Dr. Sarah Null

Aquatic Habitat, Climate, and Water Analysis (ACWA) Lab

People

Sarah Null

Associate Professor, Watershed Sciences, USU

Research Faculty, Ecology Center, USU

Sarah’s expertise is in water resources systems modeling, physical geography, monitoring rivers and aquatic habitats to support modeling, and understanding climate change effects and potential adaptations on water systems. Improving environmental objectives in systems models and validating models with innovative field monitoring leads to improved decision-making for water systems and river restoration for sustainable water management in an uncertain future.

Specialties: Water resources systems analysis and management; human and aquatic ecosystem tradeoffs, hydroclimate change

Sarah received her bachelor's degree in international economics at UCLA, master’s degree in physical geography from UC Davis. Her PhD was funded by an EPA STAR fellowship and is in physical geography from UC Davis. Prior to coming to USU, she worked as a scientist at Watercourse Engineering, Inc. and as a postdoctoral scholar at UC Davis' Center for Watershed Sciences.

Post-Doctoral Scholars

Sapana Lohani

Postdoctoral Researcher (co-advised with Peter Weisberg)

Sapana is quantifying the effects of streamflow alteration and tropical deforestation using remotely-sensed data, and is evaluating ecosystem services tradeoffs between aquatic/riparian habitats and hydropower production in the Lower Mekong Basin.

Michaela Teich

Postdoctoral Researcher (co-advised with Jim Lutz)

Michaela is studying the evolution of seasonal snowpacks in different forest ecosystems, including forests that have been recently disturbed by bark beetles and fire, and linking them to snowmelt and water supply.

Doctoral Students

Liana Prudencio

Ph.D. Student - Watershed Sciences

Liana started her doctorate degree in January 2016. She is modeling the effects of stormwater management on water supply and water quality in Utah's Salt Lake Valley. Liana's background is in journalism and sociology.

Researchers

Maggi Kraft

Maggi is developing rainfall-runoff and water management models to understand how snowpack variability from forest disturbance affects runoff and water supply in the American West

Master's Students

Thomas Balkcom

M.S. Student - Watershed Sciences (co-advised with Jiming Jin)

Thomas's research uses field data and computer simulation to predict arctic lake temperature change and aquatic ecosystem response to climate warming. He began his research in August 2016. Study sites are near Alaska's Toolik Field Station.

Johnathan (J.) Neenan

M.S. Student - Watershed Sciences

J.'s research includes field data collection and hydrologic / water quality modeling to highlight river restoration alternatives that best enhance water quantity and quality. He is monitoring and modeling Utah rivers. He began his degree in July 2016.

Dave Betts

M.S. Student - Watershed Sciences

Dave joined the ACWA Lab in August 2013. His research focuses on monitoring, modeling and quantifying ecosystem services in coupled human-natural western water systems. Dave's background is in biology and conservation biology.
