About Me

I am a fourth-year PhD student in the Department of Engineering at the University of Cambridge and a member of Churchill College, supervised by Dr. Stephan Goetz. My research focuses on Natural Language Processing (NLP), Large Language Models (LLMs), and agentic systems. If you are interested in related topics, please feel free to contact me!

Prior to this, I obtained my master’s degree in the Department of Computer Science and Technology at the University of Cambridge. My thesis focused on language models and federated learning, supervised by Dr. Nicholas Lane. I received my bachelor’s degree in Computer Science with Artificial Intelligence at the University of Nottingham.

Research

My research focuses on agentic systems, reasoning & post-training, and LLM generation and evaluation. I welcome collaborations on these and related topics.
01

Agentic Systems

Studying self-evolving agents and recursive self-improvement, with a focus on agent harness evolution, automated post-training, and multi-agent systems.

02

Reasoning & Post-Training

Improving the reasoning capabilities of language models through chain-of-thought, data synthesis, supervised fine-tuning, and reinforcement learning with verifiable rewards (RLVR).

03

LLM Generation & Evaluation

Developing reliable methods for LLM generation and evaluation, particularly for complex and domain-specific tasks.
