Research Emphasis
I am currently conduction research on influence of production practices
on weed seedbanks, spefically giant ragweed, horseweed, chickweed,
and henbit. My previous research has examined waterhemp population
dynamics in corn, specifically the influence of tillage on seedbank
behavior (emergence, persistence, distribution) and the effect of
emergence date on waterhemp survival, competitiveness, and seed
production in corn. I have also been involved in a project assessing
the distribution of common milkweed across Iowa to determine whether
changes in weed management practices are influencing the prevalence
of milkweed in agronomic fields.
My Background
I am originally from a grain and livestock farm in northwest Iowa.
I completed my B.S. at Iowa State University in May 2001 in Agronomy
and my M.S. also at Iowa State in May 2003 in Crop Production and
Physiology under Dr. Robert Hartzler.
