Brossard's early achievements include developing a rapid and precise analytical method for detecting uric acid in urine using EC-SERS for routine diagnosis of early eclampsia and the rapid detection of melamine in milk using a portable and affordable EC-SERS system. The SERS of turmeric allowed its

The
Brosseau research lab investigates the spectra observed when nanoparticles interact with light, to develop green molecular sensors. A green synthesis of silver nanoparticles improved their surface-enhanced Raman spectroscopy. Electrochemical surface-enhanced Raman spectroscopy (EC-SERS) was
435:
In 2007, Brosseau completed a PhD at the
University of Guelph under the supervision of Prof. Jacek Lipkowski on a project which involved using electrochemistry and infrared spectroscopy to probe the interaction of cholera toxin with a model biological membrane supported on an electrode surface.

In 2007, Brosseau received an Andrew W. Mellon
Foundation postdoctoral fellowship to work at Northwestern University under the supervision of Prof. Richard P. Van Duyne, in collaboration with the Art Institute of Chicago. This project used surface-enhanced Raman spectroscopy (SERS) to analyze

Brosseau was born in
Halifax, Nova Scotia, and received a B.Sc. degree in chemistry from Dalhousie University and a MSc degree in 2003 under the supervision of Prof. Sharon Roscoe at Acadia University for studying the adsorption of proteins on metallic surfaces using electrochemical methods.
456:
In 2009, Brosseau joined the
Chemistry department at Saint Mary's University as an Assistant Professor, and was promoted to Associate Professor in 2014. Brosseau was named the Canada Research Chair in Sustainable Chemistry and Materials in 2016.
