Steven L.  Holshouser, Ph.D.

Chief Scientific Officer

Dr. Steven Holshouser is an innovative scientist with an all-inclusive background for the foundations of drug discovery. Through the years, he as gained experience in synthetic chemistry and molecular biology in both the academia and industry setting. He received his BS in Biochemistry and BA in Chemistry at the College of Charleston in Charleston, SC while simultaneously obtaining Summer Undergraduate Research Program (SURP) grants award by the Medical University of South Carolina to develop his skill set in molecular biology. After graduation, Dr. Holshouser furthered his medicinal chemistry skills by maintaining a synthetic chemistry lab, and constructing an in vitro testing facility in order to expedite compound development in-house. Further pursuing his education, he earned his PhD in Drug Discovery and Biomedical Sciences at the Medical University of South Carolina, Charleston, SC. During his training as a PhD student, he took a brief intermission from his studies to work for GlaxoSmithKline where he expanded his medicinal chemistry knowledge by developing compound through physical and computational drug development for the treatment of Chronic Obstructive Pulmonary Disease (COPD). After Graduation, he accepted the position as Head of Discovery for Firststring Research to identify novel uses for a topical wound healing peptide (Granexin©) in phase III clinical trials for diabetic foot ulcers. Currently, Dr. Holshouser is Director of Screening and Lead Optimization at the Medical University of South Carolina’s Drug Core, located in Charleston, SC. His experience in compound screening, synthesis and purification allows him to work on a broad range of projects.
