Research Interests

Dr. Al-Dissi’s research focuses on studying the effects of toxins on animal and human health. He is currently investigating the effects of ergot alkaloids on the vasculature and the mechanisms of these effects. His research team utilizes an arterial tissue bath system to study these effects in sheep after in vivo exposure.  

Another area of interest for Dr. Al-Dissi is liver regeneration. His research team is investigating the expression of metallothionein in the diseased liver of dogs, cats and horses and its relation to liver regeneration, inflammation, fibrosis and bile duct proliferation.
