  Research Experience

       Associate professor, Forest ecology, Forest Canopy Ecology group, 09/2018-present

Young Scientist (Forest Ecologist), world agroforestry centre, China 07/2016-09/2018.

Conducting field study and assisting project manager for implementation of a

German government funded project on “Green rubber: helping to alleviate poverty and

aiming to restore ecosystem services in rubber plantation upper Mekong region”.

Performed prediction models in R after post micro spectroscopy analyses of soils samples

under an international on land degradation surveillance project.

collaborators on data analysis of role of microbial (fungi DNA sequences) in wood decomposition, 2016 (one week) and 2017 (two weeks).



         Designed and taught several intensive, high level short courses (Monday-Friday, 6 hours

per day) for graduates students. These courses include:

·         Statistics (beginner level)

·         R language for statistics

·         Critical scientific reading

·         Nutrient cycling

Teaching assistant: Assisted the main instructor of Statistics (advanced level) at Kunming Institute of Botany (October 2018, April 2017). Conducted examples and assisted with the course. Helped to engage students in advanced statistics with different teaching methods and feedback to make it
