Biography

Dr. Erin Baker is a bioanalytical chemist with 12 years experience utilizing ion mobility spectrometry in conjunction with mass spectrometry (IMS-MS) to study biological systems. Her research involves the development and evaluation of high-throughput LC-IMS-MS analyses to quickly study numerous samples in a short time period without losing valuable biological information. Dr. Baker's technical background includes evaluating short LC gradients for use with IMS-MS in proteomic analyses, as well as studying the number and quality of features detected with LC-IMS-MS and comparing them to existing LC-MS and LC-MS/MS instruments such as the LTQ-Orbitrap and LTQ Orbitrap Velos.
