Lupinous sulphureus (sulfur lupine)	Cattle grazing lupine pastures	Lupine-induced crooked calf	Goat surgery: cleft palate repair

 

Research Interests:

The effects of poisonous plants and natural toxins on reproduction in livestock including embryonic and fetal growth and development.

 

Significant Accomplishments:

• Determine that locoweeds cause reproductive dysfunction in livestock and characterized the effects in sheep and cattle.
• Evaluated alkaloids from larkspur in mouse bioassays and determined structure activity relationship.
• Developed a Spanish goat model to determine the mechanism of action of lupine-induced "crooked calf syndrome" in cattle, evaluated the toxicity of 10 alkaloid teratogens and their structure activity relationship.
• Callaborate with Lahey Clinic Medical Center on the biomedical application of the goat model to improve treatment of cleft palate in children.
