Throughout my career, I have demonstrated proficiency in presenting complex information to diverse audiences, honed through extensive experience in public speaking and delivering presentations. During my Master’s program, I engaged with the wider public through talks and public forums, sharpening my communication skills.

My time as a lab technician at Invetech Research and Development further developed my software expertise.

In my thesis work, I utilized computer skills for data consolidation, analysis, and research, demonstrating adaptability and proficiency in various technical tasks.

Additionally, my experience managing a research biohazard laboratory underscored my ability to exercise sound judgment in maintaining a safe and efficient working environment.
