I'm an applied research scientist at Thomson Reuters. I recently defended my PhD from the University of Waterloo, where I worked on information retrieval projects. Prior to that, I was an MMath student at UWaterloo. My research is focused on understanding, modeling, and visualizing user behavior with search systems. I'm also interested in high-recall document retrieval.

Since 2013, I have written internal and hobby projects in Python and Django Framework. Some of my code is open-source and available in my Github account.
