Thibault Bertrand, PhD

Dr Bertrand is a Senior Strategic Teaching Fellow in Applied Mathematics and Mathematical Physics in the Department of Mathematics at Imperial College London. Trained as a theoretical physicist, his expertise is in non equilibrium statistical mechanics and soft condensed matter.

Before moving to the Department of Mathematics at Imperial College London in 2018, he was a postdoctoral fellow with Dr Raphaël Voituriez at Sorbonne Université (Laboratoire Jean Perrin). Thibault was trained in the Department of Physics at Ecole Normale Supérieure de Cachan for his undergrad obtaining both a BSc and a MSc. In 2016, he graduated with a PhD from Yale University (New Haven, CT, USA) where he worked on jamming in model disordered systems under the supervision of Prof Corey S. O'Hern (Yale) and in collaboration with Prof Mark D. Shattuck (CCNY). He is the recipient of the Harding Bliss Prize from Yale University and the President's Medal for Teaching Innovation at Imperial College London.

Current group members


Eloise Lardet

PhD Student

Eloise joined the group as a PhD student in 2022, funded by a President's PhD Scholarship, after finishing her MMath degree at the University of Edinburgh. She had previously completed a research project in the group as part of the Mary Lister McCammon Summer Research Fellowship at Imperial in 2021, looking at phase separation and pattern formation in pigment cells. She is now continuing her research on collective behaviour in active matter to understand various biological phenomena (e.g. flocking and intercellular interactions) and explore the fundamental physics in these non-equilibrium systems.


Callum Britton

PhD Student (co-supervised with Dr Gunnar Pruessner)

Callum completed his MSci in Mathematics at Imperial College London. He previously did an Undergraduate Research Opportunity as part of the group in 2021, and has most recently completed his Master’s thesis with Dr. Gunnar Pruessner in the Non-Equilibrium Systems group focusing on the Doi-Peliti field theory of Transiently Chiral ABPs. He continues on as a PhD student exploring active systems numerically and analytically under the co-supervision of T. Bertrand and G. Pruessner.


Yuxin (Tina) Jia

PhD Student

During her undergraduate years, Tina immersed herself in Applied Mathematics at the University of Waterloo, Canada. She then joined the University of Oxford, focusing on Mathematical Modelling and Scientific Computing. In the past, she has studied models of avascular tumor growth and hydrodynamic microswimmers in low Reynold environments.Tina joined Imperial College London in Autumn 2023 as a PhD student; she will study the transport of active particles in complex environments. Ultimately, she is interested in the use of microswimmers as targeted drug delivery systems, with the aspiration of transforming cancer treatment methodologies.


Ross Monaghan

PhD Student

Ross joined the group as a PhD student in September 2024. His main research focus is on the behaviour of active systems for the purposes of understanding biological phenomena, including the collective dynamics of tissues. Previously, he completed an MPhil from the University of Adelaide studying the dynamics of non-equilibrium quantum systems.
