                Career summary

                Since the beginning of my career, I have developed a strong interest in the molecular basis of developmental biology in general and more particularly of plants. After a long period of researching signal transduction in meristems, my research focus shifted to the epigenetic control of plant development and epigenetic plant memory of extrinsic signals including abiotic and biotic stress. Hence, I am a developmental plant biologist by training with more than 20 years of laboratory experience and a strong background in epigenetics, stress responses/memory, signal transduction, gene regulatory networks (GRN) and their roles in plant development including de novo root regeneration (DNRR), stem cell maintenance, flowering time, root, flower and leaf development. Over the years, I was working in a wide spectrum of modern molecular and plant biology. I am an expert in the analysis of plant phenotypes and morphological changes as well as the molecular basis of genetic and epigenetic gene regulation in plants. My team at the Lushan Botanical Garden, Jiangxi Province and Chinese Academy of Science (Nanchang, China), works on 'Plant Epigenetics and Development' of Arabidopsis, Populus and economically significant trees. Our current projects include 'Plant-Memory' and 'Hormonal and Epigenetic Control of De Novo Root Regeneration (DNRR).'
