Susan leads a programme of research into large scale data analytics and the role of novel data in developing sustainable transport policy. Her current interests lie in understanding the wider impacts of ICT enabled mobility infrastructure (such as health, energy and carbon impacts) and understanding incentivisation as part of behaviourally orientated demand management. She is Co-Investigator for the ESRC Consumer Data Research Centre (CDRC) and a Co-Director of the Leeds Institute for Data Analytics (LIDA) Societies community. Susan is a statistician by discipline and in TRACK, leads the WP3 team on understanding the demographic using public transport, public perceptions and behavioural models.  

‘I lead work package 3, which is concerned with understanding the demographic using public transport – who is travelling, when, for what purpose and how does their perception of risk influence their choices and behaviour.’

Dr Simon Parker

Senior Principal Scientist and Fellow

Simon has a background in exposure assessment modelling for chemical and biological materials. I specialise in fluid dynamics, aerosol science, compartmental models and transport systems.

‘I am the technical lead for development of the mathematical quantitative microbial risk assessment (QMRA) models within Dstl. I work alongside colleagues at Dstl and the University of Leeds to understand viral exposure in different transport scenarios. I also link into the work with colleagues in other WP to make best use of supporting information for the risk model.’

Dr Daniel Miller

Senior Scientist

Daniel is a Senior Scientist at Dstl with a focus on ventilation, dispersion and fluid dynamics. Since the onset of the pandemic he has been focussed on mitigating transmission of SARS-CoV-2 in indoor environments through Dstl’s contribution to the TRACK and NCS PROTECT projects.  

‘My role within TRACK primarily focusses on building and analysing quantitative microbial risk assessment (QMRA) models to help understand how people’s risk is influenced by a wide variety of mitigations and behaviours.’
