Biography

My past research interests include human identification and the application of classical forensic serology techniques to modern RFLP and PCR-STR DNA typing techniques and refining classical forensic serology for modern applications.

 

I have supported research on antimicrobial proteins in insect Central Nervous Tissue(i.e. Lubber Grasshoppers)

 

I am presently researching the antimicrobial effects of sucralose (Splenda(R)) on the gut bacterial microbiome.
