Wartburg College, Waverly, IA   **CURRENT RESEARCH**  I use a combination of empirical and theoretical approaches to address questions within applied weed ecology and classical biological control of weeds. My research focuses on interactions in population and community dynamics, with the goal of increasing the efficacy of weed management and improving health and sustainability of wild and rangeland systems. Current projects include:  evaluating demographic impacts of herbivores and habitat interactions to optimize effective biocontrol of whitetop/hoary cress (*Lepidium draba*L.) and Russian Olive (*Elaeagnus angustifolia*L.);
quantifying the long term outcomes of leafy spurge (*Euphorbia esula*L.) biological control in the northern Great Plains;
improving revegetation and weed management after energy development.  **RESEARCH EXPERIENCE**  Prior to joining the Sidney lab, I was a postdoctoral ecologist with USDA-ARS in Urbana, IL, researching invasion risks and management of perennial crops introduced for biomass production. My graduate work examined plant-insect interactions in native thistles (*Cirsium*sp.) and the ecology of exotic species in forest-opening communities.   /ARSUserFiles/51397/me and thistle.jpg   /ARSUserFiles/51397/dora small.jpg  **PUBLICATIONS:** Gaskin, J.F., **West, N.M.**, Rector, B.G. 2024.
