Research in the Ferguson laboratory is focused on development of novel methods for trace analysis of organic and nanoparticulate contaminants in the aquatic environment. Specifically, the laboratory uses high performance mass spectrometry techniques (e.g. UHPLC-Orbitrap MS/MS) to detect, identify, and quantify emerging contaminants (including endocrine disruptors, pharmaceuticals, and surfactants) in wastewater and drinking water. Another significant research thrust involves the development of sensitive trace analytical techniques for quantifying and characterizing single-walled carbon nanotubes in water, sediment, and aquatic organism tissues. For this work, near infrared fluorescence spectroscopy (NIRF) is used as a primary tool for resolving these novel nanoparticulate contaminants in highly complex environmental mixtures.
