Accepted Paper at LLM4Code 26! Our work on zero-shot software vulnerability classification using LLMs has been accepted at LLM4Code 2026 workshop (co-located with ICSE)! In the paper, we explore a RAG-based pipeline that automatically maps detected vulnerabilities to CWE categories, without any task-specific training and while still performing on par with specialized approaches. Led by our KTH master's student Edvin Nordqvist, this paper marks a nice closing chapter for our SEMLA project! 😄

Accepted Paper at NSDI 26! What if where you store a packet payload could drastically reduce energy use? Our work, Queue-Mem, accepted at USENIX NSDI 2026, reveals that smart payload placement is the key to revolutionizing energy efficiency in terabit-scale NF systems. By cleverly leveraging switch buffer queues, we build the first energy-efficient, high-speed packet pipeline, achieving per-flow processing at Tbps rates using just one commodity server and an ASIC switch.

Three papers accepted at LLM4Code 25! I am super glad to announce that three papers have been accepted in the LLM4Code 2025 workshop (co-located with ICSE)! In the first paper, we explore the possibilities of Transformer-based models in predicting code vulnerabilities from GitHub issues (work led by our former master's student Daniele Cipollone). In the second paper, we are the first to apply domain-specific LLMs pruning, enabling the extraction of efficient sub-models tailored for specific tasks and programming languages (work led by our former master's student Laura Puccioni). Finally, our third paper presents a forward-looking vision on utilizing LLMs to automatically generate formally verified code, paving the way for safer and more reliable software development (work led by Changjie Wang).

New Position! 🚀 Starting today, I am thrilled to join the Connected Intelligence Unit at RISE as a Senior Researcher! My last two years as a postdoc in the NSLab group at KTH have been invaluable in shaping my growth as a researcher. I am deeply grateful to everyone in the group for their support, encouragement, and the many thought-provoking discussions along the way. I look forward to bringing this valuable experience into my new role and applying it to create meaningful impact. Thank you to everyone who has been part of this journey!
