A portrait of Lucy Qin smiling in front of a rose bush

lucy qin

I'm a PhD candidate (fourth year) in computer science at Brown University. I work on privacy and applied cryptography in the Encrypted Systems Lab, advised by Seny Kamara. Broadly, my work focuses on designing usable cryptographic solutions to address privacy issues encountered by specific user groups. I am also a Visiting Scholar in the Safety and Society Group, led by Elissa Redmiles, at the Max Planck Institute for Software Systems. My work is supported by the NSF Graduate Research Fellowship.

Previously, I was a researcher and software engineer at the Hariri Institute for Computing where I implemented cryptographic capabilities (such as secure multi-party computation) to support public initiatives. I graduated from Tufts University with a B.S. in computer science and economics.
