Satoshi was a Project Scientist with the Russell Group. He focused on characterizing chemical composition and morphology of individual particles using Scanning Transmission X-Ray Microscopy (STXM) with carbon K-edge spectroscopy. Particles analyzed were collected during ACE-Asia, DYCOMS II, PELTI, MILAGRO, INTEX-B, ICEALOT, VOCALS REx, and AeroSCOPE. He also worked on a project to simulate thermophysical and dynamic properties of atmospheric systems containing organic molecules by molecular dynamics. Past projects include sample collection and analysis of FTIR organic functional-group composition of PM1 particles from Mexico City (urban location) and analysis of particle heterogeneity and oxidation state of iron in indiviual particles by STXM. He is now an Assistant Professor of Atmospheric Chemistry and Quality of the Air at the School of Architecture, Civil and Environmental Engineering (ENAC) at Ecole Polytechnique federale de Lausanne in Lausanne, Switzerland.
