Research, Service, Teaching & Advising


Our research goal is to develop software tools for the restoration of natural resources and delivery of ecosystem services, in order to improve human wellbeing and biodiversity. We lead development of the i-Tree tools research suite.  

We address questions involving how trees and landforms within the natural and developed environment: 1) interact with water, energy, and biogeochemical cycles, 2) improve sustainability and reduce pollution, 3) assist in mitigation of, and adaptation to, climate disruption, 4) are represented in land use planning software to increase community engagement, and 5) can bring about a just and equitable world.

The tasks involved in our work include multidisciplinary collaboration, literature and data synthesis, conceptual model building, algorithm and software development, and software dissemination. Issues that we model include river basin restoration, nature-based stormwater management, urban heat island mitigation, river thermal cooling, and building energy conservation.

Teaching & Advising

Office hours can be arranged by email during this period, te at

River Form and Process (ERE 412, ERE612), Fall semester. Two hours of lecture and three hours of lab per week. Theories of river classification are presented and tested using field gathered data. Classified river form and suggested evolution sequences are used to discuss governing fluvial processes. Computational river hydraulics is used to estimate sediment transport, and a design sequence is employed to consider issues of channel stability and restoration.

i-Tree Tools and Applications (ESF 496), Fall semester. Three hours of lecture per week. Use i-Tree tools to complete an urban forest inventory, an assessment of associated ecosystem services, and designs for improved sustainability. Ecosystem services relate to air quality (PM2.5, O3, CO, NO2, SO2), CO2 sequestration, urban heat island mitigation, stormwater avoided, and building energy use. Forest data are obtained from field visits and remotely sensed or archived products.

Engineering Hydrology and Hydraulics (ERE 340, ERE 540), Spring semester. Three hours of lecture and lab per week. Covers watershed hydrology and analysis of rainfall, evapotranspiration, infiltration, and runoff processes as well as hydraulic processes involved with pipe networks, open-channels with flow controls, and groundwater systems.

Hydrology and Biogeochemistry Seminar (ESF 497, ERE 797), Spring semester. Sponsored by Council on Hydrologic Systems Science. Past Talks
