President- GlycoMyr, Inc. 2020 to present

Dedicated to discovering new uses for plant based vitamin D compounds in man and animals.  Developing improved methods of supplementing piglets with vitamin D and E.  Developing oral calcium boluses with vitamin D glycosides for hypocalcemia reduction in cows. 

Iowa State University and USDA-ARS, National Animal Disease Center; 1985-2020. conducted research on metabolic diseases of animals and the effect these diseases had on infectious disease resistance, with emphasis on dairy cows.  Also did basic and applied research on milk fever and other mineral disorders of dairy, swine and poultry. This work included demonstration that diet potassium, not calcium causes milk fever and the effect of potassium can be overcome with adding anions to the diet.  Working on Solanum glaucophyllum boluses to help reduce hypocalcemia in dairy cows.

 Examining potential of plant derived vitamin D analogs to prevent/treat cancer and immune mediated disease.  Also pursuing research to develop methods to improve immune function in the dairy cow around the time of calving to prevent diseases such as mastitis, metritis and retained placenta.  Continue to do work on the effects of subclinical hypocalcemia and other mineral disorders in the periparturient cow.

Teach nutrition courses, Physiology and Histology Courses, and teach 4^th year students during Dairy Production Medicine rotations.
