We are searching for a postdoctoral research associate to join a NASA Solar System Science funded project. The research includes analyses of a full range of simple and complex organic compounds in extraterrestrial samples (carbonaceous meteorites, asteroid samples) using GC/HPLC/UPLC chromatography and quadrupole/high resolution orbitrap mass spectrometry techniques, as well as construction of an interactive GCMS and chromatography database for organic compounds in extraterrestrial samples. Carbonaceous asteroids and meteorites contain a full suite of Cosmo-chemically or abiotically synthesized organic compounds including over 70 amino acids, peptides, numerous nuclear bases (including ones used in DNA and RNA), simple and complex sugars, carboxylic acids, hydroxyl acids, hydrocarbons, S- and N- containing organic compounds. These compounds have been hypothesized to have seeded life on Earth. Comprehensive analyses of these compounds require state-of-the-art organic analytical methods, particularly advanced chromatography and mass spectrometry techniques.
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
Qualifications
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. Application instructions
