About me

I'm a fourth year PhD student in computer science at Brown University. I work in the Brown HCI Lab, advised by Prof. Jeff Huang. My research focuses on understanding, building, and maintaining social support networks over social media. Previously, I worked as a software engineer at constructor.io. I graduated from Brandeis University in 2018, with a degree in Computer Science and Psychology.

Research Projects
