Introduction of Research

My research mainly focus on the molecular mechanisms of cell polarity establishment and maintenance, which is a basis for differentiation of unicellular and multicellular organisms. The mechanisms of crosstalk between environmental signal (such as light and gravity) and plant development as well as their evolution are also investigated.

Self Introduction

I am fascinated by the beauty and mystique of biological activity. I would like to share these thoughts by working together with you in our lab. I understand that the period in university is important before starting your career. Therefore besides research activities, I would also like to focus on educational activities. If you are interested in in our lab, please let me know. I am very happy to introduce our lab. I am currently looking for people working together in our lab.
