Infectious disease, antimicrobial resistance, food safety and food integrity present significant challenges to public health globally. My research focuses on three main research topics exploiting cutting-edge micro- and nano-technologies to address these global challenges:

1. Synthesis and fabrication of optically-active materials using both top-down and bottom-up approaches to provide high quality plasmonic nanomaterials for biosensing.  
2. Development of nanoplasmonics-based biosensing platforms, including but not limited to SPR, LSPR, SERS, and particle-based detections.
3. Development of point-of-care analyses: we aim to incorporate and transfer molecular diagnostic techniques and nanoplasmonic transducers on to compact lab-on-a-chip formats.
