Carleton Biophotonics Research Group, Department of Physics

Welcome to the CBRG Homepage!

The Carleton Biophotonics Research Group (CBRG) is a Medical Physics Group in the Department of Physics at Carleton University in Ottawa, Canada. Our research program involves the development and application of optical molecular imaging techniques for biological discovery. The goal is to develop optical tools that facilitate quantitative and rapid analysis related to disease detection and monitoring, and have the potential for future clinical and industrial translation.

Research Opportunities

Seeking MSc and PhD graduate Students in Physics and / or Biomedical Engineering for Fall 2019

We are looking for individuals with a strong academic track-record and good hands-on experimental and problem-solving skills in Physics or Engineering Physics to join our research team in Fall 2019. The research involves the development of new optical techniques for rapid disease diagnostics using ultrafast lasers and vibrational spectroscopy.



Develop novel technique based on Raman spectroscopy of oral cavity fluids to detect important biomarkers of health. (This project is funded by MITACS and is in collaboration with an industry partner developing advanced photonic technologies to improve oral health assessment).


MSc/ PhD

Develop optical techniques for “virtual pathology”/ develop compact and portable, hand-held fiber optic probe for detection of skin cancer. (This project is in collaboration with partners at Health Canada and the Ottawa Hospital).

For more information, please contact Professor Sangeeta Murugkar, Department of Physics, Carleton University (
