CSG Team

Clinical Scientist Group - Mayowa Agbaje-Williams PharmD MPH

Mayowa Agbaje-Williams, PharmD MPH


Mayowa is a driven clinical development professional with more than a decade’s experience in clinical research. She began in the trenches as a study coordinator, progressing to a clinical research associate for a large clinical research organization (CRO), and study lead at a global pharmaceutical company.

Her work ethic is best described as one who has a passion for learning that is infectious to others. To this end, after years of working in the pharmaceutical industry, she pursued a Doctor of Pharmacy degree and completed a PGY-1 residency training before embarking on the role of a clinical scientist.

Her love for the clinical scientist role and her experience working with vendors hired to support the clinical development programs she worked on, led her to start Clinical Scientist Group. CSG was founded on the premise that clinical development professionals of small to mid-sized biopharmaceutical companies can expect and demand solution-focused partnership and quality product from their vendors without compromising quality, time, and costs. Outside of CSG, Mayowa enjoys dancing, traveling and spending time with her family.
