Rae Eaton

Rae Eaton earned B.A degrees in Chemistry and Biochemistry at Oberlin College in Ohio, with a focus on bioanalytical chemistry. As an undergraduate she work under Dr. Rebecca Whelan of Oberlin College, discovering DNA aptamers that could selectively bind HE4, an ovarian cancer biomarker, to facilitate the creation of new ovarian cancer assays. She also worked under Dr. Mark Parkin of Kings College London on an on-line microchamber that was used to metabolize performance-enhancing drugs for immediate analysis by liquid chromatography-mass spectrometry.

Her research in the Bush lab focuses on using native mass spectrometry to characterize the assembly, stoichiometry, and stability of proteins and protein complexes. These experiments reveal biologically relevant data that was previously inaccessible using more traditional structural biology techniques. She also works with the emerging structures for lossless ion manipulation (SLIM), which she will use to expand the portfolio and information content of gas-phase experiments for rapid characterization of protein structures and protein complexes.
