Steven Cramer is the William Weightman Walker Professor of Chemical and Biological Engineering at Rensselaer Polytechnic Institute, Troy, New York. He is currently conducting research on several areas related to protein-surface interactions including: rational design of high affinity and chemically selective displacers for protein and oligonucleotide purification in ion exchange and hydrophobic displacement systems, multi-scale modeling of complex chromatographic behavior, molecular modeling of selectivity and affinity in multimodal chromatographic systems, spectroscopic investigations of protein-surface interactions, chromatography on a chip, novel separation systems for proteomics, smart biopolymer affinity separation systems and development of affinity peptide based biosensors. In addition, Professor Cramer is known worldwide for his expertise in separations in general. He is the Editor-in-Chief of the International journal Separations, Science and Technology. Professor Cramer was the awarded the Alan S. Michaels Award for the Recovery of Biological Products (ACS Division of Biochemical Technology). He was also awarded Rensselaer’s School of Engineering Research Excellence Award, a Presidential Young Investigator award from the National Science Foundation, the Early Career Award from Rensselaer Polytechnic Institute as well as several teaching awards. Professor Cramer has been elected a fellow of the American Institute of Chemical Engineers and the American Institute for Medical and Biological Engineering. He has also chaired several prestigious meetings including the International HIC/RPC Bioseparations Conference, the ACS Recovery of Biological Products Meeting and the Gordon Conference on Reactive Polymers. Prof. Cramer has published 150 papers in peer-reviewed journals and has 9 patents. Importantly, he has produced 36 Ph.D. students who have gone on to leadership positions in the biotechnology industry and academia.
