Bo obtained a BSc degree from Beihang University between 2003 and 2007, specialising in Materials Engineering. He then carried out his PhD in Department of Engineering at University of Bristol, between 2007 and 2011, followed by taking two Post-doctoral Research Associate posts in 2011 in Bristol’s High Temperature Centre and then in 2013 in Materials Performance Centre at University of Manchester. In 2015, Bo moved to a Lectureship at Coventry University, being promoted to Senior Lecturer in 2017. He was awarded a 5-year EPSRC Early-career Fellowship in Nuclear Fission in 2018. Bo became a Professor of Engineering Materials at University of Leicester in March 2019.

At University of Leicester, he serves as the Chair of the EPSRC Key Funder Working Group (2022-Current), Head of Mechanics of Materials Group (2020-Current). He acted as the Engineering School’s Director of Research (2020-2022).



Bo has worked for 15 years in the field of high-temperature structural materials performance and has specialised in advanced manufacturing, microstructural characterisation as well as creep and fatigue related lifetime prediction. His areas of research interests include:

  • Creep, fatigue as well as oxidation
  • Residual stresses at different length-scales
  • High-temperature structural integrity assessment
  • Electron beam melting and other powder-bed-fusion additive manufacturing processes (experiment and process model)
  • Physical metallurgy of high-temperature structural materials
  • Titanium alloys and gamma-TiAl alloys
  • Nickel base superalloys
  • Austenitic stainless steels
  • Large scale experimental facilities (neutron and synchrotron X-ray based)
  • Microstructural characterisation using advanced electron microscopy
