About
This modular biosensor uses genetically engineered bacteriophages bound to graphene oxide to detect pathogen proteins in under one second, even in complex samples like blood, wastewater, or milk. Antibody-free and low-cost, it offers part-per-quadrillion sensitivity without sample purification. Easily adapted to different targets, the device supports real-time, point-of-need diagnostics in clinical, agricultural, and environmental settings. Its speed, resilience, and accessibility make it a powerful tool for global health, food safety, and outbreak response

I am a Ph.D. student in Molecular Life Sciences at Khalifa University, with a background in Chemical Engineering. My research focuses on antimicrobial resistance, where I am developing surveillance approaches that combine wastewater sequencing with rapid biosensors to enhance the detection and monitoring of resistant bacteria. I have designed an ultra-rapid biosensor that can detect pathogen proteins in complex matrices and presented this work at conferences and exhibitions both in the UAE and internationally. Alongside my research, I contribute as a teaching assistant and have recently submitted my first paper for publication.
