Theodore Barnhart

Physical Scientist at USGS

I’m interested in how climate change driven changes in snowpack dynamics alter how snowmelt is partitioned between forest water use and streamflow.

I collaborated with the Ecohydrology Lab as a 2015 CUAHSI Pathfinder Fellow. When not working I can be found skiing, mountain biking, rafting, or baking artisan bread.

Ryan Bart

Disturbance Ecohydrologist at UC Merced

I study the impacts of land-cover and climate change on ecohydrologic processes. My most recent project is exploring the connections between land management, wildfire, and ecosystem processes. 

When I am not working, I am usually spending time with my wife and two boys. My interests include building with blocks, reading Captain Underpants and playing Pokémon… OK, actually my boys’ interests, but I get roped into doing them quite frequently. Time for cycling, backpacking and world travel is more elusive.

Gabriella Boisrame

Assistant Research Professor, Environmental Engineer

I study the effect of land cover changes on the water balance in order to better understand how our how managing natural wildfire in landscapes can improve water resources and forest health.

I am a California native and a proud graduate of Whitman College in Walla Walla, Washington. As a math major and avid hiker, I enjoy being able to both quantify my surroundings and enjoy them aesthetically!

Erin Hanan

Assistant Professor of Fire Ecology, UNR

I study interactions among plant, soil, and hydrologic processes in arid systems. Disturbances such as wildfire, insect outbreaks, and forest clearing, play an important role in these dynamics, and in many ecosystems, disturbance events are becoming more frequent and severe in response to climate change and growing human populations. I use process-based models, remote sensing, and empirical analysis to answer questions about how climate change will affect future fire regimes, how these shifts will alter biogeochemical and ecohydrologic processes, and how we can mitigate the effects of climate change through management.

Hui Peng

Associate Professor at Ocean University of China

I am interested in how forestation influences soil moisture and streamflow under the impact of climate change in semi-arid areas. I am also interested in nitrogen transport in soil, groundwater, and streamflow. I like photography and travel when I am not working.

Yun Yang

Post-Doc Researcher at USDA-ARS Hydrology and Remote Sensing Lab

I am interested at evapotranspiration estimation from field to continental scale by fusing satellite data from multiple sensors, for example, GOES, MODIS and Landsat.

During my spare time I like to travel to different places, explore different cultures, and read.
