Research Interests


Dr. Eric Parker's Research Interests

Solar System: Astrochemistry

Applying liquid chromatography- and mass spectrometry-based analytical techniques to analyze complex mixtures for biomolecules considered to be important for life. This includes analyzing extraterrestrial samples (e.g., meteorites and micrometeorites) and samples resulting from laboratory simulations of prebiotic environments. Molecules of interest in these studies include amino acids and peptides.
