Hatim Laalej Lang received a MEng degree in Control Systems Engineering in 2007 and a PhD in Control Systems in 2010 for his research on nonlinear vibration control systems of civil and mechanical structures at Department of Automatic Control and Systems Engineering, University of Sheffield. After several years' postdoctoral positions at Sheffield, he initially joined Advanced Manufacturing Research Centre (AMRC) as a project engineer in 2014, was promoted to a technical lead and a Lecturer in manufacturing technology in 2017. His main expertise related to control systems, sensors and data acquistion and the application of these to resolving various manufacturing problems including spindle vibration control problems, condition monitoring for CNC machines and cutting tools as well as adaptive control of machine tools.
