I come from a multidisciplinary background that includes Computer Science, Distributed Systems Engineering, Human Factors Engineering Human-Computer Interaction (HCI) and Cognitive Psychology. During my PhD (PhD Thesis: ""Cognitive Processes and Vehicle Routing Problems (VRPs)"") I investigated cognitive-inspired and human-centred interactive methods for route optimisation working on how to enrich existing computational algorithms (e.g. Tabu search) through the design development and evaluation of an interactive tool for planning and solving VRPs. While completing my PhD I started working as a postdoc Human Factors Engineer (Research Fellow) at The University of Nottingham within the School of Computer Science Horizon Digital Economy Research and the Faculty of Engineering (Human Factors Research Group). My work there focused on HCI research and particularly User Experience (UX), User-centred and Participatory Design, Human Factors and Ergonomics, Ubiquitous Computing utilising mixed-method approaches. I am currently a Lecturer in Human Computer Interaction within the School of Computing and Mathematical Sciences. I am also the School’s Director of EDI and Academic Lead for Early Career Researchers (ECRs) within the College of Science and Engineering. I am also the School's Ethics Officer, a member of the College's Ethics committee and the University's Research Integrity Working Group.
My research interests include the design and evaluation of Socio-Cognitive Artificial Intelligence (AI)-based and Mixed-Reality (MR) technologies to support decision-making User Experience (UX) and problem solving within Transport and Healthcare. I am particularly interested in Human-Data Interaction and ‘human-in-the-loop’ approaches in Automated Data-driven Systems and Services e.g. in Route Optimisation Intelligent Mobility and Joint Cognitive Systems utilising MR and wearables. I am interested in Crisis sensemaking and meta-cognition for designing technologies for enhanced safety performance and UX. Prior projects were funded by RCUK European Commission (e.g. Horizon2020) designing Transport and other innovations. Currently funded projects are the following: UK Trustworthy Autonomous Systems Verifiability Node - https://verifiability.org/ (UKRI) (2020) - £2923653.00 Co-Investigator (Co-I) and Engagement Officer.
