Biography

Dr.-Ing. Xiaolei Liu (PhD/MSc/PGCert/BEng/CEng/MIMechE/FHEA/P2P) joined the University of Glasgow in December 2018 after holding the post of Research Fellow in Mechanical Engineering at Cranfield University. His academic profile was previously developed at the Faculty of Energy and Economic Sciences, Technische Universität Clausthal in Germany. His expertise has been deepened in a broad area of Mechanical Engineering, mainly in the fields of Energy & Power Engineering, with a focus on renewable energies & fluid mechanics through advanced experiments and high-effective programming/modelling. 

In the last a few years, his computational work has been extended to data science/mining based on machine learning and deep learning established by various intelligent frameworks (such as Scikit-Learn, TensorFlow, and Keras). Recently, his research is concentrated more on investigations of wide-ranging engineering challenges in faults detection/prediction through digital signals, wind power forecasting, and multiphase flow regime identification.

To be involved in the energy sector outside of academia, he registers with the Engineering Council (UK) as a Chartered Engineer (CEng) and owns the membership in the Institution of Mechanical Engineers (IMechE). Furthermore, he is a Fellow in the Higher Education Academy (FHEA) and a recognized teacher for teaching and learning in higher education. Also, he is a licensed PRINCE2 Practioner in Project Management. He is the associate editor of Energy Systems (Springer-Verlag GmbH Germany, part of Springer Nature) and have been a regular reviewer of several leading journals in the energy sector, such as Renewable Energy, Energy and Applied Energy. He has also been invited to organize a few international conferences in the renewable energy sector.
