Erin.Baker's picture

Dr. Erin Baker is a bioanalytical chemist with 14 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 omic 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.

Research Interests:
  • Separation, sensitivity and dynamic range enhancement of metabolites, lipids, peptidesand proteins in complex biofluid mixtures
  • Development of HPLC methods and mass spectrometry instrumentation
  • Structural variations between biological molecules in the solution, solid and gas phases
  • Ph.D., Chemistry (specializing in Physical Chemistry), University of California, Santa Barbara, 2001-2005.
  • B.S., Chemistry (minor in Mathematics), Montana State University, Bozeman, 1997-2001.
