Since graduating as a PhD in Biochemical Engineering in 2013, Yu Linling has been working a lecturer in Tianjin University, focusing on the investigation of protein interfacial behaviors in pharmaceutical protein production and new drug development, such as protein chromatography, protein folding and aggregation, etc. Major Achievements include: 1) H-index 10 (H-index 7 for non-self-citations of papers as first author or corresponding author); 2) Investigation on protein chromatography: A mechanism named “chain delivery” effect for the fast protein mass transfer was first proposed, and several novel polyelectrolyte-modified resins with salt tolerance, high binding capacity, and rapid mass transfer were designed. A review about protein behavior at chromatographic surfaces was published in Journal of Chromatography A by invited (non-self-citation was 19), as well as another invited review about protein chromatography with grafted polymeric ligands was published in CIESC Journal; 3) Investigation on protein folding and aggregation for the development of inhibition strategies of the amyloid β peptide (Aβ) aggregation, in order to help the curing Alzheimer's disease (AD).
