I work at Bloomberg CTO Office as an applied research scientist (search).
I have a PhD in computer science from the University of Waterloo, with a focus in information retrieval, particularly modeling user behavior with search systems. I also worked on machine learning projects related to efficient high-recall active learning document retrieval and annotation systems, and misinformation in web search.
Since 2013, I have written internal and hobby projects in Python. Some of my code is open-source and available in my Github account.
