Research Focus & Interests  

Dr. Andreasen's scientific expertise and experience are in the areas of comparative clinical pathology, with primary research emphasis in granulocyte function and use of immunomodulators during bacterial diseases; pathogenic mechanisms of host cellular interactions and infectious agents; specifically in poultry and response and immunomodulation to Salmonella enteritidis; and fish cell function with immunomodulators. Additional involvement has been with foreign and emerging animal disease education, diagnostic learning, and teaching methods.
