About
Dr. Cassius Lindqvist develops cutting-edge analytical methods for peptide characterization at Caltech. His high-resolution mass spectrometry workflows can detect peptide impurities at parts-per-trillion levels.
Summary
Created the peptide impurity atlas now referenced by FDA reviewers during new drug application evaluations.
Key Lessons
An undetected isobaric impurity that confounded a bioassay drove him to develop orthogonal mass spectrometry approaches that are now industry standard.
