What’s New?
- Immense gratitude to Prof. Zakir Durumeric and Gerry Wan for hosting my talk at Stanford University! The visit was incredibly welcoming and intellectually enriching.
- Glad to be invited as a TPC member of IMC 2024!
- Honored to have been invited by Prof. Taejoong (Tijay) Chung for a research talk at Virginia Tech, it feels like a special homecoming to a place where I’ve spent a few years collaborating with brilliant mentors.
- Our recent work on the highly efficient ML-based traffic analysis system ServeFlow: A Fast-Slow Model Architecture for Network Traffic Analysis is now on arXiv! So are CATO and AC-DC.
- Recently, I had the privilege of giving a talk on “Operational ML in Networking” at both Carnegie Mellon University and Emerald Inc., extending my sincere thanks to Prof. Peter Steenkiste and Prof. Srinivasan Seshan at CMU, and Prof. Dina Katabi at MIT for their gracious invitations.
- How to generate high-fidelity PCAP traces using a Generative Model? Our latest work “Generative, High-Fidelity Network Traces” explores this question and has just been accepted by HotNets’23. Our full paper NetDiffusion: Network Data Augmentation Through Protocol-Constrained Traffic Generation has been accepted by SIGMETRICS’24. Huge thanks to Chase, Aaron, Arjun, Paul, Francesco, and Nick for making it happen!
- Started to serve as the Head of the Student Advisory Council at the ACTION AI Institute.
- Our paper “LEAF: Navigating Concept Drift in Cellular Networks” has been accepted by CoNext’23! It is the first end-to-end work to characterize, explain, and mitigate concept drift in networking. Huge shout out to Francesco, Paul, Arjun, Nick, and our Verizon collaborators Hector, Tim, and Brian!!
- We got our paper “AMIR: Active Multimodal Interaction Recognition from Video and Network Traffic in Connected Environment” accepted at UbiComp/IMWUT 2023. Shout out to Tarun, Ted, Jinjin, John, Sanjay, and Nick! Check out our website for released datasets, processed features, models, and analysis pipelines.
- Thanks to the invitation from Prof. Wenke Lee, I shared my research “Towards Data-centric AI for Robust and Secure Operations in Networks” at GaTech. Really glad to have the opportunity to talk to the great minds at GaTech!
