Puji Lestari is a professor of air quality management and atmospheric chemistry at the Faculty of Civil and Environmental Engineering (FCEE), Bandung Institute of Technology (ITB). She received her Ph.D degree in environmental engineering, majoring in air pollution from the Illinois Institute of Technology, Chicago, USA in 1996. She is currently appointed as the Chair of the Research Group on Air and Waste Management of ITB. Her research interest includes air quality monitoring and modelling, aerosol characterisation and speciation from different sources, including biomass burning, emission inventory and source apportionment. She also conducts research on emission characteristics from various sources such as transport, residential cooking, biomass burning (agriculture and peatland burning) and industries burning waste and biomass. Since 1999, Dr Lestari has been leading as a project investigator for many national and international research projects on air quality and atmospheric chemistry. She also has many peer-reviewed publications and many international collaborations with many international universities and research institutes, such as the Asian Institute of Technology (AIT), King’s College London (KCL), Dalhousie University, the University of Tokyo, US NASA, NIES-Japan, WRI and ICCT-USA. In 2018, she was invited to serve as a panel member of the Development Methodology for GHG Emission Reduction Strategy in Indonesia and become an expert panel member of the IPCC in developing the emission inventory methodology for SLCP. She is also involved in many professional organisation activities, such as 7-SEAS, IGAC Mango, IBBI, PII, CAI Asia, etc. In 2023, she established the Indonesia Aerosol Association (IAA) and became the first president of IAA.
