Profile

Dr. Langstaff gained his first degree in electronic engineering at Southampton University, with a final year project developing an automated test system for characterisation of semiconductor devices produced in the Microelectronics Group. He went on to work in the Microelectronics Group at Southampton, working for the Wolfson Industrial Unit and the SERC funded Design Centre at Southampton there as well as a work with CAD data preparation for Electron Beam Lithography.

He moved to Aberystwyth in 1990 on a LINK funded project to design an Integrated Circuit to implement a Charge Detector Array for applications in Mass Spectroscopy. Following the successful conclusion of the project he joined a project to further develop the detector array concept for applications in Electron Spectroscopy. He was appointed as Senior Experimental Officer to CAFMaD in 2006. His main research interest is the layout of Silicon Integrated Circuits for detectors, taking particular interest in the efficient mapping of function and form. As well as his other duties, Dr. Langstaff is departmental Safety Officer for DMAPS.
