Current Research Interests

  • Mechanism of protein ubiquitination regulating plant biological clock

  • Regulation of plant biological clocks and their growth and flowering by temperature and photoperiod

  • Regulation of protein ubiquitination under high temperature stress in plants

Laboratory Research

The circadian clock is an approximately 24-hour endogenous timekeeper to help organisms respond properly to the rhythmic environmental changes due to the Earth rotation. In plant, circadian clock not only times daily rhythmic physiological processes (photosynthesis, carbohydrate metabolism, biosynthesis of phytohormone and secondary metabolites etc.) but also measures seasonal time to allocate energy for growth, development and dormancy. In addition, it helps plants to anticipate external biotic and abiotic stimuli for stress resilience and their survival. Some knowledge gained from circadian clock studies have been translated to agriculture practices to control flowering time, boost crop yield, and enhance stress resistances and herbicide effectiveness. However, circadian clock-regulated biological processes and their mechanism remain to be explored. My research will focus on the following directions to study the mechanism underlying plant circadian clock and its downstream biological pathways in hope of translating to agriculture.
1.    Understanding how do rhythmic light and temperature signals entrain and maintain plant circadian clock
2.    Deciphering how does plant circadian clock modulate abiotic stress
3.    Investigating how does plant circadian clock regulate seasonal growth and development
The positions are available for undergraduate interns, graduate students and postdocs. If you are interested in studying circadian clock or abiotic stress, welcome to join us!!
