I am the Director of the Knowledge Media institute, and founder and leader of the interdisciplinary Social Data Science group which researches and applies computational social science methods and social media analytics to model, understand and track various social phenomena on the web. The group brings together expertise in data science, Artificial Intelligence, Semantic Web Technologies, and Social Computing. I have published over 160 scientific papers in various leading journals and conferences, and have taken various roles in the organisation of top-tier scientific conferences, such as the International Semantic Web Conference and The Web Conference. Previously to joining KMi, I was a senior research fellow at the School of Electronics and Computer Science, The University of Southampton.

Current Projects

CIMPLE (2021-2024) CIMPLE stands for Countering Creative Information Manipulation with Explainable AI. The project is funded by CHIST-ERA, and aims to research and develop innovative knowledge-driven solutions for the detection and tracking of online information manipulation while taking into account various AI-explainability needs and requirements.

HERoS (2020-2023) HERoS is an international project that aims to produce epidemiological models for COVID-19 that integrates behavioural dynamics, misinformation spread, supply chain disruption, and governance. The KMi team will be studying the spread of misinformation about COVID-19 in social media and will measure the success or failure of misinformation countering initiatives by multiple sources.

Co-Inform (2018-2021) An international research project funded by the European Commission to study and co-create tools for tackling online misinformation.

NoBias (2020-2022) NoBias is a Marie Sklodowska-Curie Innovative Training Network that aims to understand legal, social and technical challenges of bias in AI-decision making, counter them by developing fairness-aware algorithms, to automatically explain AI results, and document the overall process for data provenance and transparency.

Past Projects
TRIVALENT (2017-2020) EU H2020 project to develop advanced methods for detecting and measuring violent radicalisation behaviour on social media. The project involves collaboration with a dozen European Law Enforcement Agencies.

COMRADES (2016-2019) a European H2020 project to research and develop a collaborative platform for supporting communities during crises, which incorporates automated methods for processing and linking of crowdsourced information and for safeguarding communities during critical scenarios from inaccurate, distrusted and fragmented information posted about the crises on social media

DecarboNet (2013-2016) EU FP7 project to develop platforms for raising collective awareness and influencing behavioural change using a suit of socio-technical strategies and techniques.

Sense4Us (2013-2016) EU FP7 project that aims to develop tools and techniques to enable policy makers to gather, integrate, and analyse policy-related discussions and networks on social media.

ReelLives (2013-2016) EPSRC project that aims to develop filmic representations of social media content for individuals and groups using a mixture of semantic, content, and network analysis and narrative generation techniques.

ROBUST (2010-2013) The objective of ROBUST was to analyze, manage and care for online communities, in order to support their well-being, measure their created values and exploit the knowledge and information contained within.

WeGov (2010-2012) EU project WeGov developed a toolset so full advantage can be taken of well-established social networking sites when engaging citizens as part of governance and policy-making processes.

TAGora (2006-2009) This EU-funded project helps to define Semiotic Dynamics, a new field that studies how semiotic relations can originate, spread and evolve over time in populations. It investigates web-scale collaborative tagging behaviour to further our understanding of the dynamics of information in online communities.

OntoMediate (2006-2009) Aims to explore the extent to which collaborative environments can be used to support the identification of mappings between ontologies.

BioOntoSearch: A three-month project funded by the Leverhulme Trust to investigate searching and ranking of biomedical ontologies at the Stanford Medical Institute
