Hi there, I'm Yunsung 👋

AI Research Engineer who bridges research and production

Head of Research, WoRV @ MaumAI · Adjunct Professor @ DGIST

I'm an AI research engineer with strong foundations in both research and practical engineering:

• 🔬 Research background: 10+ publications in top-tier conferences (NeurIPS, CVPR, ICLR, AAAI) with 1.9K+ citations
• 🤖 Embodied AI: Leading research on foundation models that unify language, vision, and action for robotics and autonomous driving
• 💻 Engineering experience: Previously shipped commercial AI products at Wrtn reaching 5M+ MAUs
• 🎓 Teaching: Undergraduate coursework in Physical AI at DGIST, School of Undergraduate Studies
• 🍸 Fun fact: I'm a licensed home bartender in my free time — Korea's national Craftsman Bartender license!

What I'm passionate about

The work I find most interesting happens where a research result meets a running system. My focus right now:

• 🦾 Vision-Language-Action models and robotics foundation models
• 🌏 World models for robotics and autonomous driving
• 🧠 Autonomous agents with memory and personalization
• 🔄 Diffusion models and generative AI
• 🚀 Scaling research prototypes to production-ready systems

Let's connect! ☕
