Zachary FrederickCongratulations to Mr. Zachary Frederick, who is starting his PhD this fall with Dr. Dennis Johnson, Professor of Plant Pathology.  Zack has been selected to receive the prestigious Achievement Rewards for College Scientists (ARCS) Scholarship from the ARCS-Seattle Chapter (

ARCS Foundation is a national organization of 17 Chapters serving 53 of the nation’s premier research universities.  Nationally, over $82 million in financial support to more than 14,000 students has been awarded.  The Seattle Chapter, founded in 1978, currently supports more than 120 PhD candidates at the University of Washington and Washington State University.  The Seattle Chapter has been recognized as a Washington State University Laureate and to date has contributed >$13 million to 1000 talented scholars at the state’s two research universities.

Other Plant Pathology ARCS Fellows include Dr. Jane Stewart (PhD, WSU, with Dr. Tobin Peever), Ms. Christian Aguilar (PhD student with Drs. Mark Mazzola and Chang-Lin Xiao), Ms. Andrea Garfinkel and Ms. Katie McKeever (PhD students with Dr. Gary Chastagner), and Ms. Amy Salamone (PhD student with Dr. Debra Inglis). Plant Pathology is one of only four departments in the entire WSU system to be chosen as an ‘ARCS Department’ by the ARCS Foundation.

Zack is a native of New York and received his BS in Agricultural Biotechnology in the Department of Natural Sciences, State University of New York at Cobleskill. He then decided to go to graduate school and joined Cornell University’s Department of Plant Pathology and Plant-Microbe Biology where he just finished his MS degree. For his MS, Zack worked on apple scab which is caused by Venturia inaequalis, and investigated the effects of QoI fungicide resistance on apple scab management programs. Three aspects that he looked at included the prevalence of qualitative resistance to QoI fungicides in Northeastern U.S. V. inaequalis populations, the significance of the G143A point mutation in QoI resistance, and its stability in the absence of selective pressure.

At WSU, for his PhD dissertation research, Zack will focus on the disease management of the fungal pathogen Verticillium dahlia,the causal agent of verticillium wilt, which is an important disease of both potato and mint for regional growers.

Zack had an undergraduate internship in 2011 and worked as a Summer Scholar in 2010 at the New York State Experimental Research Station in Geneva under Dr. Kerik Cox. While in high school, he interned in a plant genome research project at the Boyce Thompson Institute, Cornell University, Ithaca under Dr. Maria Harrison.

Zack is a member of the American Phytopathological Society and published papers on apple diseases and their management.
