Dr Sari Budisulistiorini

Research interests

My research interest lies in the formation and transformation of organic aerosols and their gas-phase sources in indoor and outdoor urbanized areas. I have extensive experience in field observation and laboratory experiments of organic aerosol characterization and the impact of anthropogenic and biogenic sources. I complement these analytical techniques with numerical receptor modelling to understand the sources and transformation pathways of organic aerosol in the atmosphere. Moreover, I have particular interest and expertise in biomass burning aerosols and their impact on health and climate. I also broadened my research to airborne microplastic characterization and indoor sources' impact on outdoor air quality.

I use a wide range of mass spectrometry and spectroscopy to characterize the gases and particles in the air. The technique includes real-time, e.g., Aerosol Chemical Speciation Monitor (ACSM; Aerodyne Inc.), Chemical Ionization Mass Spectrometer (CIMS; Aerodyne Inc.) and Selected Ion Flow Tube Mass Spectrometry (SIFT-MS; Syft), and offline instruments, e.g., Orbitrap Liquid Chromatography Mass Spectrometer (Orbitrap LC-MS; ThermoFisher Scientific) and UV-Vis spectroscopy. I also employ numerical models to derive gas and particle measurement information. The models are the Positive Matrix Factorization (PMF) model for source apportionment, the Extended AIM Aerosol Thermodynamics Model (E-AIM) and the ISORROPIA models for aerosol acidity estimation.
