Stock Market Selection Strategies

Posted: July, 2013



This is a D3/Javacript project that enables a user to compare and analyze 82 different stock market strategies using a dataset from the American Association of Independent Investors. The dataset is simply a csv file that indicates the percentage change each month for each of the 82 strategies. Annualized returns, standard deviations, risks, and Sharpe ratios are calculated on-the-fly, client-side, for user-selected time ranges and presented as an interactive visualization with multiple cross-filters.

Spacecraft Orbit Simulation

Posted: December, 2012



When I was working at the Laboratory for Atmospheric and Space Physics, I designed the Science Data Center for a NASA program called the Magnetospheric Multiscale (MMS) Mission. Around that time, I was exploring data visualization using OpenGL and needed an interesting project to play with. Building the 4 rotating MMS spacecraft in code and then using simulated attitude and orbit data to animate them in their orbits became an obvious choice. I never released the code anywhere but I did create a short video showing its capabilities.
