Research: My research program focuses on the dynamics and management of annual weeds in organic farming systems. Current research projects include evaluation and comparison of seed-, seedling-, and mulch-based management strategies in organic vegetables. We also continue to evaluate physical weed control, aiming to improve understanding of the sources of variability in cultivation-based seedling mortality. In a collaborative project with colleagues at the University of New Hampshire and University of Vermont, we are characterizing weed communities across northern New England to better understand likely responses to changing climate. Lastly, a new series of field experiments, motivated by questions from Maine farmers, is studying soil solarization as a weed management practice.
