per day) for graduates students. These courses include:

·       Statistics (beginner level)

·       R language for statistics

·       Critical scientific reading

·       Nutrient cycling

·       Reproducible science

Teaching assistant: Assisted the main instructor of Statistics (advanced level) at Kunming Institute of Botany, XTBG (June 2021, June 2020, October 2019, October 2018, April 2017).

Research Interests

My current projects continue to examine the biodiversity-nutrient cycling nexus. More specifically, I am interested in further understanding what drives nutrients cycling/release from woody debris to soil and or atmosphere My research ultimately seeks to mechanistically predict the fate of organic matter whether from leaf litter or woody debris. I tempt to revive the need to include unconventional and neglected factors such as bark to understanding of its influence on the decomposition of wood. More importantly, my objective is to extend and test the hypothesis of afterlife effect/legacy and here trying to linking up knowledge we can learn on how does a particular organ C return to soil/atmosphere could be influenced or dictated by another completely unrelated different organ?
