About

I’m a physicist with a PhD from the University of Cambridge, with a background that bridges science, data, and technology. I’ve worked on everything from NASA research and astrophysics to bioengineering and AI training for cutting-edge models. Lately, I’ve been focused on evaluating and fine-tuning models, particularly in high-stakes areas like healthcare, aerospace, and LLM safety. My toolkit includes Python, SQL, C++, MATLAB, PyTorch, and Hugging Face, and can build simulations, data pipelines, and scientific models. As a Gates Cambridge Fellow, I’ve led research teams, published extensively, and contributed to mission-critical modeling work. I’m currently open to new opportunities where physics, AI, and impact meet—whether that’s: * AI/ML roles in healthtech, space, or scientific R&D * LLM evaluation or fine-tuning for technical domains * Any role where thoughtful modeling can move the needle Based in Los Angeles and open to remote, hybrid, or global work. Always happy to connect.
