Alessandro Butté received his Ph.D. in Chemical Engineering in 2000 from ETH Zurich. After a two-year post-doc at the Georgia Institute of Technology, he join the group of Prof. Morbidelli at ETH Zurich and completed his habilitation in 2008. During this period, his research activities focused on polymer engineering, production of nano-materials for protein purification (monoliths by reactive-gelation) and chromatography purifications of peptides, proteins and Mabs. In 2008, he joined Lonza as responsible for downstream activities in the sectors small molecules and peptides. He is currently leading the share best practice team for chromatographic and membrane separations and he is involved in the pilot program to introduce Quality by Design into R&D. He is author of more than 30 papers on international peer reviewed journals and several book chapters.
