The Office of Fellowships and Internships is offering an Interdisciplinary Postdoctoral Fellowship in the area of biomolecular mass spectrometry. Research proposals must focus on mass spectrometry analysis from any type of museum or research sample including artwork, objects, animal, or plant tissues. Projects must integrate one or more analytical techniques into their specific research plan including proteomics and biomolecular mass spectrometry, gas chromatography mass spectrometry, liquid chromatography mass spectrometry, ambient mass spectrometry, stable isotope mass spectrometry, or inductively coupled plasma mass spectrometry. Data collection and analysis via mass spectrometry should be the primary basis for informing and answering research questions and should constitute a significant portion of the research. The successful applicant will conduct analyses in at least one of the Smithsonian’s mass spectrometry facilities (MCI Biomolecular and Proteomics Mass Spectrometry Laboratory in Suitland, MD; MCI Stable Isotope Mass Spectrometry Facility in Suitland, MD; STRI Stable Isotope Laboratory in Panama City, Panama; MCI ICP-MS Laboratory in Suitland, MD; FSG Department of Conservation and Scientific Research).

Applicants must have completed or be near completion of the Ph.D. Recipients who have not completed the Ph.D. at the time of application must provide proof of completion of the degree before the fellowship begins. Please go here for details on the SI fellowship program. Applications must be submitted by December 1, 2017.

Applicants must propose to conduct research in-residence for a period of 12 months. Applicants interested in this fellowship are strongly encouraged to contact potential advisors/hosts at any of the Smithsonian’s various Museums and Research Units prior to proposal preparation and submission. The fellow can work exclusively with any of the mass spectrometry facilities listed above or jointly with a co-advisor in a different unit if desired. Please consult the research staff listed in SORS.
