Mass Spectrometry and Laser Spectroscopy

 

Overview

 

The Mass Spectrometry and Laser Spectroscopy group is a diverse team of experts in analytical and physical chemistry with an extensive range of state-of-the-art and novel instrumentation used for fundamental and applied research based around mass spectrometry and laser spectroscopy of complex systems.

Much of our current research focuses on:

  1. Multimodal imaging for chemical imaging of plant-microbial interactions, interfaces, tissues and other complex systems
  2. Nonlinear laser spectroscopy and microscopy of electronic and molecular processes in complex materials
  3. Mass spectrometry for high throughput and sensitive chemical characterization

We specialize in developing and applying the next generation of technologies to probe and chemically characterize complex systems.
