We are delighted to co-host the ETH–UZH–UTokyo Joint Symposium in partnership with KEPLR (Key-Molecule-Network in Plant Reproduction). Organized by the Division of Plant Biology and Chemical Biology at the University of Tokyo and KEPLR, this one-day event will bring together leading researchers from ETH Zurich, the University of Zurich, and our department to showcase cutting-edge advances in plant science, chemical biology, and bioengineering.

KEPLR members Prof. Dr. Jeffrey W. Bode (PI), Prof. Dr. Kentaro K. Shimizu (PI) and Dr. Yuuma Ishikawa (formerly of the Wolf lab) will also present at the symposium.
