I am a computer scientist interested in everything networked: from protocols and applications to the hardware that carries our data across the Internet. My goal is to make networks faster, more reliable, more secure, and lately, more fair and equitable.

In our HotNets 2019 paper, Ranysha Ware discussed why ‘harm’ is a better way of thinking about congestion control deployability rather than ‘fairness.’ The latest Systems Approach textbook now includes a discussion of harm in introducing congestion control to students.

This week, Facebook suffered an all-day outage due to errors in their BGP and DNS configuration. I spoke to Charlotte Hu of Popular Science about what went wrong and why increasing centralization of Internet services makes us more prone to such catastrophic failures. Read more here.

Nirav Atre was awarded CMU’s Cylab Presidential Fellowship in support of his work on denial-of-service attacks and algorithmic complexity. Congratulations, Nirav! Read more here.

I enjoyed talking with Shira Ovide of the New York Times about how the Internet’s constant ability to adapt to failures and congestion kept things running (more or less) smoothly during COVID stay-at-home orders. Read her article here.

Kernel bypass approaches to networking provide very high throughput and low latency, at the cost of ease of administration. Operators lose many debugging, management, and scheduling tools that OS kernels typically offer when packets bypass the kernel altogether. At HotOSXVIII today, Hugo Sadok suggests that we might be able to keep both manageability and high performance by implementing an OS interposition layer on FPGA-based SmartNICs. Read the paper and watch the talk to learn more.

Common Requests

  • Prospective Undergradute Interns: I accept students through the ISR REUSE Program. Read more about how to apply here.
  • Prospective PhD Students: I can advise students in any SCS department and in ECE. Apply to whichever program fits you better (or both). I am not on the admissions committee for any PhD program.
  • Peer Review: I only review for conferences which (a) have an enforced anti-harrasment policy, (b) use double-blind review, and (c) offer open-access proceedings.

Research Talks


Justine Sherry is an assistant professor at Carnegie Mellon University. Her interests are in software and hardware networked systems; her work includes middleboxes, FPGA packet processing, measurement, cloud computing, and congestion control. Dr. Sherry received her PhD (2016) and MS (2012) from UC Berkeley, and her BS and BA (2010) from the University of Washington. Her research has been awarded the vmWare Systems Research Award, the Applied Networking Research Prize, the SIGCOMM doctoral dissertation award, the David J. Sakrison prize, and paper awards at USENIX NSDI and ACM SIGCOMM. She is a member of the DARPA ISAT Study Group and the SIGCOMM CARES Committee. Most importantly, she is always on the lookout for a great cappuccino.
