People use LLM agents to interact with (access/modify) their system and external services. We (@bimalrajgyawali, @samkumar_cs, and Sai) think this can be a bit dangerous 💣⏲️💥 so we wrote a paper (arxiv.org/pdf/2506.13028) on system guardrails for such agent-driven interactions!
Excited to share that our paper, “High-Level Programming for Application Networks,” has been accepted to #NSDI '25! This marks the first step in realizing our vision for Application Defined Networks (ADN).
More details in the thread!
I'm on a plane, and my flight is delayed for over 2 hours. Why? First, they had to replace a seat belt. But their computer didn't recognize the new part number, so they have to replace the entire seat before the plane is allowed to move. The computer made things less efficient...
It’s an honor to have been recognized as a Runner-Up for the @TheOfficialACM SIGSAC Doctoral Dissertation Award at CCS 2024 (@acm_ccs)!
I’d like to thank my nominator and letter writers for this award, and my advisors, mentors, and collaborators during my PhD.
This was a fun project! Developing the reading list as senior grad students, we got to re-read classic systems papers with a fresh perspective. And I'm glad that junior grad students at @Berkeley_EECS now have a more up-to-date reading list introducing them to systems research.

I've wrapped up my postdoc and just moved down to Los Angeles. I'm super excited to start at UCLA CS (@CS_UCLA)! Today is my first day working in person at the @UCLA campus.
In the meantime, I am joining the Allen School at the University of Washington (@uwcse) as a postdoc in the FOCI Center, supervised by Arvind Krishnamurthy (@arvind_uw) and Ratul Mahajan (@ratulm)!
Our paper on Skyplane has been accepted to NSDI 2023! We show how to use network overlays to optimize inter-region bulk data transfer in the cloud.
Our paper is now available on arXiv: arxiv.org/abs/2210.07259
Our research artifact, Skyplane, is open source (see below).

LIVE: The IRTF Open session at 19:00-21:00 UTC on 25 July 2022 during #IETF114 will be streamed live, with #ANRP talks by Tushar Swamy on “Taurus: A Data Plane Architecture for Per-Packet ML” & Sam Kumar on “Performant TCP for Low-Power Wireless Networks” ietf.org/live/ietf114-i…
#ICYMI: “How can we design systems to use cryptography efficiently and manage overheads?” @samkumar_cs Kumar unpacked how to rethink cryptography in the overall system in our interactive #TechTalk.
Thank you, Sam, for this thought-provoking session & @gnychis for moderating it.
