Marcelo Zimmer

Botany and Plant Pathology

Weed Science Specialist

Marcelo Zimmer is originally from a small farm in southern Brazil and received his Bachelor’s degree in Agronomy in 2014 from the Federal University of Pelotas (Brazil). In 2015, Marcelo joined the Purdue Weed Science Lab as a M.S. student under the supervision of Dr. Bill Johnson, where he researched the management of glyphosate-resistant horseweed utilizing a new herbicide from Dow AgroSciences (Elevore), graduating in 2017. Currently, Marcelo works as the Weed Science Program Specialist, while also pursuing a Ph.D. degree in Weed Science. His research is investigating the molecular and physiological basis for the different glyphosate-resistance mechanisms in giant ragweed. Understanding of these resistance mechanisms may be helpful to develop new weed management strategies.

Expected graduation: May 2022.
