Analytical Research

Dr. Michael Freund

We work at the interface between electronics and and chemistry focusing on the synthesis of new nanomaterials for sensing, electronics and energy conversion. Our work ranges from fundamental studies on structure property relationships to applications in emerging technologies. Research in this area involves exposure to leading edge synthetic, electrochemical, surface science and micro-fabrication techniques.

Dr. Kathleen Gough
My primary research focus is spectrochemical imaging of heterogeneous samples, from biological tissues (Alzheimer disease brain, stressed tendons) to diatoms and composite polymers. We use both FTIR microscopy, with Focal Plane Array, and Raman Microscopy. Image at left shows a senile plaque in AD brain, ~20 microns diameter, imaged with FTIR, at 1 micron pixel resolution.

Dr. Hélène Perreault

Our laboratory uses mass spectrometry, especially matrix-assisted laser desorption/ionization (MALDI), to study the composition and structure of proteins, glycoproteins and oligosaccharides. Glycans found in antibodies are a main focus area and for these we develop sample preparation techniques using pull down, chromatography and electrophoresis to make samples amenable to mass spectrometry. We also use electrospray ionization (ESI-MS).

Dr. Gregg Tomy

Research in the Tomy group focuses on developing analytical methods to measure chemicals used in commerce that have the potential to be persistent, bioaccumulative and toxic. We use high resolution mass spectrometry to unearth previously unreported chemicals in the environment.
