  • Vensim

    Vensim is a program to create math based workflows to generate interpretable graphs. It is writted for Mac OS 9, which means that it is old and buggy. I also doubt that the average computer user has used Vensim, so rather than providing a vensim file, I'll provide a screenshot. In this screenshot, I have modeled the "medication level" of someone who is taking a medication of 750mg every 8 timesteps. They also start taking at timestep 4 and periodically excrete a percent of the medication. The image is here.

  • Microsoft Excel

    I have some experience in Microsoft Excel that allows me to create tables and charts that dynamially update as you change information via a friendly interface of objects, such as sliders. One of my first excel documents was to model the spread of disease. This worksheet can be downloaded here.

  • Graphics

    I have intermediate skills in graphic design with many programs such as Inkscape, Adobe Flash, Adobe Fireworks, and basic skills in GIMP. Currently, this website does not have as many graphic elements as I'd like to see, but previous website designs of mine have leaned towards heavy use of graphics.

  • Agentsheets

    I have learned basic skills in Agentsheets which allow me to create simple Agentsheet models. Although I do not use Agentsheets frequently, I still retain the knowledge of how Agentsheets functions. A sample of my Agentsheets expertise can be found here.
