Professor Muller has had an extensive and distinguished industrial career, taking up a chair in Chemical Process Engineering in the School of Chemical and Process Engineering, and the School of Chemistry. His academic studies began in Holland in 1983 studying Chemical Engineering at Delft University of Technology, followed by a PhD at the University of Cambridge with Professor John F. Davidson and a postdoc at the University de Technology de Compiegne (Fr). In 1994 he joined Zeneca at Huddersfield (Later Syngenta) where he developed DynoChem, a dynamic simulation package now widely used across the pharmaceutical industry. In 2006 he moved to AstraZeneca helping to bring large-scale thinking to early development through the invention and application of scale-up risk evaluations (SURE) and work on the crystallisation workflow concept. He was involved in continuous processing initiatives in AstraZeneca culminating in project managing the AZ element of the F3 factory, a 30m euro pan-European project, before joining the University of Leeds in 2011.

There are three key themes to Professor Muller’s research interests:

  1. Phenomena
    Mixing, Multi Phase reactions, Unit Processes
    Nucleation, Solidification, Yields stress, Thixotropic fluids
    Flow Field Validation
  2. Modelling
    Mechanistic, Kinetics
    CFD, LES for Flow, 3D Mechanistic
    Development and Scale up workflows and risk assessment
  3. Process Technology
    Flow Chemistry, Slow Flow Reactors
    Work up, Process driven scale-up, Plug and Produce

As the CDT’s Deputy Director, Professor Muller takes primary responsibility for the academic work of the CDT, which covers the following areas:

  • The development and delivery of the integrated MSc including the personal and professional development work, and its compliance with academic regulation at school, faculty, and institutional level;
  • The facilitation of the CDT PhD project allocation process;
  • The co-ordination of the CDT’s academic programme delivery team (module leaders, and core teaching staff);
  • The management of the CDT personnel, such as teaching fellows, and any academic-related posts such as teaching assistants or demonstrators.
