I have spent years studying the composition and expression of human scent from its use as a forensic identifier to the underlying indications it yields about human health. I completed my doctoral studies at Florida International University where I established an instrumental method (using gas chromatography- mass spectrometry) that allows human scent samples to be associated to one another. Further development of tools like these will eventually allow us to quantify the similarity between two samples of human scent evidence and say how similar or dissimilar they are to one another.
