About the Author: TIMOTHY D. VEENSTRA, PhD, is Director of the Laboratory of Proteomics and Analytical Technologies at the Frederick National Laboratory for Cancer Research. Dr. Veenstra and his lab group develop and apply chromatography and mass spectrometry approaches to characterize protein complexes and the role of post-translational modifications in these complexes. Additionally, they use high-throughput proteomic approaches for the discovery of biomarkers for disease as well as proteomic and metabolomic technology for the interrogation of clinical samples. Dr. Veenstra has coauthored more than 300 peer-reviewed publications and is the coeditor of Proteomics for Biological Discovery.
