Hello, thanks for visiting.

I am currently a 2nd(1st) year PhD student at the IRLab, UvA, supervised by Prof. Maarten De Rijke and Prof. Harrie Oosterhuis. I am working on the problem of: Unbiased learning to rank from user interactions.

My primary areas of interest are : Machine learning, Information retrieval, Online and bandit algorithms, Counterfactual evaluation and learning.

Previously, I was working as a data scientist with the search team at Flipkart Internet Pvt. Limited, India, where I worked on various query understanding and product ranking problems.

Prior to joining Flipkart, I was a MS By Research student at the Search and Information Extraction Lab SIEL, IIIT-Hyderabad under the joint supervision of Dr. Manish Gupta Principal Applied Scientist at Microsoft R&D, India and Prof. Vasudeva Varma, Dean R&D, IIIT-Hyderabad.

To find out more about my work, please visit my CV, Publications, or Google Scholar profile.

If you want to talk about collaborations, research, or just chat, feel free to email me at: 27392shashankgupta@gmail.com or at sgupta2@uva.nl.
