Most notable accomplishments include pioneering efforts in the interfacing of liquid chromatography with mass spectrometry (LC-MS), solving the 1987 Amnesic Shellfish Poisoning incident, and producing certified reference materials (CRMs) for biotoxins. The analytical methods and CRMs that his group has developed are in routine use in regulatory laboratories worldwide.
