- Douglas M. Stocco, Ph.D. was the 2016 Parker Lecturer at the XVII Adrenal Cortex Meeting.
- Dr. Stocco's background, education and history in science are presented.
- Dr. Stocco is best known for discovering the steroidogenic acute regulatory protein, StAR.
- Dr. Stocco has been widely recognized for his outstanding scientific contributions.

Douglas M. (Doug) Stocco is Professor Emeritus at Texas Tech University Health Sciences Center in Lubbock, TX, and is internationally renowned for his work characterizing the steroidogenic acute regulatory protein, StAR. Stocco's laboratory isolated and cloned StAR from mouse Leydig MA-10 cells, collaborated on the demonstration that StAR mutations cause congenital lipoid adrenal hyperplasia, and delineated much of what is known about the intracellular pathways that regulate its production. This work resolved a decades-long quest to identify the mechanism underlying the acute regulation of steroidogenesis.
