    Research interests

    My research explores the intersection of photonics, laser technologies, and nanomaterials for advanced spectroscopic analysis. I developed a method for inscribing nanofluidic elements, culminating in a patented photonic gas sensor in 2019.

    In 2020, I founded the 'Direct Laser Writing in Glass' group to push the boundaries of sub-micron structuring for applications in augmented reality, microfluidics, and bulk waveguide designs.

    Since moving above the Arctic Circle in 2023, I have been advancing waveguide-based sensors for greenhouse gases. Recently, our team demonstrated a nanophotonic waveguide engineered to ‘localize light in air,’ enabling CO₂ detection at the level of a single molecule in a billion and achieving the first real-time stable isotope ratio measurements.

    Since 2024, I'm preparing the project on developing a photonics biosensing platform for protein analysis. Ultimately, this technology could revolutionize how we monitor protein misfolding, paving the way for earlier and more reliable Alzheimer's diagnoses.

    I’m excited to welcome collaborators to join me on this journey.
