source .venv/bin/activate
pip install .
cd ..
```
To do the build:
``` shell
cd personal-site/src
dialann --build_dir=../build

## 2024 ##
### Marinerg E-Infrastructure - ICHEC ###
The [Marinerg](https://www.marinerg-i.eu/) project aims to build a European distributed research infrastructure for offshore renewable energy. ICHEC are part of a work-package to build the e-infrastructure to support the project, including the design of web portals to support facility access and a data management system. The project is at an early stage, but some of the content is open-source and available [here](https://git.ichec.ie/marinerg-i).
#### Tools ####
* `Django`
* `Angular`
### ICHEC Common Tools - ICHEC ###
Recently at ICHEC we've started building up a collection of documentation and software tools to help us standardize some of our workflows across projects. The documentation takes the form of a [handbook](https://ichec-handbook.readthedocs.io/en/latest/src/frontmatter.html) which has a public version. The software takes the form of a collection of open-source [Python packages](https://git.ichec.ie/performance/toolshed), including functionality for technical report generation, system monitoring, batch task processing on HPC systems and workflow management.
#### Tools ####
* `Python`
* `Jupyter Book`
* `Gitlab CICD`
### Hierarchical Storage Management API - ICHEC ###
As part of the [IO-SEA](https://iosea-project.eu) project for developing next generation exascale storage systems, ICHEC developed an API and implementation for interfacing a collection of diverse storage backends under a hierarchical storage management (HSM) paradigm.
The developed software package [Hestia](https://git.ichec.ie/io-sea-internal/hestia) is a C++ application including Http and S3 client and server implementations and an interface to to CEA's [Phobos](https://git.ichec.ie/io-sea-internal/hestia) tape storage library.
#### Tools ####
* `C++/CMake`
* `Curl`
* `RPM Packaging`

While at [Entrepreneur First](https://www.joinef.com/) most of my activities were related to company building and customer research, however my partner and I did build a snazzy automatic lamp model generator on a 4-day coding binge. This was written from scratch in `Python` with `Blender` and `Cycles` integration in a `Docker` container, while my partner built a `React`/`Node` web platform for it. Im quite proud of this one as it was pulled together very quickly under pressure.

**Image:** A segmented tumour microvessel network and a computer simulation of red blood cells flowing through it (thanks to Dr. Miguel Bernabeu, University of Edinburgh).
The availability of oxygen in tumours affects malignancy and responsiveness to treatments such as radiotherapy. Tumour oxygenation depends on how red blood cells are distributed throughout the microvasculature. Suitable rules for modelling the distribution of red blood cells in the pathological vasculature of tumours have not yet been determined. I worked on studying how red blood cells distribute at branching points in the tumour, and ultimately making better predictions of oxygenation. This study was in collaboration with Prof. Ruth Muschels group at the University of Oxford, Dr. Miguel Bernabeu at the University of Edinburgh and Prof. Tomas Alarcons group at the CRM, Barcelona.

My role here was segmentation of 3D image stacks from mulit-photon microscopy in mice, design of microfluidics chambers for flow experiments, particle tracking for measuring red blood cell flux and help in post-processing and 3D visualization of experimental and simulation results.

**Image:** A simulation of sprouting angiogenesis in a corneal micropocket assay experiment.
Sprouting angiogenesis is a process in which new vasculature is formed. It is of central importance in the diagnosis and treatment of many cancers. It is a complex combination of biophysical processes, which are the focus of much on-going research. I worked on the development and application of open-source software for multi-scale modelling of this process and integration with intravital imaging data, in collaboration with Prof. Ruth Muschels group at the University of Oxford.

The struts of coronary stents are less thick than a human hair. At this size-scale the assumptions of continuum plasticity theory begin to break-down, as metallic grains become comparable in dimension to the the strut. Explicitly modelling individual grains when simulating the deformation of stent struts allows statistical size effects, resulting in unexpectedly low failure strains, to be investigated. I studied the deformation of stent struts using crystal plasticity theory for a range of candidate stent materials, including magnesium.
