I am a Senior R&D Scientist and Project Leader specialized in biofilm microbiology, antimicrobial coatings, wound-care materials, biomaterials, antimicrobial peptides, and delivery systems. My work focuses on translating microbiology, surface science, and biomaterials into credible biological evidence for medical materials and product development. I help design and interpret antimicrobial and anti-biofilm testing strategies, including bacterial adhesion, biofilm models, coating validation, cytotoxicity, leaching, accelerated aging, and product-relevant biological performance.

Ph.D. research focused on bacterial biofilms in their natural and host-associated environments, with emphasis on Actinobacillus pleuropneumoniae biofilm formation, antibiotic tolerance, immune response, and phenotypic adaptation within biofilm communities.
The work included development and optimization of bacterial biofilm culture methods, characterization of biofilm mutants, analysis of surface polysaccharide contribution to biofilm formation, and evaluation of antibiotic effects on biofilm development.
GPA: 3.85/4.3
