Erin Shammel Baker is an American bioanalytical chemist specializing in developing ion mobility-mass spectrometry hybrid instruments for biological and environmental applications.

[1] Her interests in chemistry stemmed from a determination to understand the arsenic and cyanide pollution from gold mines that affected animals on her family's ranch and local wildlife.

[2][3] She obtained a bachelor of science in chemistry, with a minor in mathematics from Montana State University in 2001, where she conducted research using ion mobility spectrometry in Eric Grimsrud's laboratory.

[1][4][5] She continued with research in ion mobility spectrometry in graduate school, and received a PhD in chemistry under the direction of Michael T. Bowers from University of California, Santa Barbara in 2005.

[11] She is the director of the Core of Advanced Platform Technologies Used for Remediation and Exploration (CAPTURE), the analytical branch of the PFAS Superfund Research Centre.
