Senior Research Scientist specializing in R&D microbiology, with a Ph.D. in veterinary science and deep expertise in biofilms. Currently leading the microbiology laboratory at SPARTHA Medical, where I develop antimicrobial coatings and hydrogels for medical devices. My research spans biofilm architecture, pathogenesis, and innovative treatment strategies. An inventor with multiple patents, I have also held research positions at Humboldt-Universität zu Berlin (Germany) and the University of California, Santa Cruz (USA). In addition to my scientific work, I am a writer and dedicated educator, actively contributing to the academic community through publications, teaching, and workshops.
Investigated Helicobacter pylori biofilm formation and its potential role in pathogenesis.
Employed transcriptomic and genetic approaches to identify genes involved in biofilm development.
Utilized mouse models of H. pylori infection to study in vivo biofilm behavior.
Applied confocal scanning laser microscopy (CSLM) and scanning electron microscopy (SEM) to characterize biofilm structure and composition.
