Daniella M. Rempe

Jura_Visit_credit_Jennifer_DruhanDaniella’s long-term research goal is to promote the sustainability of water resources by contributing to a mechanistic understanding of groundwater and vadose-zone processes, particularly in mountainous regions.  Her current research focuses on understanding controls on the spatial pattern of weathering on actively eroding landscapes and the implications of that weathering on moisture storage and transport in fractured rock.

Daniella’s expertise lies in hydrologic field observations, fluid flow and near surface geophysics. She holds a doctorate in Earth and Planetary Science and a Masters of Science in Environmental Engineering, both from the University of California, Berkeley and a Bachelors of Science in Geosystems Engineering and Hydrogeology from the University of Texas at Austin. Daniella’s research experience and outlook are highly interdisciplinary and she actively collaborates with a diverse network of scientists through the NSF Critical Zone Observatory program and the Wyoming Center for Environmental Hydrology and Geophysics.

 Graduate students 

Alison Tune

PhD expected 2021
B.A. Environmental Earth Science, Washington University in St. Louis, 2014

Alison is interested in understanding the biotic influences on water cycling throughout the critical zone.  Her research focuses on the role of microorganisms on dictating water flow pathways in the unsaturated zone. In particular, she is interested in weathering induced by microbial activity within the fractured hillslopes of the Eel Critical Zone Observatory, and how that is represented in chemical and physical observations.

Logan Marcos Schmidt

PhD expected 2022
B.S. Geophysics, University of Texas at Austin, 2017

Logan is interested in the shallow subsurface and its interaction with terrestrial ecosystems. His graduate research seeks to characterize and model the physical and hydraulic properties of the upper <100 meters of the surface using geophysical techniques.

Caroline Hackett

M.S. expected 2018
B.S. Civil and Environmental Engineering, University of Virginia, 2013

Caroline’s research focuses on surface water- groundwater interactions in karst systems.
Co-supervisor: Marcus Gary

Paul Southard

M.S. expected 2019
B.S. Geology, University of Massachusetts Amherst 2016

Paul is interested in how spring-associated vegetation in dryland channels impacts flow dynamics and ultimately channel form and steepness.
Co-supervisor: Joel Johnson

Shawn Lee

M.S. expected 2018
B.A. University of California, Berkeley 2016
Shawn is interested in near surface seismic processing and interpretation with applications to subsurface hydrology and landform processes. Masters research includes numerical analyses of stress and seismic tomography.

Undergraduate students

Nick Soto-Kerans

B.S. Hydrogeology expected 2019

Nick’s research interests are in hydrogeology and geophysics.


Nathan Hsu

B.S. Geosystems Engineering and Hydrogeology expected 2018

Nathan’s research interests are in groundwater surface water interactions, and specifically, the role of the vadose zone in controlling the composition of groundwater.  Nathan’s undergraduate research focuses on the timing of groundwater responses to storms in fractured bedrock groundwater systems.

Yinuo Wang

B.A. Geological Science expected 2018

Geochemistry and hydrogeology

Technical research staff

Brandon Minton

Research technician/magician

Brandon is a graduate of The University of Texas in his home town of Austin. He first received his B.S. in Marine and Freshwater Biology at UT Austin after serving in the U.S. Coast Guard. Early research interests focused on the biodiversity of herbivorous fish populations within reef communities located along the Mesoamerican Barrier Reef System. However, after shifting over to a Geosciences track for his master’s work, Brandon’s interests moved towards exploring and understanding deepwater sedimentation processes. Through a novel set of experiments, Brandon examined the feedback between sediment loading by turbidite deposition and flow of a mobile substrate due to an unequally distributed sediment load that ultimately gives rise to minibasin formation. After completing his M.S. in Geosciences, he now serves as a research engineer for the Rempe Hydrology Group at the University of Texas at Austin.
