Professor Johann Sienz received the Diplom-Ingenieur (FH) in Mechanical Engineering with specialisation in Aerospace Engineering from the University of Applied Sciences Augsburg, Germany, in 1989, the BEng (Hons) from the University of Central Lancashire, UK, in 1989, the MSc in 1990 and the Ph.D. in 1994, both from Swansea University, UK.

He holds a Personal Chair in the College of Engineering, Swansea University, where he is the Deputy Head of College and the Director of Innovation and Engagement.

He directs the £14.3 Mio ASTUTE 2020 (Advanced Sustainable Manufacturing Technologies; www.astutewales.com), part-funded Welsh Government, five year, four university partnership operation. This is a follow-on operation to the original £26.7 Mio pan-Wales, eight university partnership, five year ASTUTE project that brought together academics and manufacturing companies to collaboratively work on advanced topics in manufacturing in sectors such as aerospace, automotive and medical engineering. This project generated over £200 Mio economic impact for the region. He also directs the EPSRC part-funded, £2.2 Mio industrial doctoral training centre MATTER (Manufacturing Advances Through Training Engineering Researchers), in which future engineering leaders will carry out collaborative research work with industry and will graduate with a doctorate. All his projects involve extensive collaboration with industry in the face of a rapidly changing technology base.

He is a Fellow of the Institution of Mechanical Engineers (FIMechE) and of the Royal Aeronautical Society (FRAeS), and a Member of the Institute of Mathematics and its Applications (MIMA). He is a Chartered Engineer (CEng) and a Chartered Mathematician (CMath).
He is Editor-in-Chief of the International Journal “Applied Mathematical Modelling” as well as being on the editorial board of several other international journals.

Teaching

  • EG-700 MRes Engineering Research Thesis

    The aim of the module is to produce a research thesis, which presents the outcome of a significant independent research project. Following approval of the Project Plan and completion of mandatory safety training and documentation, the student will begin the research programme and subsequently comply with the following: attendance of progress meetings with supervisor(s), as required; submission and approval of supervisor(s) of an interim research progress report; short oral presentation of project progress; and submission of thesis, according to University Regulations. All students are required to submit a thesis by the maximum submission date as set out in the University¿s Guide to Research Degree Candidature current at the time of admission and as stated in the formal Offer Letter; however, it is recommended that students aim to complete the thesis 12 months after starting the programme (full-time students). Following submission of the thesis, an oral examination (viva voce) would normally take place within six months.

  • EG-M33 Computational Case Study for Research Engineers

    The aim of the module is to undertake an in-depth study into the use of computational methods in engineering practice by carrying out a detailed literature survey and state of the art examination in a given topic of specialisation.
