Stephen Ingram <sfingram (at) cs.ubc.ca>
I am a PhD student of computer science at the University of British Columbia where my advisor is Dr. Tamara Munzner. My research is in information visualization and dimensionality reduction. Additionally, I work as a research consultant for Twin Beach Analytics where I help to design and implement quantitative trading strategies.
