Field Assistant
Email Address: adam.elcan@wsu.edu

Adam Elcan’s work focuses on cider apple research with Aidan Kendall in addition to helping with other Vegetable Horticulture projects. Born and raised in the foothills of the Blue Ridge mountains in Virginia and currently residing in Bellingham, Adam made the move from the east coast after graduating with a B.S. in Geology from Appalachian State University in Boone, NC. During the winter months he can typically be found exploring the Cascades on skis and honing his skills as an amateur photographer. He also enjoys hiking, biking, and sea kayaking when there’s no snow in the mountains and has recently been experimenting with brewing fruit wines.

Seth Brawner

Program Graduate Students:

Seth Brawner
Graduate Assistant
Email Address: seth.brawner@wsu.edu

Seth Brawner grew up on a small farm near Madison, Indiana where he developed a deep reverence for the natural world. During his time studying ecology, geology, and music at DePauw University, Seth worked on small, organic farms in Indiana, the Netherlands, and Norway — discovering a passion for regenerative horticulture. After graduating in 2020, he took over as DePauw’s Campus Farm Manager and Assistant Director of Sustainability. In this role, Seth implemented a small apple orchard and grew organic produce for the campus dining hall and surrounding community. Seth moved to Washington in 2021 and decided to pursue a Master’s degree in Horticulture in the Fall of 2022 to expand his horticultural knowledge and skill sets. Seth’s research will focus on the mechanized hedging and harvest of cider apples.

Alexander Cornwall
Ph.D. Student
Email Address: acornwall@wsu.edu

Alex 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.
