Rising Stars of Separation Science: Shijia Tang

ColumnJanuary 2024
Volume 20
Issue 1
Pages: 8–9

This month we interview Shijia Tang, principal scientist at Genentech, South San Francisco, CA, USA, about her innovative research focusing on the analysis of polymers and nanomaterials used in pharmaceutical analysis. Shijia decribes the benefits of an innovative in-line mixing modulation method for 2D-LC she developed for polymer and oligonucleotide analysis. The advantages of SEC–MALS to explore aggregation mechanisms for therapeutic constrained
peptides and mRNA-lipid nanoparticles and their aggregates are also discussed.
