Dr Kai has 20 year experience in data science research and practice. He has a PhD in Computer Science focusing on query optimisation for large databases. Since then, he has been working on data science problems in a number of domains including intelligence analysis, cyber security, social media, autonomous driving, eScience, and bioinformatics. He believes in integrating human intelligence, such as expert knowledge, with machine intelligence, such as machine learning models, which leads to over 60 peer-reviewed publications and a few international awards. He also enjoys the practical side of data science, from contributing to open-source visualisation software to developing visual analysis software. He led and participated in over 10 data science projects, including short-term consulting projects to multi-year 100+-person international project with over £10 million budget.

Dr Kai Xu's research focuses on Visual Analytics, which integrates data visualisation with analytic techniques (such as Machine Learning and Natural Language Processing) to make sense of large and complex data (such as Big Data). By combining the strength of human cognition and computational analysis, this approach allows analysts to gain insight from Big Data faster and deeper than what was previously possible.
