I focused on identifying novel beta-lactamases and exploring their genetic diversity and evolutionary relationships. Additionally, I performed transcriptomic analyses comparing 2D and 3D glioblastoma cell culture models to elucidate differences in gene expression and gain insights into tumor biology.
