Greeting from the Expert

Welcome to "Ask an Expert". I will be happy to exchange ideas and to answer or find answers to questions about physical factors related to soybean grading factors or soybean storage, handling or drying in Midwest climates. My appointment is not in extension, but rather in teaching and research. Through this forum of exchange, I hope to learn from you as well.

Research Experience:

Dr. Paulsen's research interests have concentrated in the area of corn, soybean and grain quality. His published work includes methods for detecting physical quality characteristics of soybeans and corn, determining quality loss and temperature changes during export for shipments of grain, grain damage during combine harvesting, seedcoat dye tests, machine vision for detection of fungal damage in soybeans, and near-infrared spectroscopy for detecting extractable starch in corn. His teaching has centered on courses dealing with Grain drying, handling and storage.
