# Paul Ohno Environmental Fellow: 2019-2021 PhD, Chemistry, Northwestern University Current Position: Assistant Professor, Department of Chemistry and Biochemistry, Auburn University ![ohno_1.png](/sites/g/files/omnuum10846/files/styles/hwp_4_5__480x600/public/ohno_1.png?itok=VnPDPSas) email *Paul Ohno is a physical chemist studying the physical and chemical properties of secondary organic aerosol particles and the implications of these properties for the climate system.* Paul earned his AB in Chemistry from Princeton University in 2014 and his PhD in Chemistry from Northwestern University in 2019. During his PhD studies, he used laser spectroscopy to measure fundamental properties of aqueous interfaces so as to better understand, predict, and control chemical processes that occur there, like groundwater pollutant capture at the mineral/water interface. As an Environmental Fellow, Paul works with Professor Scot Martin of the John A. Paulson School of Engineering and Applied Sciences and the Department of Earth and Planetary Sciences. Their work focuses on developing and applying spectroscopic techniques to directly determine physical and chemical properties, such as viscosity and diffusivity, of secondary organic aerosol particles while they remain in suspension. Paul is also a 2019 Schmidt Science Fellow. ## Faculty Host [Scot Martin](/people/scot-martin), Earth and Planetary Sciences & John A.
