
• Analyzed test data from a PSI proton-irradiation campaign for a space atomic clock (mRO), decoding a 16-bit telemetry register into 5 critical failure-indicator bits and a fault-classification framework distinguishing self-recovering faults from those requiring reboot; authored the resulting operational user guide for satellite operators.

• Directed the WorldFIP communication card redesign, the most critical card in cryogenic crates, from design through prototyping to 400-unit production. Implemented a Wishbone FSM in VHDL for FPGA-to-FPGA data exchange.
• Designed a low-cost, transistor-based analog PCB, using only transistors, resistors, diodes, and capacitors — across 1,300 units in the CERN accelerator, replacing an FPGA-based solution and eliminating a 20% power-on failure rate. Saved over 100,000 CHF.
• Led the design of radiation-tolerant electronics for High-Luminosity LHC upgrade projects, including new digital I/O cards for cryogenic valve control, with 100 units delivered for deployment in radiated areas.
• Owned two radiation campaigns at CHARM, using an automated MATLAB tester to characterize radiation impact across transistors, MOSFETs, operational amplifiers, and voltage regulators — plus one gamma-ray campaign for materials testing.
• Established an accelerated life testing methodology for ADCs, applying a 50% lifespan reduction per 10°C increase (approximately) to compress years of field aging into weeks of lab testing.
• Designed a high-voltage protection circuit rated to 2.1 kV using thyristor surge suppressors, resolving recurring card damage identified during Electrical Quality Assurance testing.
• Supervised a master's student daily for six months on the preliminary design of an analog card based on a 4–20 mA loop. Separately supervised an apprentice for one year on soldering and testing tasks.
• Coordinated electronics projects for two junior engineers, including a Wien bridge oscillator design.
• Engineered radiation-tolerant 3D-printed piezo valve cases using ULTEM and Accura 25 materials.
• Reduced inventory working time by 60-80% by developing Python automation tools.
