Hi, I’m Palak! I study the real world implications of the various ways privacy and security are defined and guaranteed today.


I’m a Ph.D. candidate in Theoretical Computer Science at Boston University. My research uses the lenses of cryptography and differential privacy to design privacy-respecting systems and understand the downstream effects of those technologies on the individuals they intend to protect.

Since I primarily address sociotechnical problems, my research endeavours are often interdisciplinary; for example, my colleagues and I have been awarded a grant from the Boston University Center for Anti-Racist Research to study the downstream effects of differential privacy in the census on marginalised communities.

I presented my work that models the security of the Signal Architecture at the Stanford Security Lunch.
Our goal with the composable model for end-to-end secure messaging is not only to provide an idealised security guaranty that enables the analysis of  the Signal protocol but also to enable the analysis of protocols that use Signal (or any protocol that realises our functionality) by defining an ideal module is readily usable as a component within other protocols in security-preserving manner.

Thank you to everyone who attended and engaged with my presentation! It was a great experience.

I passed my qualifying exam!
I’m grateful for all the support and guidance from my qual exam committee members, Adam Smith, Ran Canetti, and Mayank Varia. Also, I’d like to extend a special thanks to all the students and faculty who attended my talk — seeing a room filled with encouraging smiles truly made a difference.

I had the wonderful opportunity to be a mentor at Tech for Change‘s Civic Tech Hackathon .
The student groups had thought-provoking ideas and I thoroughly enjoyed meeting other mentors with similar interests and widely varying expertise!
