About me

I’m Felix Yu. I was born and raised in Hong Kong, and have always been curious about how things work—how the natural world comes about, how intelligence arises within it, and how we come to understand ourselves and the world around us.

I studied applied mathematics at Columbia and completed my master’s at Stanford before returning to Hong Kong to pursue entrepreneurship. For the past decade, I have been building a fintech company that makes software for stock investors. My recent work brings agentic AI and agent harness design into investment research.

Alongside that work, I spend much of my time thinking about intelligence. I want to understand how human intelligence arises and whether machines can develop comparable general abilities. Building learning systems is one way to investigate those questions. That interest has led to more than a decade of AI projects, particularly in reinforcement learning and computer vision, and to becoming a Kaggle Competitions Master. Lately, I have been drawn to LLM reasoning and the systems that enable agents to act and learn.

My curiosity also takes me into physics and philosophy. I am especially interested in complexity, emergence, and the foundations of quantum mechanics: how familiar laws arise from underlying dynamics, and what the wavefunction says about physical reality and our knowledge of it. I pursue these questions as an independent researcher; my research manifesto sets out the direction of that work.

This site collects my projects, research ideas, and shorter writings across subjects. I hope it helps people with similar interests find one another. If something here connects with your own thinking, or you would like to collaborate on research, an AI project, or a competition, please write to me. I would be glad to exchange ideas.

Amor Dei intellectualis is Spinoza’s phrase for the intellectual love of God. I keep it here as a reminder that the search for understanding can be a source of joy.
