Abinash Bhattachan

(Ph.D. 2013, Environmental Sciences, University of Virginia; M.S. 2008, Environmental Science, Indiana University – Bloomington; B.S. 2006, Watershed and Earth Science, Utah State University)

At UCLA, I will be working with professors Greg Okin and Dennis Lettenmaier on a multi-campus research project examining the links between drought and public health in California. My work will focus on studying the role of climate and soil exposure in Valley Fever incidence.

Ismaila Diallo
(Ph.D. 2015, Atmospheric Sciences, Cheikh Anta Diop University (UCAD); M.Sc. 2009,  Meteorology, Oceanography and Management of Arid Area (MOGMA), Cheikh Anta Diop University (UCAD); B.Sc. 2007, Physics and Chemistry, Cheikh Anta Diop University (UCAD))

Field of research: Climate Dynamics/Climate modelling, hydroclimatology, land-atmosphere interactions, extreme weather events (floods, droughts, heat waves...) and atmospheric teleconnections. The dynamics and impacts of climate variability and change.

Lee Dietterich
(Ph.D. 2016, University of Pennsylvania, B.A. 2010, Harvard University)

Funded by a grant from the US Department of Energy to Prof. Daniela Cusack, I am studying how plant-soil interactions affect ecosystem-level cycles of carbon, nitrogen, and phosphorus in tropical forests.  I aim to improve our ability to predict and mitigate the effects of climate change on these valuable ecosystems and the people who depend on them.

Chunyu Dong
(Ph.D., Hydrology and Climatology, Heidelberg University; M.Sc., Earth System Science, Lanzhou University; B.Sc. Geographic Science, Lanzhou University)

As a team member of an interdisciplinary project, I currently work with Prof. Glen MacDonald, Prof. Gregory Okin and Prof. Thomas Gillespie. This project aims at investigating the impacts and implications of the recent drought for the habitats and energy infrastructure in southern California. My research focuses on capturing the dynamics of the natural vegetation during the drought events in the context of a changing climate. Remote sensing and GIS spatial analysis will be jointly applied to detect the ecosystem response to the disturbance by wildfire and hydrological extremes.

Dongyue Li
(Ph.D. 2016, M.Sc. 2011, Earth Sciences, Ohio State University; B.Sc. 2009, Civil Engineering, Information Engineering University, China)
I work with Prof. Dennis Lettenmaier and also closely work with Prof. Steven Margulis (CEE, UCLA) and Dr. Kostas Andreadis (JPL) on two hydrologic areas: (1) current space-borne hydrologic observations are discontinuous in both space and time due to satellite orbital characteristics. At UCLA, we seek to fill this spatiotemporal gap (specifically for the future SWOT satellite mission) with the combined application of hydrologic modeling and available satellite observations in data assimilation frameworks. (2) With the model and data assimilation systems developed from graduate research, I continue to work on quantifying snow as a water resource, and on characterizing the potential changes of the snow water resource availability over the western U.S. in the context of climate change. 

Ye Liu
(Ph.D. 2015, Atmospheric Sciences, Nanjing University; B.Sc 2010, Atmospheric Sciences, Nanjing University)

I am working on the interactions between vegetation and climate change funded by a NSF project, including the application of a global dynamic vegetation model and its coupling with a global climate model.

Ali Mehran
(Ph.D. 2015, Civil & Environmental Engineering, University of California, Irvine; M.Sc. 2010, Civil & Environmental Engineering, North Carolina State University; M.Sc. 2007, Civil & Environmental Engineering, Iran University of Science and Technology; B.Sc. 2004 Civil & Environmental Engineering, KNT University of Technology, Iran)

My research at UCLA focuses on two different projects. I am working on a NASA project on monitoring and assessing the impacts of atmospheric rivers (ARs) on extreme floods in Northwest United States.  I am also working on a  project on the spatial variability of Wet Tropospheric Delay over the inland water bodies, and estimating NASA’s SWOT (Surface Water Ocean Topography) mission’s error based on Wet Tropospheric Delay.

Ting Yuan
(Ph.D. 2017, Geosensing Systems Engineering and Sciences, University of Houston)

I work with Prof. Yongwei Sheng on NASA-funded SWOT Lake Mapping project. My research focuses on SWOT image simulation, model-based lake mapping method development, data processing and analysis, and lake product assessment.

Bo Zhou

(Ph.D. 2013, Forestry, University of Missouri Columbia; M.A. 2007, Geography, University of Missouri Columbia)

I am currently working on a NASA funded project that involves the University of California, Los Angeles (UCLA), and the U.S. Geological Survey (USGS) and the Bureau of Land Management (BLM) to develop a web-based tool that fuses existing Assessment, Inventory and Monitoring (AIM) data with NASA Earth-observing satellite data to produce spatial and temporal extrapolations of AIM variables.
