Molecular mechanisms of development, environmental responses and evolution in plants. We aim to unlock the secrets of plant cells and to understand how plants control their growth, differentiation and environmental responses.

Introduction of Research
Plants exist in an amazing variety of shapes and sizes and act as primary producers to support a multitude of life forms, including us humans. Our understanding of plants, however, remains far from complete. How are plants born and how do they take shape? How do they respond to environmental changes? Unlike animals, plants lack the ability to move on their own and have therefore evolved unique responses and developmental mechanisms. We want to understand these unique aspects of plant biology from the molecular and cell levels to the individual level and to find a way to help plants and humans to coexist. Here are main topics in our lab. 1. Investigate control mechanisms of plant proliferation, differentiation, regeneration and totipotency. 2. Examine the crosstalk between environmental responses and developmental programs – aiming to develop plants that grow well in extreme environments. 3. Explore the mechanism of multicellularity. 4. Unravel the evolutionarily diverse mechanisms of plant morphology.
