Dr. Allen's research focuses on clinically oriented and diagnostic anatomic pathology. He uses gross postmortem examinations, histopathology, ancillary diagnostic tests, fundamental epidemiological techniques, and experiments to investigate naturally occurring diseases of domestic animals. He has been investigating congenital hypothyroidism of foals for many years.
