Research in the Ohno lab seeks to develop and apply tools to elucidate the molecular details of the structure, composition, and reactivity of interfacial chemical systems. We are particularly interested in the surfaces/interfaces of aerosol particles as well as bulk liquid (or liquid:liquid) interfaces. This work lies at the metaphorical interface between a range of fields, including physical chemistry, analytical chemistry, environmental chemistry, and aerosol science.

As an experimental physical chemistry lab, we use a variety of different analytical techniques and instrumentation, including sum-frequency generation/second harmonic generation, fluorescence probe spectroscopy, aerosol mass spectrometry, and scanning mobility particle sizing.
