Dr. Mike Jenkins is a Senior Lecturer in the School of Metallurgy and Materials at the University of Birmingham. He is a research active polymer scientist and thermal analyst with over 20 years of professional experience in these fields, he also leads the polymer characterization and thermal analysis research group. To date, he has authored over 60 refereed journal papers in the area of polymer science. He has edited three books and has been lead supervisor on over 20 PhD and 30 MRes students. He is also co-author on the fourth edition of “Plastics: microstructure and engineering applications”.

Mike has been principal investigator on EU and industrially funded projects worth over £2.7m. Active primarily at the academic-industry interface, Mike has worked with large companies including JLR, QinetiQ, Cytec, Rolls-Royce plc, GSK, Airbus, GKN, Victrex, JCB and TENCATE coupled with collaboration or consultancy with over 80 national and European SMEs.


PhD in Metallurgy and Materials, 1997
BSc in Chemistry, Birmingham, 1992


Mike delivers lecture courses in polymer science across all four years of the University of Birmingham MEng Materials Engineering undergraduate degree programme. He also delivers post-graduate courses in the areas of polymer science and thermal analysis. In 2004, he was awarded a Postgraduate certificate in teaching and learning in higher education; teaching related outputs include books, book chapters & conference papers. Mike also has a long-standing interest in the public understanding of science/outreach and has contributed to materials science exhibitions/activities at the Science Museum, the Royal Armories and England Squash.

Current teaching:

  • LC Non-crystalline Materials I (polymer synthesis, processing, properties and characterisation)
  • LI Fracture, Fatigue and Degradation (polymer degradation)
  • LH Advanced Materials in Sport
  • LM Advanced Polymer Systems


Activity mainly concerns the relationship between chemical structure, processing, microstructure and the physical properties of thermoplastic polymers, and furthermore, how the properties can be influenced by each of these aspects. Beyond the characterization of the primary crystallization process and resulting microstructure in numerous polymers, blends and thermoplastic composites, a significant theme is the analysis of the kinetics and mechanism of the secondary crystallization process using a hybrid technique combining infra-red spectroscopy and differential thermal analysis (FTIR-DTA).

The application of advanced thermal analysis has continued through the use of ultra-fast scanning chip-calorimetry (FLASH DSC). This technique has allows the elimination of the microstructural re-organisation processes that occur on heating in partially crystalline polymers and thereby provide an understanding of the effect of polymer processing without the instrumental artifacts associated with conventional thermal analysis. Other highlights include a broad and systematic evaluation of the use of CO2 in the processing of thermoplastic polymers; the promotion of miscibility, rheological properties (a reduction in chain reptation time), foaming and melting point depression have all be explored.
