Connah Johnson

Connah graduated in 2022 with a PhD in Mathematics of Real-World Systems. Connah was supervised by Orkun Soyer.

Connah's research interests include spatio-temporal processes that may lead to the emergence of complex biological systems. Attached to the Soyer Group in the School of Life Sciences, Connah's research group are interested in coupling agent-based cell population models to chemically active diffusing baths. These hybrid continuous-discrete models form the basis of their software suite ChemChaste. They apply these models to simulate the dynamics of multi-species biofilms.

  • Society of Mathematical Biology (SMB) Annual Conference (2020-present): Poster presenter on our work developing the ChemChaste package. Won the DILISym poster Prize (2021)
  • British Applied Mathematics Colloquium (BAMC) (2021): Poster presentation, won a poster prize at the joint BMC-BAMC virtual meeting (2021)
  • MathODS Online conference June 2020: Co-organised as part of a multi-university committee of PhD students with the aim to provide UK graduate students an opportunity to present their work and network, in response to the beginning of the Covid lockdown.
  • Awarded a Fellowship to COMPSYSBIO 2019 Winter school Advanced lecture course on computational systems biology held at the Centre Paul-Langevin, Aussois, France.


  • Sessional Tutor (Lead Computer Lab Demonstrator) LF305 Dynamics of Biological Systems (2018,2019): Duties include leading computer labs with the aim of teaching students how to code using Matlab in a third year course in the School of Life Sciences. These classes supplement the lecture course. In addition to leading a subset of lab classes and developing the necessary materials, the leaders of other classes are supported and sit-in exams are co-written and marked alongside the course conveyor.
  • Associate Tutor (Teaching assistant) MA390 Topics in Mathematical Biology (2018): Duties include running support classes for the third year course in the Mathematics department. Supplement the students understanding through working through problem sets and providing additional explanations to lecture materials to reinforce learning.
  • Assistant Tutor (Supervisor) (2018,2019): Duties include marking the assignment of 3 groups of 5 first year Maths and Physics students (2018) and MORSE students (2019). We meet weekly to discuss the assignment work and facilitate the students' understanding of lecture material and support their transition to university and studying university level mathematics.

Other Activities

  • Maths Busking (outreach): After participating in a half day workshop I performed some maths busking (performing quick mathematical "tricks" and puzzles to engage with the public) at the family fun day at Warwick as part of the National Science festival (2019)
  • President Warwick SIAM-IMA Student Chapter (2019-2021) Chaired committee meetings, co-organised the (SPAAM) seminar series for postgraduate Mathematics students at Warwick. Liaised with other UK based student chapters. Produced the annual funding report for SIAM
  • Chaired the Student Staff Liason Committee (SSLC) for the 2017 - 2018 academic year. Set the meeting agenda, chaired the meetings, liased with the Students Union, and produced and edited the Annual report for the Complexity/MathSys SSLC.
  • Member of the MathSys Annual 2018 retreat committee. Assisted with the oranisation of the annual retreat to Hawkshead in the lake district in early May 2018.
