Emeritus Appointment

Office: 541-737-5434

Bernadine’s extension, research, and teaching programs focused on physiology and production systems of berry crops. She also served as the OSU lead on the USDA/ARS-OSU Cooperative Berry Crops Breeding Program, co-releasing 38 cultivars for the industry. Bernadine enjoyed teaching three undergraduate and two graduate courses and advised 21 graduate students. In her career, she published 150 refereed scientific journal articles, 39 papers in Acta Horticulturae, the proceedings of the International Society for Horticultural Science (ISHS), and 24 book chapters. Bernadine co-authored 71 OSU Extension Service publications and shared her knowledge with berry industries in Oregon, nationally, and internationally through trade journal articles, presentations, workshops, field days, online courses, and webinars. Her research outcomes in modified planting densities, pruning techniques and severity, mulch types, optimization of fertilization programs, methods to improve fruit quality, and best organic production systems were estimated to increase value of the berry industries more than $10 million per year in Oregon alone; many of these systems were adopted nationally and internationally.

Bernadine’s service to the university and professional organizations was broad including mentoring junior faculty and being on promotion and tenure committees in the department and the college, co-convening national and international conferences, and serving as chair of the Section Vine & Berry Fruits in ISHS, and she continues as an Executive Council member for the ISHS.
