I am a Senior Data Scientist at Walmart. As part of Search: Intent Understanding team, I have designed algorithms and ML models to understand user intent and improve relevance and engagement of the Search platform.
I graduated from Columbia University with a PhD in Computer Science, advised by Profs. Rocco Servedio, Alex Andoni and Cliff Stein. Before joining Columbia, I graduated from the Indian Institute of Science (IISc) with a BS degree in Mathematics in 2016.
