Program Goal and Research Focus

The overarching goal of my research program is to study and gain a better understanding of the impact of biotic and edaphic factors on growth, population and community dynamics of agrestal, ruderal,

Seed Biology/ Ecology Research

The seed biology/ecology research focuses on understanding the impact of biotic factors such as selective disease and plant competition and abiotic factors such as light, soil fertility, moisture, soil

Invasive Weed Biology Research

This work focuses on determining those attributes of exotic invasive plants that contribute to their invasiveness and the specific features of habitats that influence their susceptibility to invasion

Biological Weed Control Research

Current/Future projects focus on the:

  • Influence of Bt corn for corn rootworm (CRW) (Diabrotica spp. (Coleoptera: Chrysomelidae) control on post-dispersal

Integrated Weed Management

The integrated management of weeds (IWM) is a final focus of my research and aims to make use of a combination of control strategies (e.g. cultural, mechanical, biological, chemical) to effectively
