Current Research
I study genetic and physiological mechanisms regulating biomass production of short rotation woody crops (e.g., poplars and willows) grown for phytotechnologies, bioenergy, and fiber.
The provision of ecosystem services associated with these end uses is tightly linked with increasing human population levels at regional, national, and global scales, resulting in the need for such services along the urban to rural continuum that balance community well-being with ecological health and stability. To address this need, I am advancing short rotation woody crop production systems for pollution remediation and renewable energy.
I am developing phytoremediation and other phytotechnologies for ecosystem recovery, remediation, and restoration along the urban to rural continuum

In addition to short rotation woody crops, I also study the impacts of changing climates on patterns of tree adaptation in northern coniferous forest ecosystems.
There is a need for long-term conifer management strategies that optimize ecosystem services such as carbon sequestration and feedstock production potential of plantations and natural forests. The success of such systems depends upon understanding the linkages among energy, climate, and tree genetics, which are vital for promoting biologically and economically sustainable reforestation, afforestation, and gene conservation.
I am evaluating the resiliency and adaptation potential of northern forest conifers to changing climates, specifically as they relate to growth and yield

Why This Research is Important
Understanding the underlying genetic and physiological mechanisms regulating growth and development of short rotation woody crops supports effective deployment of favorable genotypes that helps: 1) reduce impacts from invasive species, 2) provide energy sources that do not contribute to increased atmospheric carbon dioxide (CO2) and global climate change, and 3) improve ecosystems along the urban to rural continuum through recovery, remediation, and restoration. Overall, the knowledge gained from my research helps growers and researchers increase the success of sustainable woody crop production systems, while providing essential ecosystem services such as clean water and healthy soils.

Short rotation woody crops (SRWC) such as Populus species and hybrids (i.e., poplars) are renewable energy feedstocks that can potentially be used to offset electricity generation and natural gas use in many temperate regions, such as Wisconsin and Minnesota, USA. Highly productive poplars grown primarily on marginal agricultural sites are an important component of our future Midwest energy portfolio. Additionally, poplars can be strategically placed in the landscape to conserve soil and water, recycle nutrients, and sequester carbon. These purpose-grown trees are vital to reducing our dependence on non-renewable and foreign sources of energy used for heat and power. Establishing poplar genotypes that are adapted to local environmental conditions substantially increases establishment success and productivity. But, it is difficult to predict field trial success in landscapes where the crop has not been previously deployed.
