Dean K. Pettit, Ph.D.

Senior Vice President, Biotherapeutic Sciences

Dean brings a broad scientific background, and a deep commitment to advancing innovative technologies and challenging the industry to improve worldwide access to protein therapeutics.

Dean served as CSO and founding partner of Just Biotherapeutics. Over his career, Dean has held numerous leadership roles in process development functions at Immunex and Amgen, including Drug Delivery, Formulation, Analytical and Formulation Sciences. Most recently, Dean served as Executive Director of Drug Substance Development at Amgen, responsible for Cell Culture and Cell Line Development, Purification, Analytical, and Bio-characterization functions. While at Amgen, Dean played a key role in the development of a concept known as Product Attribute Control (PAC) that aims to actively measure the attributes of biopharmaceuticals during manufacturing and provide real time process control. This concept has led to the development of novel processing and analytical technologies which will drive an improvement in product quality and a reduction in the cost associated with product release testing in the biopharmaceutical industry. Dean began his career working with medical devices at Allergan and then earned his Ph.D. and completed a postdoctoral fellowship in Protein Engineering at the University of Washington Department of Bioengineering.
