Hi! I am a PhD student at National University Of Singapore. I am doing my thesis with Prateek Saxena. My current focus is to design differentially private machine learning algorithms, especially on graphs, that enable end applications such as node classification and recommendations. I like building usable private technologies in general. I opine that rigourous user privacy and monetizing users’ data can and should co-exist.

I have experience in program analysis, synthesis, debugging and security of blockchains.


In 2017, I graduated from IIT Kanpur where I was fortunate to work with Indranil Saha. I visited Prateek in 2017 for an internship before joining him as an advisee.


I was fortunate to work with two exciting companies, Flipkart India and Aqilliz. Flipkart India (now owned by Walmart) gave me an opportunity to work on their anomaly detection engine. Aqilliz is an exciting startup from Singapore where I had a chance to demonstrate the impact of applying Differential Privacy protection on the utility of widely-used queries like recommendations.

Other interests

My interests range widely from Computer Science to Psychology, Astronomy, Music, Cricket and Animals. I love singing and relish performing almost anything on a stage(of course after practicing….). I will probably stay in Singapore for at least another three years, so, If you are here then feel free to drop by and say hoi.
