Ecosystem: We study the forest and freshwater ecosystems upon which society depends
Dynamics: We model how ecosystems change over time in response to land-use, climate change, atmospheric deposition, and management. We measure carbon, water, and energy exchange between ecosystems and the atmosphere using eddy-covariance and biometeorology sensors.
Forecasting: We predict the future of ecosystems by combining observations and ecosystem models using statistical techniques.
Lead PI of an NSF sponsored 5-year project that is leading workshops, conferences, and collaborative software development to address the following objectives:

The Ecosystem Dynamics and Forecasting Lab led by Dr. Quinn Thomas at Virginia Tech has funding for a new Ph.D. student position to start January 2021 or August 2021. We are recruiting a Ph.D. student to apply innovative new techniques to combine lake ecosystem modeling with sensor data analyses to forecast future water quality in drinking water reservoirs. The Ph.D. student will help develop forecasts to inform drinking water management using state-of-the-art cyberinfrastructure and communicate their forecasts to water utility managers.
This position will be supported by two NSF projects (smartreservoir.org and flare-forecast.org) that are developing a water quality forecasting system for drinking water supply reservoirs, National Ecological Observatory Network (NEON) lakes, and Global Lakes Ecological Observatory Network (GLEON) lakes. This highly interdisciplinary Ph.D. project will combine high-frequency sensor monitoring, modeling, ecosystem forecasting, and data-intensive analytical approaches from ecology, computer science, and social science. There will be opportunities for both computational and field-based research.
We seek a conscientious and energetic student with quantitative and computing skills who can work independently in a collaborative environment. The student will work closely with the Carey Lab at Virginia Tech (carey.biol.vt.edu) and the Advanced Computing and Information Systems Laboratory at the University of Florida on the project (www.acis.ufl.edu). Students are also encouraged to apply to be a fellow in Virginia Tech’s Interfaces of Global Change graduate program (globalchange.vt.edu) and interact with other students in the Virginia Water Research Center (vwrrc.vt.edu) that is housed within our department. Virginia Tech, as Virginia’s leading research and land grant institution, has a strong interdisciplinary focus on the environment and natural sciences and is located in scenic southwestern Virginia.
The student position will be funded on a combination of research and teaching assistantships, which include a competitive stipend, tuition waiver, and full health insurance benefits. Interested students should send an email letter of inquiry containing an overview of your research interests, your C.V., an unofficial transcript(s), and a list of past research experiences to email@example.com. Please feel free to contact me with questions about the application process, graduate school at Virginia Tech, or potential research ideas.
