It started with Who To Follow, and soon after, me and a few team-mates "co-founded" a new product called MagicRecs. I was the lead engineer for MagicRecs and helped it become the largest growth driver for Twitter. In early 2017, I started to focus on a project called SimClusters, which enabled a quantum leap in Twitter’s ability to model user interests and spin up new recommendations products effortlessly. Other important initiatives included company-wide priorities such as Topics, Personalization, and some specific projects in Health. At Twitter, I was fortunate to work with wonderful colleagues who trusted my ability to rise to new challenges. I held the role of a Principal Software Engineer at the time I left, having received multiple promotions during my time at the company. ### Ph.D. @ The Ohio State University Jan 2006 – Jan 2012 My Ph.D. research was in the areas of Community Discovery and Similarity Search in Large Networks. My research was published in the most selective venues of my field such as KDD, SIGMOD, and VLDB. I received the Graduate Research award in 2011, and an Honorable Mention for the SIGKDD Dissertation awards. ### Research Intern @ Microsoft Jan 2010 – Jan 2010 | Bellevue, WA ### Research Intern @ Yahoo!
