Steven Cramer

Steven Cramer is Institute Professor of Chemical and Biological Engineering at Rensselaer Polytechnic Institute, and a member of the National Academy of Engineering. His research focuses on protein-surface interactions and molecular bioprocessing, with significant contributions to chromatographic bioprocessing technology.

He developed the steric mass action model for ion exchange chromatography and pioneered low molecular weight displacers for protein purification. His Quantitative Combinatorial Design approach has discovered novel displacers and affinity ligands. His high-throughput screening methods transformed industrial bioprocess development.

Professor Cramer holds 11 patents with 230 publications (h-index 55, 9800+ citations). He received numerous honors including the ACS National Award in Separations Science and fellowships in AAAS, AIChE, ACS and AIMBE. He served as Editor-in-Chief of Separations Science and Technology for 20 years.

He has supervised 57 PhD graduates who now hold leadership positions in biopharmaceutical companies worldwide. Current research includes gene therapy downstream manufacturing, continuous mRNA processing, and big data modeling.
