Our research is focused on obtaining a fundamental understanding of the physical and chemical phenomena underlying chemical analysis of complex molecules in complex mixtures. One area of research is focused on understanding interactions between ions and surfaces for controlling activation, dissociation and deposition of complex ions following collisions with specially prepared surfaces. To achieve this goal, we have developed unique mass spectrometry instrumentation for studying physical and chemical phenomena underlying ion-surface collisions. Our studies provide important information for understanding molecular recognition, charge transfer, nucleation, and self-assembly in complex systems. Soft and reactive landing are promising approaches for highly selective surface modification, preparation of novel catalysts, supercapacitors, and biomaterials. 

Another area of research is focused on the development of new approaches for chemical analysis in complex heterogeneous environments. Specifically, we are developing nanospray desorption electrospray ionization (nano-DESI) – a new ambient surface ionization technique for chemical imaging of biological systems in their native state and quantitative analysis of complex mixtures such as organic aerosols, petroleum, and biofuels directly from solid substrates. 

We have also developed new tools for the analysis of complex spectra obtained using high-resolution mass spectrometry. These tools have been used for understanding chemical transformations in organic aerosols providing insights on the relationship between the chemical composition of these complex systems and their possible effect on climate and human health. Finally, nano-DESI imaging has been established as a robust analytical tool for the simultaneous detection and spatial localization of hundreds of lipids and metabolites thereby providing detailed molecular snapshots of the biological processes in tissues and imaging of living microbial and yeast colonies.
