I am a Postdoctoral Research Associate in the Theoretical Systems Biology group at Imperial College London. I am employed on a BBSRC grant held by Professor Michael Stumpf and Dr Cristina Lo Celso. The goal of our work is to elucidate the cell-cell interactions occurring within the haematopoietic stem cell niche, during homeostasis and disease.
My research interests extend beyond haematopoietic stem cells into areas including stem cell fate determination, cancer dynamics, and population biology. Successful modelling of such systems has required me to develop tools in dynamical systems, statistical inference, agent-based modelling, and data analysis.
- Mapping the haematopoietic stem cell niche through data and theory
- Stem cell fate choice and lineage specification
- Population dynamics of stem cells and cancer
- Agent-based modelling of epithelial-mesenchymal interactions and their tissue-level effects
- Elucidating the dynamics of the Wnt signalling pathway
- Generalised stability analysis of signalling pathways and phenotypic consequences
During 2014 I was a Postdoctoral Research Associate in the Mathematical Institute at the University of Oxford. From 2010 – 2013 I was a BBSRC funded PhD student; my thesis is entitled Modelling haematopoietic stem cells in their niche. Before this I completed a BSc in Mathematical Physics at the University of Edinburgh (graduating in 2009 with first class honours) and an MSc in Bioinformatics and Theoretical Systems Biology at Imperial College London (graduating in 2010 with distinction).
Outside of research I am passionate about writing, communication, and combinations thereof. I have helped to curate events including the Summer Science Exhibition and Imagining the Future of Medicine. I co-edit a short fiction column at Londonist.
