About

Christopher J. Morrison is a biochemical engineer and chromatographic separation scientist whose research has made meaningful advances in the purification of therapeutic proteins, particularly monoclonal antibodies (mAbs). His work centers on displacement chromatography, hydroxyapatite-based separations, and the development of chemically selective displacers for high-resolution protein purification. Morrison's most impactful contribution — cited 27 times — demonstrated that selective desorption on ceramic hydroxyapatite (CHT) could effectively isolate monomeric mAbs from problematic aggregates and post-protein A impurities, a critical challenge in biopharmaceutical manufacturing. Complementing this, his investigations into unique selectivity windows on hydroxyapatite systems and multimodal cation exchange chromatography expanded the toolkit available to process scientists for resolving difficult protein mixtures. A recurring theme across his work is the intelligent use of robotic high-throughput screening platforms to systematically identify and characterize novel displacer molecules, dramatically accelerating experimental design. His studies on displacer analogue libraries further deepened mechanistic understanding of how molecular structure governs separation efficacy. With a cumulative citation record reflecting consistent relevance in the downstream bioprocessing field, Morrison's research offers practical, scalable strategies for advancing protein purification science.
