aidd / molecular docking / molecular generative models

I am a Ph.D. Candidate in KAIST Chemistry working on AI-driven drug discovery. My recent work focuses on co-folding, molecular docking, and molecular generative models, with an emphasis on reliable structure and interaction modeling.

This site collects research notes, technical posts, and project logs. Outside my core research, I am also increasingly interested in AI agent-driven automation and productivity workflows.

Research

My research focuses on developing computational frameworks for understanding and predicting molecular interactions. Building on PIGNet, a physics-informed graph neural network for binding affinity estimation, I have worked on structure and binding affinity prediction for diverse biomolecular complexes. I am currently developing next-generation foundation models for biomolecular complex structure prediction.

In parallel, I am interested in molecular generative models for lead optimization and de novo drug design, and more recently in phenotypic drug discovery using virtual cells, where my previous work can be effectively leveraged.
