Tamra Jackson-Ziems, Extension Specialist and Professor, joined the faculty of the Department of Plant Pathology at the University of Nebraska-Lincoln (UNL) in April 2005 after completing her graduate degrees at the University of Arkansas and University of Illinois-Urbana. Her appointment is split between extension, research, and teaching 80/10/10%, respectively, with statewide responsibility for diseases of corn and grain sorghum. Her extension activities encompass educating clientele about disease identification, prevention, and management. And her research projects encompass a broad range of topics, including bacterial leaf streak, Goss’s bacterial wilt and blight, use of fungicides for disease control, and plant parasitic nematodes of corn. During her time at UNL, she has delivered more than 180 invited presentations in 16 states and is the 2016 recipient of both the Nebraska Cooperative Extension Association’s Award for Outstanding Creative Programming (for an individual) and the Nebraska Ag Business Association’s Education and Research Person of 2016 Award.
