Siobhan is a Senior lecturer in Environmental and Civil Engineering. Her research interests include:

• Whole life carbon accounting in construction, to identify hotspots for reducing embodied and user green house gas emissions from both buildings and infrastructure. 
• Environmental assessment, including life cycle assessment, for assessing impacts of novel concrete products.
• Risk assessment of contaminated sites (including human health risk assessment, the use of bioaccessibility testing and differentiating between geogenic and anthropogenic sources of contamination).
• Remediation of carbon disulphide soil and groundwater contamination.

Prior to starting her research at Queen's University Belfast in  2004, Siobhan worked within Kirk McClure Morton (now RPS Belfast), as a Chartered Engineer for 6 years, working on a wide variety of projects including contaminated land investigation, risk assessment and remediation, environmental impact assessment and design of waste management facilities, including landfill sites and recycling centres.

Siobhan is a member of the Sustainable Practises Committee for the school and is Scholarsips and Prizes Co-ordinator for Civil Engineering.

Siobhan has extensively reviewed how sustainable development and environmental engineering is embedded within Civil Engineering undergraduate programmes .  She teaches the following modules to BEng/MEng Civil Engineering students:

• Civil Engineering in a Changing Environment (CIV3067 20 CATS points).  Siobhan developed this module which was first offered to students in 2021-2022.  It sets out how civil engineering needs to urgently adapt to meet the carbon reduction targets that will mitigate the climate emergency.
• Design and Communications 4 (CIV4012 40 CATS points) undertaken by final year MEng Civil Engineering students. Siobhan acts as a special consultant advising on environmental and sustainability issues, including whole life carbon analysis for infrastructutre and buildings.

Until 2016, Siobhan taught Contaminated land I (CIV8007/4020), a 10 CATS points module that introduced the concepts of contaminated land management and detailed how exploratory investigations and preliminary and generic risk assessments should be undertaken.
