An Elemental Regeneration
Emerging applications in life sciences and environmental analysis are driving renewed interest in the unique properties of ICP-TOFMS – in particular, its ability to detect complete elemental mass spectra from short transient events, such as single nanoparticles.

Prior to moving to Switzerland, I did my PhD at Indiana University in Gary Hieftje’s group, where I studied a new form of velocity-based mass spectrometry – distance-of-flight mass spectrometry (DOFMS). My research into DOFMS was formative, and taught me about mass spectrometer design, construction, and operation. I’ve carried the interest and expertise I gained in velocity-based mass spectrometry to my current work at ETH Zurich, developing analytical methods for the high-throughput analysis of diverse inorganic nanoparticles from environmental samples by ICP-TOFMS.
As I began searching for a postdoc position, I was aware of renewed interest in full-spectrum atomic mass spectrometry, largely because of key applications in biomolecule detection and laser-ablation imaging. The potential encouraged me to join the Günther group, who were central to the revival of inductively coupled plasma time-of-flight mass spectrometry (ICP-TOFMS).
