Mark Wirth
Materials Scientist

Mark Wirth is a materials scientist with the Terrestrial-Atmosphere Processes team. Since joining EMSL in 2018, he has worked on the analysis of a range of materials using atom probe tomography (APT) and nanoscale secondary ion mass spectrometry (NanoSIMS). He is currently working to develop methods for the application of machine learning to these techniques.
