Oliver Weeger

Biography:

Dr. Oliver Weeger received his doctorate from the Department of Mathematics of the Technical University of Kaiserslautern in 2015 and his diploma in Techno-Mathematics from the Technical University of Munich in 2011. Prior to joining the Information Systems Technology and Design pillar at the Singapore University of Technology and Design as an Assistant Professor in 2018, he had been a Postdoctoral Research Fellow at the SUTD Digital Manufacturing and Design Centre from 2015 to 2018. Dr. Weeger's research expertise, contributions and interests lie broadly in the fields of computational engineering. In particular, his aim is to develop more efficient computational methods and implement algorithms that facilitate the integration of digital design, simulation, optimization and manufacturing processes, and thus enable engineers to develop of higher-quality products with improved functionality in shorter product design cycles. His research is centered around three core aspects of computational engineering:

  1. Computational methods for solving ordinary and partial differential equations in engineering, in particular isogeometric analysis in structural and continuum mechanics.
  2. Design and optimization methods and their integration into seamless digital design, simulation, optimization and manufacturing frameworks.
  3. Engineering application of computational methods in advanced manufacturing technologies such as multi-material 3D printing of active and multi-functional artefacts, lattice structures and metamaterials, as well as 3D knitting of functional textiles.
