Sensing with light

The members of the Photonic Biosensing Laboratory create optical systems that can detect minute quantities of specific molecules in samples from patients, animals, plants or the environment. Our goal is to create point of care rapid diagnostic technologies and highly sensitive systems for environmental sensing.

We are located in the Department of Electrical and Computer Engineering of McGill University.

Research Interests

  • Plasmonically driven polymerase chain reaction (PCR)
  • Resonant cavity optical biosensors
  • Optical nanoparticle design for photothermal cancer therapy
  • SPR and LSPR optical biosensors

Projects

SPR and LSPR

Developing new techniques to maximise information from SPR and LSPR measurements

Photothermal Therapy

Using laser light to destroy tumours

Resonant Cavity Sensors

We are developing techniques to interrogate these devices in the time domain, opening the way to portable biosensors

Ultra-fast plasmonic PCR

Accelerating the polymerase chain reaction using light for rapid detection of bacterial and viral infections.

Openings

Every year we recruit new students for Masters and PhD degrees who are keen to apply their photonics expertise to the exciting and multidisciplinary problem of biosensing. We seek students who enjoy hands-on experimentation and who also have good theoretical skills and the ability to undertake numerical modeling. Students must also be willing to engage with biologists, medical researchers and chemists. Most new students start in September each year, but we also sometimes take new students on in January. Departmental deadlines and application information are available here. If you are interested please send an email to the laboratory director with your CV and a recent transcript.
