Analysis of TNT, DNA Methylation, and Hair Pigmentation via Gas Chromatography-Mass Spectrometry and Spectroscopic Techniques

This work consisted of three projects. The first focused on analyzing TNT residue collected from post-blast backpack debris with an M-Vac. The second focused on analyzing DNA methylation in blowflies to determine a post-mortem interval based on the blowfly's age. The third focused on analyzing hair pigmentation to build a statistical database to further support evidence presented in court.
