Professional Summary


For two decades Dr. Crayton traveled the county and also abroad addressing audiences at scientific conferences and engaging them in his research findings.  As Program Coordinator for Biology (Dept Chair) Dillard University and former Assistant Professor of Genetics at Xavier University, Dr. Crayton has lectured to literally thousands of aspiring physicians, pharmacists, healthcare professionals, and research scientists at these Historically Black Colleges and Universities. Born the grandson of Mack Crayton, Sr. a Louisiana sharecropper with less than a sixth grade education, in 2003 Mack Crayton III became the first African-American to earn a PhD in Genetics from the University of Connecticut, Storrs.  Presently, Dr. Crayton works to promote science literacy among all Americans as an Author and Educational Motivational Speaker.


Drawing from his career experiences as a trained scientist, promoter of science literacy, author, and Christian believer, Dr. Crayton engages audiences in inspirational discussions about the utility of science in developing a greater understanding of our humanity and to develop a deeper relationship with the Creator.   His book, Brain, Mind, Soul and Spirit: The Interface between Science and Scripture was released in 2018.  This work serves as the backdrop for exploring topics such as: The powers of the human mind, faith, and spirituality; The Biology of human nature, gender identity and sexual orientations.  Evolution of Creation: The Interface Between Science and Scripture (2021) interfaces the biblical creation story with present-day scientific knowledge that pertains to the development of our universe, the origins of life on earth and the evolution of man.   This book closes with a history of genetic engineering, and an introduction to gene editing (CRISPR). Additionally as a guest lecturer, Dr. Crayton  expands on topics that include: precision medicine for treatment of health disparities; the genetics of race; and the historical fear of medical research within the African American community and the necessity for African Americans to participate in present-day research studies.  


Dr. Crayton currently resides in New Orleans, LA and has been married to Jabial Reed since 2016, the couple has no children.
