Office: George White Bldg., Room 205
Area of Interest
My long term research interest is in improving reproductive efficiency in farm animals. I have focused on control of ovarian and testicular function. My interest in the ovary is with steroid hormone production in the granulosal and luteal tissue. We have recently isolated functional mitochondria from bovine corpora lutea (site of rate limiting step in progesterone synthesis) and found that both ATP and progesterone synthesis are reduced when PGF2a are added to the media.
I have throughout my academic career been interested in the efficiency of livestock production. I have worked with a group of colleagues interested in growth. For many years I have worked with a colleague interested in food safety.
Dr. Hoagland is also advisor of Alpha Gamma Rho and Block & Bridle.
