Program Graduate Students


Alex CornwallAlex Cornwall is a lifelong native of Western Washington and being surrounded by such a lush environment, he developed a great love of plants and nature. He graduated from Washington State University in 2010 with a BS in Environmental Horticulture and joined the USDA-ARS Plant Introduction Unit in Pullman in 2011 as the Field Technician for the Horticultural Crops Program regenerating the highly diverse collection under the direction of the curator, Barbara Hellier. He has worked with the USDA for the last 10 years and will begin his studies in a PhD in horticulture in conjunction with his work in the fall of 2020 with major advisor Dr. Carol Miles. His project will be identifying Lactuca sp. with genetic barcoding and taxonomy and gene exploration of wild relatives of Lactuca sativa. Alex’s personal interests include running, botanical illustration and the fine art of cheese making.


Aidan Kendall

Aiden Kendall is from Holderness, New Hampshire and has been working on farms and orchards since 2009. He graduated from the University of Montana in 2017, where he discovered his enthusiasm for sustainable agriculture. Aidan recently spent a season at the Western Agricultural Research Center in Corvallis, MT helping with several ongoing research projects including apple bloom phenology modeling. He has decided to pursue a Master’s degree in Horticulture in the fall of 2020 to continue to perform resource conservation research and will be studying regulated deficit irrigation and the effects of mechanical hedging in cider apples.
