Shaddi Hasan
I am an assistant professor of computer science at Virginia Tech. My research interests are in networks, information and communication technologies for development (ICTD), HCI, and distributed systems.
My research aims to build network infrastructure that meets the needs of the humans that rely upon it -- users, network operators, and policymakers. My research group builds operational, deployable systems informed by qualitative research with users and network operators and evaluated through real-world deployments and fieldwork. In doing so, our work expands the frontiers of the Internet beyond what is achievable today, providing more equitable access to communications, especially in rural and developing regions. My research has appeared in venues such as ICTD, SIGCOMM, IMC, and NSDI, and paper awards at NSDI, ACM DEV, and IEEE DySPAN.
I am actively recruiting motivated PhD and MS students with interests in networking, HCI, and policy. In addition, I have opportunities for motivated Virginia Tech undergraduates interested in research.
- Prospective MS and PhD students: Please apply to the Virginia Tech CS program through the normal channels, and mention my name in your application.
- Current Virginia Tech undergraduates: Please send me email describing your research interests along with your CV/resume.
Prior to Virginia Tech, I completed my PhD (2019) at UC Berkeley, advised by Eric Brewer, and my BS (2010) from the University of North Carolina at Chapel Hill, where I worked with Kevin Jeffay and Jay Aikat. In 2014, I co-founded Endaga (press), which was acquired by Facebook in 2015; I worked with Facebook Connectivity until 2021, where I helped start the Magma project.
I am lucky to work with a number of excellent students as part of the Systems, People, Infrastructure, and Networks (SPIN) Lab.
- Demetrius Davis (PhD)
- Wesley Woo (PhD)
- Tauhid Nabi (PhD)
- Zhuowei Wen (MS)
- Jamous Bitrick (MS)
Our group alumni:
- Zahra Yazdani (BS 2023; next PhD student Georgia Tech )
- Molly Hickman (MS 2022; next nLine)
Here's my CV.
