I am a fourth year PhD student at Brown CS where I work on problems in the area of Cryptography and Applied Cryptography with Seny Kamara and Tarik Moataz. I am a member of the Encrypted Systems Lab and CAPS group at Brown. Recently, my research has been particularly focused on Encrypted Search and Structured Encryption where I work on designing and implementing provably secure, efficient and usable schemes with well defined leakage profiles, that also guarantee various desirable security properties of Searchable Symmetric Encryption schemes such as Forward Privacy, Snapshot Security etc. Currently, I am working on new efficient designs for Structured Encryption schemes and private data structures.

Before coming to Brown, I was an undergrad at Lahore University of Management Sciences (LUMS) and was advised by Fareed Zaffar. In LUMS, I worked on projects in different areas of Computer Science such as Privacy, Networks and Graphics etc.

Other Interests / Random Things

I love to travel. I have been to a few different countries and a lot of cities in the United States. For me, the best thing about travel is that I get to sample and relish in the local cuisine.

One of the notable trips I took was my trip to Japan. Majority of my time was spent in Tokyo, Kyoto and Osaka. I did take day trips to Yokohama and Nara. I miss the food I had there everyday.

I love New York!

Lahore is the best city ever though! Well, you can say I am a little biased.

I served as the Chair of Technology on the Brown Graduate Student Council from 2016 to 2018. I also served on the GSC International Committee led by the Chair of International Advocacy.
