Biofilms dans un micro canal

Our group is contributing to the scientific revolution that aims to minimize negative environmental impacts of anthropogenic emissions. Our goals of doing more with less are facilitated by new technologies for studying microscale chemistry.

Our specific research directions include: (i) development of new microscale-compatible spectroscopic methods, (ii) synthesis of catalytic biomaterials, and (iii) high-precision micro-scale chemistry with energy and environmental applications. To facilitate this work, our group develops and uses state-of-the-art tools in microfluidics, spectroscopy, electrochemistry and nanoscience.

We are located at Laval University, Canada's oldest university, in the traditionally strong and innovative chemistry department. We are always looking for highly qualified and motivated students and research professionals who have demonstrated their excellence through academic publications and external funding.

We are proud to be members of the following strategic research initiatives: Nano Ulaval, Québec Centre for Functional Materials (CQMF), Centre for Advanced Materials Research at Laval (CERMA), Biophysical Society of Canada (BSC), Central Hospital of Québec Research Centre (CHUQ) and Institute for Biomaterials and Bioengineering (iBiomat).

Jesse Greener presents an overview of our group's work to the Waterloo Institute for Nanotechnology: "Bacterial Biofilm Research Renaissance by Combining Nanoscience and Microfluidics"

Thanks to all the participants to Laval's first annual microfluidics symposium. Special thanks to Professor David Juncker for his invited lecture.

Halifax was the site of another successful ICASS meeting. Professor Greener warmly thanks all participants to the session on micro/nano imaging of biological and materials. In addition, the first Advanced imaging workshop was successfully added to the conference. Click here for a copy of the power point presentation.
