Research
My interest in mathematical modelling of branching structures of biophysical systems and their interactions with the environment stems largely from my research during my postgraduate studies in mathematical neuroscience and my work on models of molecular movement in neurons.
PhD studentship
The project involves the development and application of novel mathematical and computational methods in modelling of plant root systems. Innovative mathematical techniques in numerical simulation, model parameterisation and model sensitivity analysis were used to calibrate the root growth density-based model on various genotypes in a range of reference environmental conditions. Results from this work aim to uncover key biological factors and plant traits that can be targeted by breeding.
Key research points: PDE modelling, numerical analysis, optimisation, application of PDEs to image analysis, image analysis pipelines, computer programming, plant image analysis software
Supervisors:
- Dr Lionel Dupuy (James Hutton Institute),
- Dr Glyn Bengough (James Hutton Institute / University of Dundee and
- Dr Mariya Ptashnyk (University of Dundee)
Past research
I am also really interested in different approaches to teaching Mathematics. Being a teaching assistant, STEM ambassador, volunteer, fundraiser and participant in public engagement events and activities events speaking about science and interdisciplinary research in Mathematics to students and to the public performing interactive events led to my personal projects:
- Rootie, the Robin Root on the m-aRt-hS Planet”
- Be a Scientist or Sci-artist”
- LEMMAs: Language – Etymology – Mathematics Meanderings through Art and Science”
