Graduate Students under Dr. Jason Ferrell
Michael Durham has been a Biological Scientist at the University of Florida since 2007. He ran the pesticide program at the IFAS-PSREU in Citra, FL until 2010 and now currently works with Dr. Jason Ferrell conducting Weed Science research in Gainesville, FL. From 2001 until 2007 he worked for the USDA-ARS Plant Science Unit in Raleigh, NC as a Biological Technician. In 2000, he received his B.S. degree in Botany from the University of Florida. He is currently working towards an M.S. degree in Weed Science at the University of Florida. His research focuses on using aminocyclopyrachlor for vegetation management on Florida's right-of-ways.
Ph.D. Candidate. Dissertation title: Integrating dicamba into cotton production: understanding drift and soil activation.
I grew up in Northeast Arkansas and received my bachelor’s degree from Arkansas State University in 2009. I worked in a research lab at the Arkansas Biosciences Institute before starting my master’s degree at UF under Dr. Jason Ferrell. My research interests are agronomic weed science and ornamental plant management.
Ph.D. Candidate (co-chair; David Wright, chair). Dissertation title: Herbicide sensitivity and management of Brassica carinata for biofuel.
M.S. Candidate. Thesis title: Production practices that influence sesame tolerance to soil applied S-metolachlor.
