Research

Sustainable transportation and energy systems are key to addressing the environmental challenges we face. Our research aims to quantify the environmental impacts of aviation as well as other transportation and energy sectors, and to advance our understanding of how emerging energy sources and technologies can effect change. We take a multi-disciplinary, systems-level approach to analyse mitigation strategies, which include assessments of sustainable engineering design, alternative fuels, energy-efficient operations, and potential regulatory policies.

Interested PhD candidates and postdocs are welcome to get in touch.

Atmospheric Impacts Of Combustion Emissions Sectors

Combustion by-products from energy, industrial and transportation sectors impact the atmospheric composition, leading to air pollution, nitrogen deposition, and adverse climate impacts. We assess the atmospheric and human health impacts of different sectors and how these impacts spread from the emission location. Since aviation emissions occur at high altitudes, the air transport sector forms a special-interest category for our research, as we aim to understand the unique underlying physical and chemical mechanisms of this sector's impacts.

Aviation emissions and their atmospheric impacts

The transition to sustainable transportation and energy requires a combination of regulatory, operational and technological changes, each of which occur on different timelines. In parallel, the atmospheric composition, governed by a nonlinear system of coupled relations, is evolving due to overall emissions’ and other changes. We are interested in analysing different approaches to sustainable aviation and other sectors, taking into account the evolving atmospheric co-benefits and trade-offs in the overall systems-level optimisation. We primarily focus on the long-term sustainable growth of aviation, inclusive of emerging modes of transport, such as civil supersonic aircraft, as well as the effects of alternative fuels such as ammonia and hydrogen.

Data-driven Environmental Assessments

Increasingly more and better quality observational data are becoming openly available. These include data from atmospheric measurement stations and satellite observations of atmospheric composition, as well as source (e.g. aircraft) activity data. In addition, utilising low cost sensors it has become easier to obtain information tailored to the source of interest, while at the same time enabling crowd-sourcing of data. We utilise this abundant data towards the improved understanding and monitoring of the atmospheric effects of real-world aviation emissions and possible interventions.
