About me
AI Engineer & LLM Researcher
Hello! I'm Cecilia Nyberg, an AI Engineer and researcher focused on LLM agents, applied deep learning, and AI systems.
My recent work focuses on tool-using LLMs, including fine-tuning models for multi-step tool use, improving robustness to prompt-structure changes, and building agent systems with reasoning, retrieval, memory, and function calling.
I completed my Master's thesis at Ericsson, where I applied machine learning and time-series forecasting to optimize energy usage in radio units. A manuscript based on this work is currently under minor revision.
I am currently a visiting researcher at the Deep Learning Lab at Seoul National University, where my research focuses on LLM agents, tool learning, and applied AI systems. My current work includes a paper on prompt-robust tool learning for LLM-based ship inspection workflows.
Feel free to explore my projects and experience on this site.
