Biography

Dr Gabriel da Silva is a Lecturer in the Department of Chemical and Biomolecular Engineering at The University of Melbourne.

Research Activities
- Environmental engineering
- Combustion and atmospheric chemistry
- Biofuels research
- Nitrosation reactions
- Materials and minerals engineering
- Bioleaching (biohydrometallurgy) 

Dr da Silva’s research interests are broadly in the area of energy and the environment, using computational chemistry techniques and reaction rate theory to model complex reaction networks relevant to combustion and atmospheric chemistry, as well as environmentally important organic reaction mechanisms. The current research focus is directed toward understanding and modeling reaction processes related to the use of biofuels (ethanol, biodiesel, and biomass), allowing us to optimize their combustion and thereby support the uptake of these green, renewable energy-sources. Studies are also underway to model the formation and atmospheric reactions of pollutants like soot, persistent free radicals, and ozone depleting substances. A further area of interest is bioleaching, where naturally occurring bacteria are used to leach base and precious metals from sulphide minerals.
