Simulating Tumour Vasculature at Multiple Scales

I am interested in medical device design and the pathophysiology of small blood vessels in cancer. I develop and apply high performance scientific software to solve challenging 3D, multi-physics problems in these areas. Addressing problems of interest usually requires a range of methods including:
- non-linear solid mechanics of metals (including plasticity, damage and micro-mechanics), synthetic and bio-polymers, and soft tissues (with anisotropy)
- complex contact problems involving large sliding contact with membranes and shells
- agent based modelling of biological cells and blood vessels
- numerical solution of reaction-diffusion systems for chemical (nutrient and drug) transport
- 3D image segmentation and particle tracking
- experiment design and global optimization
- programming for high performance computing (in particular distributed memory parallelism with MPI)
I have recently developed an open source software library for modelling vascualrized tissues https://jmsgrogan.github.io/MicrovesselChaste/ and contribute to the Chaste library for soft tissue modelling http://www.cs.ox.ac.uk/chaste/. I primarily use C++ and Python for development and have experience of all major stages of developing and releasing a (reasonably) large software project, including testing (CxxTest, Travis CI and ctest), deployment (Docker, conda and Debian packaging), cross-platform builds (cmake), version control (git, Github) and documentation (Doxygen, Sphinx, Jupyter Notebooks, web template engines). I have experience building simple, interactive 3D user interfaces for web (XTK, three.js) and standalone (VTK and wxPython) applications and have developed a framework for automated Python wrapping of a large (500k-1 Million loc) C++ codebase (a custom solution based on Boost-Python and Py++), resulting in significant usability improvements with minimal overhead.
