 # WolfieKnee.io - A page for David Wolfson

  * I really like the work and approach that [Open Innovations](https://open-innovations.org/) do.
    * I'd like to emmulate their approach and technology stack in any training or personal projects that I do so [Luke Strange](https://open-innovations.org/search/?author=lstrange) was kind enough to point me to this overview of the [Open Innovations Platform](https://open-innovations.github.io/platform/)
    * Of particualr interest is the (Open Data Saves Lives) project.

   * I did a PhD at University of Nottingham and my thesis on [on Biomechanics of shaken baby syndrome](https://eprints.nottingham.ac.uk/11217/) is public so if you want you can read it if you like. To do all the processing of experimental data, and then automate running of computational models I built a RedHat Linux server, learned Perl and Python and then realised that my MATLAB code was so slow that I re-wrote it all in C++... I'm looking for examples of all that code on (very) old backup DVDs at the moment, but I suspect it is Fugly!
