Welcome Message

Welcome to a place where chemistry and biology meet to inspire new molecular discoveries. At the Bag Laboratory, we design and study functional molecules to understand how their structures shape their properties, reactivity, and interactions with biological systems.

Our research brings together synthetic chemistry, chemical biology, molecular recognition, and photophysics. Through thoughtful molecular design and careful experimentation, we explore questions in fundamental science and investigate how molecular insights can lead to new possibilities.

We value curiosity, rigorous research, creative thinking, and collaboration across disciplines. We are also committed to mentoring students and supporting the next generation of researchers as they develop the skills and confidence to pursue their own scientific questions.

Explore our research themes, publications, projects, and laboratory activities to discover the ideas and discoveries taking shape in the Bag Laboratory.
