Postdoctoral Research Associate
Department of Earth, Environmental and Planetary Sciences, Brown University.
We are searching for a postdoctoral research associate to join a NASA funded project. The research includes analyses of extraterrestrial samples (carbonaceous meteorites, asteroid samples) using various chromatography and mass spectrometry techniques, as well as construction of an interactive GCMS and chromatography database for organic compounds in extraterrestrial samples.
A wide range of chromatography and mass spectrometry instrumentation is available for analyzing extraterrestrial organic compounds at Brown. These include GCFID, GCMS, HPLCMS, GC-isotope ratio-MS, and a newly acquired UPLC-orbitrap mass spectrometer
(Thermo Exploris 240). The postdoc will have access to all these instruments and is encouraged to develop new research ideas and collaborative grant proposals. The initial appointment will be for one year, with the possibility of extension to three years, pending productivity and performance in the first year.
The candidate should have a strong background in analytical organic chemistry using various GC, HPLC/UPLC, and mass spectrometry techniques, with a Ph.D. in Analytical chemistry, Organic Geochemistry, astrobiology or related fields. Past experience in meteorite and asteroid research is a plus but not absolutely required.
The ideal candidate should also have significant experience and expertise in MATLAB and/or Python coding as well as strong motivation in applying artificial intelligence in analyzing complex organic assemblages and discovery of new proxies for various Cosmo-organic chemical processes. Strong motivation and interest in academic research in cosmo-organic chemistry and/or origin of life topics are important.
The postdoctoral research associate will be directly supervised by Prof. Yongsong Huang, with collaboration with Dr. Philipp Heck at University of Chicago. Development of novel internal and external collaborations is strongly encouraged.
Questions may be directed by email to DEEPS@brown.edu. The position can start date as early as August 1, 2026. Degree completion is required by the start date of the appointment and may be from a relevant field of study including chromatography and mass spectrometry, organic geochemistry (preferably related to planetary science or astrobiology), Astrobiology, cosmo-organic chemistry.
For this position, Brown offers only the J-1 visa classification to scholars who need immigration sponsorship in order to enter the U.S. and commence lawful employment under the terms of their appointment.
Applicants should submit a curriculum vitae, three letters of recommendation, and a 3-5 page statement of research that includes a summary of research accomplishments, current research goals, and a short overview of proposed research to be conducted during the fellowship. Candidates should address how they would contribute to the research mission of our diverse and inclusive living-learning community.
