I am an incoming M.S. student in Electrical and Computer Engineering at Carnegie Mellon University. I received my undergraduate degree from the University of Liverpool.

My research interests center on agentic reinforcement learning, self-evolving agents, LLM post-training, and time series forecasting. I am actively looking for internship opportunities. Feel free to reach out if you think I am a good fit!

๐ŸŒป Research Interests

  • Agentic reinforcement learning for long-horizon tasks
  • Self-evolving agents and multi-agent reasoning frameworks
  • Coding agents, especially terminal-based agents
  • LLM post-training for reasoning, alignment, and reliability
  • Time series forecasting with efficient frequency-aware models
