👨‍💻 About Me

Engineer and business consultant in the energy sector, working at the intersection of industrial decarbonization, clean hydrogen and AI for materials discovery. My background is in electrochemistry (MSc thesis on electrodeposited catalysts for the hydrogen evolution reaction), and I now build ML and agentic tools that speed up R&D for low-carbon technologies, from catalyst screening to closed-loop optimization.

  • ⚡ Specialized in electrochemistry, green hydrogen and catalyst discovery & optimization
  • 🤖 Building local-first agentic AI: RAG, evals, memory, MCP and prompt/context engineering
  • 🎯 Goal-driven generalist who enjoys collaborative teams and creative solutions to hard problems
  • 🌍 Here to contribute to the green transition

🚀 Featured Projects

Project What it does
🧪 catalyst-kg-agent Knowledge-graph-grounded, cost-aware multi-agent system for green hydrogen catalyst screening on Materials Project data. Uses MACE & CGCNN surrogates, Bayesian optimization, pydantic-ai agents and MLflow tracking.
🧠 notion-second-brain Fully local RAG agent over my Notion workspace. Hybrid dense + sparse retrieval, cross-encoder reranking, Qdrant, quantized Ollama models and an eval harness with anchored rubrics.

    I'm excited to share the insights I gained from my favorite lecture in the **Agentic AI** (*CS294-196 Fall 2025*) course ([https://agenticai-learning.org/f25](https://agenticai-learning.org/f25)) by [UC Berkeley’s RDI Center on Decentralization & AI](https://rdi.berkeley.edu/): “AI Agents to Automate Scientific Discoveries” by James Zou.

    ● First, it introduced the concept of using AI agents as “𝗰𝗼-𝘀𝗰𝗶𝗲𝗻𝘁𝗶𝘀𝘁𝘀” to automate and accelerate scientific discoveries. Modern AI agents are able to access specialized tools, databases and memory, enabling them to tackle versatile research problems, such as scientific hypothesis generation, experiment design, data analysis and paper writing.

    ● Illustrating this capability is 𝗧𝗵𝗲 𝗩𝗶𝗿𝘁𝘂𝗮𝗹 𝗟𝗮𝗯, an AI-human collaboration for research. It mirrors a real research lab, with a “principal investigator” agent overseeing specialized sub-agents with different “backgrounds”, while a human researcher provides high-level feedback. These agents are able to hold efficient group meetings with each other based on an agenda provided by the researcher, as well as individual meetings, where the researcher interacts with a single LLM to solve a particular task. Teams of multiple agents debate, leading to more creative and robust reasoning compared to a single agent working alone.
