His current work focuses on developing solvents and gas-liquid contactors for direct air capture and integrating membrane technology with carbon capture/direct air capture technology.
Dr Song Zhou
- Song Zhou’s research focuses on CO2 mineralisation, i.e. the integration of CO2 capture, utilisation and conversion with solid waste valorisation processing, such as coal fly ash, chloride waste and municipal solid waste (MSW) incineration ash. In addition to intensive lab research, Dr Zhou has rich experience in industrial project management and execution as well as strong leadership. He has maintained connections with industrial partners, such as SUEZ, Latrobe Magnesium, EPA Victoria, and mineral companies overseas.
- Dr Zhou’s research has made significant contributions to the valorisation processing of Victorian Brown coal fly ash, otherwise an overwhelming amount of alkaline solid waste of significant environmental issues, via proposing, validating and confirming a whole flowsheet to obtain highly value-added metals of Mg and Fe. In the meanwhile, the wastes, including CO2 and chloride leachates can be efficiently and effectively utilized and recycled to form a circular-economy. This led to successful fund-raising for his industrial partner, a pilot plant that is being built in Latrobe Valley, and a patent under application. Dr Zhou is also dedicated to flowsheeting, techno-economic analysis (TEA), which is critical for the implementation of any new industrial processes, using Aspen software and CSIRO-developed technologies.

Dr Roger Latham
- Roger Latham joined CarbonLock in February 2023 as a Postdoctoral Research Fellow. He comes with 18 years of experience in microbiology and molecular biology laboratories, and has undertaken commercial, biotechnology start-up and academic projects. His research has covered a large range of organism types and contexts, including bacterial and fungal enzyme production, bioreactors, epidemiology, food spoilage and poisoning, human respiratory pathogens, and fermented food and beverages.
