This document lists 24 publications and presentations by Shaoxia Yu and collaborators from 2005 to the present related to bioanalysis and the development of methods for quantifying drugs and metabolites in biological samples using mass spectrometry. Key areas included using direct analysis in real time (DART) to enable bioanalysis without sample cleanup, microLC approaches for routine bioanalysis, and quantification of monoclonal antibodies and antibody-drug conjugates. Methods were applied to samples from multiple species for late stage drug discovery.
