He is interested in using strontium isotope in teeth to decrypt mobility and past migrations, but also in the use of stable non-traditional isotopes and elemental ratios to investigate trophic chains and diet histories. Prof Lugli is involved in the development of novel methods for high precision and resolution laser ablation ICP mass spectrometry analyses of phosphates, carbonates, and other geological/biological matrices. He also uses proteomic analyses of bones and teeth by LC-MS/MS and MALDI-ToF-MS, to unravel the taxonomy and the sex of fossil remains. He was also a Marie Skłodowska-Curie Research Fellow (2023-2024, project AROUSE – Assessing the impact of climate fluctuations on hibeRnation phenOlogy USing novel dEntal biomarkers) at the Institut für Geowissenschaften of the Goethe-Universität Frankfurt (Germany).
