Chunyu Dong is a postdoctoral researcher at UCLA’s Institute of the Environment and Sustainability and the Department of Geography. He has a research background in the fields of ecohydrology and snow hydrology. Chunyu’s research seeks to understand the impacts of climate change on water cycle and terrestrial ecosystems at various scales. Multiple methods have been applied in his studies, e.g. remote sensing, hydrological modeling, field observations, and hydrogeochemical analysis. He has developed novel algorithms for improving satellite snow data, which can significantly increase accuracy of the remotely sensed snow maps and remove all the cloud pixels. He has also contributed to developing the time-lapse photography as a snow process monitoring technique. Chunyu obtained his Ph.D. in Hydrology and Climatology at the Heidelberg University (2016). He currently works with Prof. Glen MacDonald, Prof. Gregory Okin and Prof. Thomas Gillespie, as a team member of an interdisciplinary project that aims at investigating the impacts and implications of the recent drought for the habitats and energy infrastructure in southern California. His research focuses on investigating the differential vegetation sensitivity to drought across ecological communities, the interactions between wildfire activities, vegetation dynamics, drought, and climate change in California.
