Catchment Hydrology Technical Committee Members

Technical Committee Chair

Dr. Matthias Sprenger
he/him/his

​Research Scientist; 
​Lawrence Berkeley National Laboratory ​

I investigate hydrological processes in the Critical Zone using stable isotopes of water in field measurements and hydrological and machine learning modelling on scales ranging from soil profiles to catchments.

Technical Committee
​Chair-elect

Dr. Christa Kelleher
she/her/hers

Assistant Professor; Lafayette College

My research seeks to understand the sensitivity of hydrological systems to change at reach, watershed, and regional scales. In particular, I examine how humans are agents of change in the hydrologic cycle. This includes exploring how human activity alters pathways of water through landscapes, and how land development and stream restoration may alter water quality and local hydrology.​

​Technical Committee Chair

Dr. Genevieve Ali
she/her/hers

My work focuses on runoff generation processes, contaminant export, material connectivity and watershed classification through the integration of field work, laboratory work, and modelling. My research group examines not only forested watersheds but also human-dominated watersheds (e.g., agricultural, periurban), and our work spans small headwater catchments to large transboundary basin scales.

Amanda Donaldson
she/her/hers

PhD Candidate; University of California, Santa Cruz

I am interested in how vegetation shape watershed form and functions such as erosion, subsurface weathering, groundwater recharge, and streamflow.

Dr. Kevin McGuire
he/him/his

Professor; Virginia Tech

My research in catchment hydrology emphasizes streamflow generation processes, forest ecosystems, and water-soil-biogeochemical interactions.

Dr. Christian D. Guzman
he/him/his

Assistant Professor; University of Massachusetts Amherst

Hillslope hydrology, sediment transport, nutrient transport, stable water isotopes.

Dr. Nitin Singh
he/him/his

Research Associate; University of Waterloo

I study how anthropogenic alterations and climate influence water availability and nutrient transport from watershed to continental scales. Further, how can we use nature-based solutions to mitigate the impact of global change on our watersheds and society as a whole. My work has implications for water sustainability, management of watersheds, and food-water-climate nexus.

Dr. Sarah Godsey

Associate professor; Idaho State University

Rain-snow transition, intermittent streams, concentration-discharge relationships, diel cycling, emerging contaminants, permafrost hydrology.

Dr. Thom Bogaard
he/him/his (Thom)

Associate professor; Department Water Management, Delft University of Technology, The Netherlands

Hydrology; Geomorphology; Landslide Water management; Nature-Based Solutions Monitoring techniques in water management Natural hazard and risk management Capacity building.

Dr. Holly Barnard
she/they 

Professor; University of Colorado - Boulder

I investigate how forest processes affect water flow dynamics and pathways in soil and streams, and conversely, how water flow paths affect ecological function in mountainous areas. This bridging of hydrology and ecosystem science is key to developing sustainable management of water resources. All of my research involves a combination of field experimentation, field observations and laboratory analysis, and is fundamentally interdisciplinary and collaborative.

Dr. Antonio Alves Meira Neto

Assistant Professor; Colorado State University

I'm interested in advancing hydrologic theory at the catchment scale through comparative analysis and modelling. On a more experimental side, at smaller scales, I like investigating hydrologic processes in natural environments using geophysical methods.

Dr. Adam Price
he/him/his

Research Hydrologist; USDA Forest Service, Pacific Northwest Research Station

Adam is an early-career research hydrologist at the USDA Forest Service, Pacific Northwest Research Station. Adam’s research focuses on non-perennial rivers and streams, watershed scale restoration, and co-production of actionable science to adapt to changing climate.

Dr. Catalina Segura
she/her

Associate Professor, Oregon State University

​My research focuses on understanding how water and sediment move in watersheds and the impact of these processes on water availability, quality, and ecological health. As such my research program is multi-disciplinary. My primary focus is hydrology and geomorphology, often at the intersection of these broad disciplines and ecology.

Dr. Jamie Shanley

Research Hydrologist, U.S. Geological Survey, Vermont

My research applies hydrological and biogeochemical principles to understand how water and solutes move and transform through the landscape from precipitation to streamflow.

Dr. Anna Bergstrom
she/her

Assistant Professor, Boise State University

I focus on watershed hydrology and biogeochemistry in rapidly changing landscapes. This ranges from working at the interface between glaciers their landscapes to exploring changes occurring in our own backyard in Southwest Idaho.

Dr. Theresa Blume

Influence of geomorphology, geology, vegetation, subsurface structures and preferential flow on hydrological response and water storage. Use of tracers for the investigation of hydrological processes: stable isotopes, dye tracers, geogenic tracers, temperature. Investigation of groundwater-surface water interactions with various methods, e.g. high spatial resolution fibre optic temperature sensing.
Dr. Aliva Nanda

CIRES, University of Colorado/ NIDIS, National Oceanic and Atmospheric Administration
​
Elise is the Program Coordinator for the National Coordinated Soil Moisture Monitoring Network (NCSMMN). She works to facilitate learning, distribution of information, and development of tools and resources for the soil moisture community. She is interested in cross-systems thinking, particularly the consideration of how soil moisture data can be better integrated into catchment-wide, interdisciplinary work.

I am interested in understanding the two-way interactions between vegetation and hydrology and how they might influence ecosystem function and resource sustainability in the context of novel environments.

Dr. Alexis Navarre-Sitchler 
She/her/hers 

Professor and Department Head of Geology and Geological Engineering; Colorado School of Mines
Joint Faculty Appointee; Los Alamos National Laboratory

My research focuses on the complex coupling of geochemical processes and fluid flow in systems ranging from long-term weathering in the critical zone, landscape response to wildfire, and subsurface energy systems.  I combine laboratory experimentation, field observation, and advanced numerical simulation to quantify the distribution and temporal evolution of mineral-fluid reaction rates in porous and fractured rocks.
