The overall theme of this research is forensic proteomics. Specifically, this project aims to build a comprehensive and in-depth keratin (e.g., skin/hair) peptide mass spectral library for human identification using genetically variant peptides (GVPs), while accounting for a diverse array of experimental introduced artifacts, using modern LC-MS instruments and custom software tools. Individuals with a background in proteomic sample preparation, mass spectrometry, and software development are encouraged to apply as well as an interest in forensics and measurement quality assurance.
