Sara Jabbari is a Reader in Mathematical Biology and School lead for Equality, Diversity and Inclusion. She also sits on the Institute of Microbiology and Infection's Steering Group.

Her research group uses an interdisciplinary approach to understand microbial behaviour, with a particular focus on using mathematical modelling to develop or improve novel treatments for bacterial infections. By combining models with relevant experimental data, they study bacteria from the intra-cellular level up to host-pathogen interactions to identify and refine relevant experimental work with a view to accelerating drug development. Mathematical techniques used include numerical and asymptotic analyses combined with reliable model parameterisation.

Sara has received funding for her research from diverse sources, including BBSRC, MRC and the Leverhulme Trust.


  • PhD Mathematical Biology, University of Nottingham, 2007
  • BA Mathematics, Durham University, 2003


Sara Jabbari graduated from Durham University in 2003, incorporating a year of study at the Université Louis Pasteur in Strasbourg, France. She went on to complete a PhD in mathematical modelling of cell-cell bacterial communication under the supervision of Prof. John R. King at the University of Nottingham.

Following a post-doc position on an international interdisciplinary systems biology project examining biofuel production by bacteria, in 2011 Sara was awarded a Biomedical Informatics Fellowship from the MRC. This has provided her with invaluable laboratory experience for carrying out and designing interdisciplinary projects. Sara was appointed a Birmingham Fellow in 2012 to explore mathematical modelling of medically significant microorganisms. In addition to her role in the School of Mathematics, she is a member of the Institute of Microbiology and Infection and the Healthcare Technologies Research Institute at Birmingham.


Semester 2

LI/LH Differential Equations


Research themes

  • Mathematical modelling, particularly applied to biological systems, e.g. gene regulation networks.
  • The use of asymptotic methods to analyse and simplify mathematical models.
  • Integration of experimental data into mathematical models.

Research activity

 Mathematical modelling of:

  • Novel treatments for bacterial infections
  • The emergence of antimicrobial resistance
  • Gene regulation networks
  • Biological signalling pathways (e.g. quorum sensing)

While most of her group's work centres on bacteria, they also study fungal and viral dynamics, in addition to host responses to disease and inflammation. Fully funded research projects led by Sara include "A systems biology approach to understanding and combating Clostridium difficile infection" (MRC) and "Maths-AIM: A mathematical and experimental approach for the rational assessment of bacterial Adhesion Inhibitor Materials in vivo" (BBSRC). Past and present members of her group include:

  • Dr Paul Roberts (BBSRC-funded mathematics PDRA)
  • Chloe Spalding (EPSRC-funded mathematics PhD student)
  • Will Thomson (EPSRC-funded mathematics PhD student)
  • George Youlden (EPSRC-funded mathematics PhD student, joint programme with University of Nottingham)
  • Emma Keen (BBSRC-funded wet-lab technician)
  • Ryan Kerr (Wellcome Trust-funded PhD student, Antimicrobials and Antimicrobial Resistance)
  • Vicky Hagel (Wellcome Trust-funded PhD student, Mechanisms of Inflammatory Disease (MIDAS))
  • Aliya Alsaleh (PhD student)
  • Cameron Wilcox (Leverhulme Trust-funded PhD student)
  • Sandeep Shirgill (MIBTP PhD student)
  • Rahma Abdulahi (Procter & Gamble-funded PhD student)
  • Teri Parsonage (MRC-funded PhD student, Advanced Interdisciplinary Models DTP)
