BIOS
Dr Juang received his Ph.D. degree from Nicholas School of the Environment and Earth Sciences at Duke University. His research speciality focuses on interactions between surface and atmosphere, hydrometeorology, impacts of land use changes on micrometeorology and hydrological cycle, and environmental monitoring and analysis.
The more specific topics of Dr Juang’s research can be classified into two different categories:
- Quantifying the fluxes passing through the interface of the terrestrial biosphere or different vegetation types (forest, wetlands, agricultural fields, etc.) and the near surface atmospheric boundary-layer. In addition, his research also focuses on characterizing how these ecosystems or vegetations respond to the changes in the environment over different temporal and spatial scales.
- Exploring how the changes in land use and land cover alter the microenvironment. Examining the impact of the built environment on the regional microclimate and the influences on thermal comfortability and thermal stress of the human body. Analyzing the role of land cover changes on the regional convective rainfall events.
In addition to research, Dr Juang devotes himself to academic activities. He served as the chief editor for the TSSCI (Taiwan Social Science Citation Index) journal “Journal of Geographical Science” from 2018 to 2021, and served in several domestic academic associations in the past years.
Furthermore, Dr Juang actively contributes to the international academic society. Due to his expertise on biosphere-atmosphere interactions and flux measurement, starting from the year of 2021, Dr Juang has been invited as a member of the Science Steering Committee (SSC) in the international academic organization AsiaFlux.
Research interests: surface-atmosphere interactions, microclimatology, observation and analysis on micrometeorology in built environment, analysis of thermal environment for human body
