In my position as a staff NLP engineer in Logically AI, I spearhead a dynamic project team, focusing on AI for Social Good initiatives in the realm of misinformation AI. I specialize in evidence-based fact-checking, employing advanced computational methods for rumor resolution, assessing information credibility, and conducting automatic analyses of disinformation, including coordinated and inauthentic behavior, propaganda, and persuasive techniques. From a computational perspective, I address challenges related to online threats, influence dynamics, and the broader landscape of fake news. My work also involves navigating the intricacies of human-and-model-in-the-loop processes to ensure comprehensive and effective outcomes.
My main research interests are LLM/generative AI, knowledge representation, statistical NLP, NLP-based machine learning modelling, weakly supervised learning, and Semantic Web with applications including semantic search, information extraction, information retrieval and knowledge base systems.
I was a research associate at the University of Sheffield, Department of Computer Science (2014 - 2020), affiliated with OAK Research Group (now Pervasive Computing) and work in the general areas of Natural Language Processing, Machine Learning, human mobility tracking (urban and fine-grained/dense scenario) and large-scale information/data processing. My work in Sheffield was funded by numerous EU FP and UK government projects involving multi-national and multi-sectoral partnerships cross research institutes, government and industry. During the period, i was also serving on the program committee as reviewer for a number of academic journals / conferences / workshops, such as Journal of Natural Language Engineering, Journal of Intelligent Systems, PLOS ONE, ESWC, USEC, etc.
Prior to 2014, I was working as a KTP associate as part of a project funded by Innovate UK in Cognitive Computing Research Group, University of Westminster and ActiveStandards (now acquired by crownpeak), mainly carrying out R&D for new semantic systems and services on ActiveStandards platform. Prior to that, I was studying Web Technology in the University of Southampton and was working a senior software engineer (2006 - 2010) for 4 years in a top-5 US-Chinese software service company.
When not obsessing over technology, i can be found outdoors, cycling, hiking, swimming, museum, or art gallery.
