Analytical Exposure Science & Environmental Health Laboratory

 
 

RESEARCH

Our goal is to protect and promote human health by providing a healthy environment.



The Analytical Exposure Science and Environmental Health Laboratory (AESEHL) or Barr/Ryan Lab operates within the top-ranked Environmental Health (EH) Department of the Rollins School of Public Health, ranked 6th among public health graduate programs in the U.S.

Our primary work involves developing methods & assessing exposures to commonly used chemicals (i.e. pesticides, flame retardants, plasticizers, heavy metals, etc.). Researchers in our laboratory developed the first method to measure poly-brominated diphenol ethers in human brain tissue, the first method to measure melamine in urine, and the first method to analyze the herbicide atrazine and its metabolites in biological samples. AESEHL is one of only three laboratories in the U.S. that utilize tandem mass spectrometry-based methods in EH research; with AESEHL housing five mass spectrometry-based instruments: GC-MS with CI, GC-MS/MS with EI, LC-MS with ESI, LC-MS/MS with ESI and ACPI, & ICP-MS.
