Research Interests

I conduct research on the following crops: blackberry, blueberry, raspberry, strawberry, hardy kiwifruit, cranberry, and minor berry crops. My research interests are in the following areas:

• whole plant physiology including yield components, flower bud initiation, carbon partitioning
• alternative production systems that sustain or improve yield and quality yet reduce costs
• cold hardiness of trailing blackberry
• improving machine-harvest efficiency
• nitrogen partitioning/nutrition
  
  
• I am also the OSU lead on the cooperative OSU-USDA berry crop breeding program (geneticist: Dr. Chad Finn, USDA/ARS, Corvallis) and coordinate the evaluation of selections of strawberry, raspberry, blackberry, and blueberry at the NWREC with the objective of finding new commercial cultivars for the Pacific Northwest.
