Bio

Ali Kocak research interests fall into two categories:

1) The use of Attenuated Total Reflectance Infrared and Raman (FT-Raman and Confocal Raman    microscopy) Spectroscopy techniques to study the structure of fibers, hair and other forensic evidence; and

2) Forensic evidence analysis developing more sensitive sampling techniques

such as Transflectance Infrared Spectroscopy to study minerals and plant matter.
