At UCLA, I am studying coral reef ecology and reef fractional cover classification techniques funded by a NASA Hyperspectral Infrared Imager (HyspIRI) Preparatory grant. I will be combining high-altitude hyperspectral imagery, field surveys, and simulation models to answer questions relating to environmental thresholds of coral bleaching and the effect of water column conditions on accurate benthic classifications.

(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.

(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.

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.

I am part of two projects at the moment. One is NOAA's river hydrodynamics project which is under the supervision of Professor Dennis Lettenmaier. I am conducting research on the thermal impacts of reservoir operations on downstream stream temperatures. This is a project that includes developing a model for management of temperature releases from reservoirs in the Central Valley.
In my second project, I am working under the supervision of Professor Eric Wood from Princeton University in developing a global near real-time drought monitoring system based on observations from NASA's soil moisture Active-Passive (SMAP) satellite.

At UCLA, I am studying supraglacial hydrology of the Greenland Ice Sheet funded by a NASA Cryospheric Project. I am analyzing supraglacial rivers, lakes, moulins, and internally drained catchments on the ice surface and their potential impacts on ice sheet mass balance and sea level rise.

At UCLA, in collaboration with Prof. Glen M. MacDonald, I am studying the distribution patterns of the recent dead and live micro-faunal assemblages in southern California coastal marshes in relation to environmental parameters via multivariate statistical analyses. This innovative ecological data will serve as a modern analogue for paleostudies to reconstruct past marsh variations in salinity and relative elevation over the last 2000 to 6000 years that will add to a comprehensive understanding of the wider climate changes and serve as a key for future modeling.
Field of study: micropaleontology and paleoecology (specializing mainly in benthic foraminifera and ostracods), sedimentology, and Quaternary and Holocene paleoenvironmental reconstruction.

My research broadly uses remote sensing analysis to monitor changes in our environment. At UCLA, I am working with Dennis Lettenmaier to map variations in global surface water resources over time. I am also studying past and future drought conditions in the western U.S. and the implications for fire risk. In addition, I hold a joint research appointment at Columbia University, where I am using satellite observations of fire activity to quantify the influence of tropical fire emissions on regional air quality and public health.

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.
